Have you hefted a median college-kid’s backpack recently? Years in the past, when a few of us were in school, we carried perhaps two or three textbooks at a time. These days, nonetheless, with many schools eliminating lockers for security causes, college students typically carry all of their materials, all day long. One 2004 research of 3,498 middle-faculty college students discovered a median backpack weight of 10.6 pounds, with some ranging as excessive as 37 pounds. Not surprisingly, sixty four p.c of the youngsters stated that they’d experienced back pain, which correlated on to the amount they carried. That is, the extra the backpack weighed, the better the probability the student would report pain. In response, a number of well being organizations advise that student backpack weight be limited-the American Chiropractic Association suggests that children carry no more than 10 p.c of their physique weight, and the American Occupational Therapy Affiliation recommends 15 %.

If equal pointers were adopted in the equestrian world, the loads placed on a 1,000-pound horse would be restricted to a hundred to one hundred fifty pounds. After all, horses routinely bear far heavier burdens without apparent problem. But that doesn’t imply that there’s no cost. Over the previous few years, researchers on the California State Polytechnic College in Pomona have been investigating the vary of physiologic adjustments that occur in horses after they carry varying hundreds. “Our studies dealt with energetics, to quantify the costs of carrying weight,” explains Steven Wickler, DVM, PhD, who headed the analysis staff. Among the areas investigated were how weight affects equine biomechanics, metabolism and potential soundness. Although this analysis has direct implications for elite equine athletes-particularly in such sports as racing or endurance-Wickler emphasizes that his findings potentially have a lot broader implications, extending to recreational path mounts and yard horses. “Look on the American population right now,” he says. Over the past few decades the U.S. Nationwide Middle for Health Statistics. The answer remains to be, largely, “It relies upon.” However an elevated consciousness of weight issues can go a long way toward preserving your horse healthy and sound for years to come. Exactly how a lot weight is too much? Loaded Questions All creatures in nature perform a delicate balancing act. Then again, growing and sustaining those tools requires energy, which have to be derived from available food sources. Due to the metabolic costs related to sustaining their bodies, animals tend to pack just as a lot muscle and bone as they want, with solely a little bit leeway for emergencies. On the one hand, they need to carry a whole set of survival tools-the muscles they use to sprint, leap, fly or climb out of harm’s way; the hoof, horn, tooth and claw they should battle their battles. “For example, an elevator could also be built with a posted capacity of eight folks, or not more than 1,500 pounds. “Human engineers will overbuild to anticipate extremes,” says Wickler. However, in actual fact, that cable may actually be capable of holding 15,000 pounds-that’s a safety factor of 10. However biological methods don’t try this. When a horse carries a rider, it is this “reserve capacity” that handles the extra weight, however the horse must nonetheless adjust the way in which he strikes and uses his muscles to accommodate the load. The Cal State researchers have quantified some of the ways added weight modifications the best way equine our bodies perform. Metabolism “We expected that if you weight a horse, metabolism would go up in direct proportion, primarily based on comparative literature in lots of animals, together with humans,” says Wickler. Researchers measured the quantity of oxygen horses utilized as they trotted on a treadmill carrying face masks. “The improve in your metabolism is straight proportional to the increase in the burden,” Wickler explains. 7.Four mph) or excessive (10 mph)-the quantity of oxygen they used also elevated. When weights had been added that equaled about 19 percent of body weight, an amount that's roughly equivalent to a 150-pound rider plus tack, the horses’ metabolism elevated by a mean of 17.6 % at all speeds. “So in the event you add 10 percent of your body weight, your prices go up 10 percent.” Each extra pound added to the load produces a corresponding increase within the metabolic effort required to move that load-and that’s over degree ground. For a modest grade, metabolism increases by 2.5 occasions,” Wickler provides. “If the horse is requested to trot uphill, metabolism will increase. In this part of the study, seven Arabian geldings and mares were educated to stroll and trot alongside a level fence line in response to voice commands. Economic system Not surprisingly, horses who are free to decide on their own velocity tend to slow down when weight is placed on their backs. The saddle and lead together weighed 85 kilograms (about 187 pounds), which amounted to about 19 percent of the horses’ physique weights. Not surprisingly, the extra weight triggered horses to move more slowly, decreasing velocity from about 7.Four mph to about 7 mph. They were timed as they walked and trotted the gap unburdened in addition to with a saddle weighted with lead shot. Forces on Legs Growing the burden a horse carries also will increase the ground response forces-the amount of energy that “pushes back” on the sole of the foot when it strikes the ground-that every limb withstands with every stride. “Not solely does their metabolic fee go up, however their preferred speed goes down,” Wickler says, adding that crucial discovering was that the horses’ preferred pace was probably the most economical in terms of shifting a given distance with that added weight. To learn how horses compensate for these changing forces, seven horses-4 Arabians, two Thoroughbreds and one Quarter Horse-had been trotted at a spread of speeds throughout a drive-measuring plate each on the extent and at a ten percent incline. “When you add weight when a horse is standing, the pressure of the load is divided via all 4 limbs,” Wickler says. Regular (vertical) and parallel (horizontal) forces in addition to each foot’s time of contact on the plate have been recorded on the fore- and hind limbs; each horse was also videotaped so that stride time may very well be measured. However in actual fact, there are vital variations in the amount of forces borne by the entrance and rear legs. On a stage floor the forelimbs persistently supported 57 percent of the forces while the hind limbs supported forty three %. As a result of a trotting horse seems like he's utilizing his diagonal feet in excellent tandem, it might seem as if the response forces can be evenly distributed across the two legs that support him at each section of the stride. Time of contact also different. Going uphill, this pattern of distribution shifts, with 52 % supported by the forelimbs while the hind limbs took on forty eight p.c. For the entrance limbs, time of contact didn’t change considerably whether on the level or on the incline, however the hind limbs tended to be involved with the ground longer when going uphill. At increased speeds, the 2 toes were on the ground about the same amount of time, but at slower speeds, the hind limbs tended to spend less time on the bottom-an remark that had never been made earlier than in quadrupeds, based on Wickler. Gait To study the biomechanical results of masses, the Cal State researchers trotted five Arabians at a constant velocity on a treadmill below three completely different conditions: on the extent with no load, on a ten p.c incline with no load, and on the extent whereas carrying a saddle and weights that totaled about 19 p.c of their physique mass. Carrying a load triggered the horses to depart their ft on the bottom a median of 7.7 % longer than they did while trotting unburdened. To record the movement and pace of the horses’ foot movements, an accelerometer was attached to the right hind hoof, and the periods were recorded with a excessive-speed video digital camera. Briefly, explains Wickler, carrying a load causes a horse to shorten his stride, depart his feet on the ground longer and increase the distance his physique travels (the “step length”) with every stride. All of those gait changes work together to cut back the forces placed on the legs with every step. On the level, the addition of a load precipitated the swing part of the stride to become 3 % shorter, but going uphill this part of stride lasted 6 p.c longer. Clearly, horses the world over have been carrying riders for many centuries with little sick effect. For your bookshelf: Match to Experience in 9 Weeks! Robust Street? All of those shifts in how horses carry themselves in response to weight on their backs are delicate-too slight to cause serious harm beneath normal circumstances. And but, says Wickler, “we all also know that horses generally break limbs.” The California analysis lays a framework for understanding how including weight to the horse will increase the forces his limbs must withstand. Health coaching will increase and strengthens each muscle and bone, bettering the horse’s reserve for absorbing the stresses of exertion, but at the extremes of equine athleticism cumulative stresses will be important. “A small quantity of weight can make an enormous distinction,” Wickler says. “The addition of 10 % of a horse’s weight may not be significant, but if he carries it over a hundred miles, it might turn out to be necessary.” On the racetrack, the effects of a small amount of weight are magnified by the large forces on the legs generated by galloping at extraordinarily excessive pace. As each foot strikes the bottom, whatever force isn't absorbed by bone and tendon must be taken up by the muscles. “For racing performance on a short monitor, 10 percent is a large quantity,” Wickler says. However many pleasure horses carry heavier masses than sport horses ever do, typically for hours at a time, at varied gaits over completely different terrain. The Cal State studies addressed muscular adaptations to carrying weight moderately than orthopedics, and so that they haven’t examined how weight may contribute to the incidence of bone or joint problems. It’s possible that chronic overwork leads to many tiny microfractures, which might construct up to a catastrophic break. While carrying a single heavy rider on a one-day experience just isn't prone to severely hurt a horse, through the years, a consistent regimen of this kind of work might add as much as chronic harm. “It also is sensible that back ache is perhaps related to weight,” Wickler says. There is no definitive reply largely because there isn't a method to outline the limits of security. How A lot is A lot? So how a lot weight can a horse safely carry? “While there appears to be some consensus, it isn’t as clear as one may think,” says Wickler. However that doesn’t imply that a horse who seems capable of bear a heavy load will not be accruing “silent” injury that may manifest years later as early arthritis or a sudden unexpected breakdown. Clearly, a horse who staggers beneath a pack is overloaded. Time and terrain matter, too. The same horse who without apparent strain can handle a 250-pound rider in short sessions in the arena is perhaps shaking with fatigue after an hour on a mountain path. In the absence of scientific analysis, the following source of data on maximum weight loads for horses comes from historical sources-the results of centuries of horsemanship experience, not all of which developed with the effectively-being of the horse as the very best precedence. “U.S. Army specs for pack mules state that ‘American mules can carry as much as 20 p.c of their body weight (a hundred and fifty to 300 pounds) for 15 to 20 miles per day in mountains,'” Wickler says. India’s Prevention of Cruelty to Draught and Pack Animals Guidelines, 1965, says the maximum for mules is 200 kilograms (about 440 pounds) and for ponies the utmost is 70 kilograms (154 pounds). “Packers generally try to keep packs to a hundred and fifty to 200 pounds in their animals, who must carry the dunnage on a daily basis for your complete season,” says Wickler, “so 20 % of the animal’s body weight seems to be cheap. If you happen to go quicker, meaning extra forces on the limbs and extra metabolism is needed.” Immediately, many dude ranches and public stables submit weight limits for riders, often round 200 pounds or less; the National Park Service, for instance, does not permit riders who weigh more than 200 pounds to participate in its mule journeys into the Grand Canyon. “The logical extension of this line of pondering is to never experience a horse or to make it a rule that only skinny folks can ride,” says Wickler. However, these ideas are for walking. “Obviously, that’s not going to happen. That includes not only the rider’s weight, but additionally the load of the saddle, in addition to every part else carried alongside. English saddles vary considerably by discipline however generally weigh 20 pounds or less, and some models weigh less than 10 pounds. Western saddles engineered particularly for ranchwork or sports activities similar to roping or cutting tend to be heavier, forty pounds or more; these designed for path or pleasure uses are typically lighter, 25 to 30 equestrian statue pounds, however some models can range up to 40. Australian, endurance and synthetic Western saddles are lighter-with weights ranging from 13 to 22 pounds. Gel-crammed saddle pads can add a number of pounds, as can another gear worn by the rider or tucked into saddlebags. The jury may still be out on precisely how all of this weight impacts individual horses, however something you can do to minimize the quantity your horse carries will almost certainly benefit him over the long run. “I could stand to lose some weight,” says Wickler.

Elephants are indeed the biggest land animals on the planet. An Elephant Water can retain in its trunk. There are three species found of elephants: the African bush elephant, the African forest elephant, as well because the Asian elephant. They're certainly an unofficial subfamily of the proboscidean parental Elephantidae. Elephantidae appears to be the only remaining survivor’s family of proboscideans; mastodons all seem to be extinct. Elephantidae as properly includes quite a few extinct species, similar to mammoths in addition to straight-tusked elephants. Asian elephants have relatively small ears as well as curved or degree backs, so despite the fact that African elephants possess greater ears as well as concave backs. Elephants are distinguished by a prolonged proboscis often called only a trunk, tusks, huge ear flaps, humongous legs, as well as hard but delicate skin. Breathing, helping to deliver food and water in the direction of the mouth, in addition to clutching objects are all carried out with the trunk. The large ear flaps support in both preserving a core body temperature and interplay. Tusks, which additionally are deduced from incisor teeth, are being used as both weapons and instruments for objects shifting in addition to digging. The huge quantity of weight is supported by the pillar-like legs.Elephants can certainly be found in many different of habitats throughout the whole of Sub-Saharan Africa, South Asia, as well as Southeast Asia, which would come with savannahs, woodlands, deserts, and marshlands. They seem to be plant eaters and need to remain close to bodies of water when it becomes available. How Highly effective Is An baby elephant stuffed animals Elephant Trunk? Do Elephants Like Water? How A lot Can Elephant Water Retain in Its Trunk? How Much Water Can An Elephant Suck? Why Do They Need to hold Water in their Trunk At all? How A lot Can An Elephant Swim? How Highly effective Is An Elephant Trunk? An elephant’s trunk could certainly carry upwards of 700 pounds as just an adult, enormous kudos to a system of 40,000 musculature. As a body of comparison, humans have slightly more than 600 musculature in combined quantity. Do Elephants Like Water? Trunks are indeed commonly used largely for social interplay. Elephants actually respect temperature control off in our bodies of water, and that they may enjoy the occasional romp within the water with their companions. Elephants have all the time been nice swimmers, in order that they can be used to being in water. They might maybe cool off someplace within the water whilst also “wrestling” with their companions in addition to herd members. How A lot Can Elephant Water Retain in Its Trunk? The trunk by itself can weigh up to 140 kg and due to this fact can indeed handle a few quarter of a gallon, but research findings have already shown that bull elephants could actually retain as much as 2.5 gallons. The typical trunk of an elephant appears to be typically about 6 toes long, and it can grow toward being approximately 7 feet lengthy. Elephants don’t really drink by way of their trunks, regardless of widespread opinion. Why Do They Need to hold Water of their Trunk At all? They suck up the water before lifting all of it to their mouths to devour. Elephants have been using their trunks for a whole lot of various things, which would come with consuming, vocalizing, bodily affection, as well as discovering completely different objects, in moreover to drinking and bathing. A trunk is actually as important to an elephant as arms and palms are with a human. How Much Water Can An Elephant Suck? They've been utilizing the water to spray themselves in order to cut back the heat down in addition to bath. How A lot Can An Elephant Swim? In line with the analysis venture, which was accepted for publication of the Royal Society Interface, these heavily muscled, 200-pound nasal appendages could certainly devour up three liters of water in fairly a second, a mind stream-fee equal to nearly 24 shower heads. Elephants, like most of the opposite mammalian species, have at all times been born swimmers. Elephants walk 25 kilometers each day on land. Elephants, then again, can stroll approximately to 195 kilometers if absolutely required. When elephants are already in the water, they may indeed cover numerous floor. They can swim for up to 480 kilometers, or about 300 miles. They might indeed swim totally and totally submerged underwater whereas breathing by means of their trunks. There's something very special concerning the magical world that J. Ok. Rowling created, and it's more than just the characters. Probably the greatest issues we received to expertise was Hogwarts and all the information that was shared while Harry went on his adventures with Ron and Hermione. We need to see if you'd cross even a 12 months at Harry Potter's faculty. Sure, the meals are superb, what with magical platters laden with all method of goodies, but the curriculum calls for severe study! So we're going to check your knowledge of fairly a few of the subjects, which include, but aren't limited to, Protection In opposition to the Darkish Arts, Herbology, Potions, Care of Magical Creatures, Historical past of Magic, Charms and even Divination. And we're going to quiz you on that immediately. You will must know your spells, potions elements, magical plants and extra to pass this take a look at, but if you can, we'll be really impressed. We'll ask you some fairly primary stuff and even issues that N.E.W.T.-degree students would know. Take this quiz so we would know whether or not you'd pass Harry Potter faculty or not. So, come answer these questions that you simply'd find on a Hogwarts examination. What does the Confundus Charm do? It distracts a person. It disables an individual. The Confundus Charm pusheen unicorn plush is supposed to confuse the person it's used on. It confuses an individual. Ron received the spot due to this. Hermione used it on Cormac McLaggen in order that he would miss the ultimate shot whereas attempting out for the Gryffindor Keeper position. Felix Felicis, often known as Liquid Luck, is a potion that brings luck to its drinker for a brief period of time- although the time frame varies depending on how a lot the drinker consumes. It makes a person smarter. It was used by Harry in the Half-Blood Prince to get the reminiscence of Slughorn telling Tom Riddle about horcruxes. There are 5 principal exceptions to Gamp's Law, aka, Transfiguration. What this means is that there are 5 things within the Wizarding World that cannot be used in one of these magic. Because we know that animals can be transfigured, they are the will not be one of the exceptions. A horcrux have to be destroyed. To make one, you have to hatch a rooster egg beneath a toad. This evil apply was banned during the medieval period. Basilisks, as you've seen within the Chamber of Secrets, are abnormally large serpents that are created by dark wizards. It's no surprise that Hermione knew it, but we were shocked that she used the spell on Ron after he was seen kissing Lavender Brown. The Avis charm is an advanced, N.E.W.T.-stage spell that conjures birds. Dragon blood is known in the Wizarding World for its 12 makes use of, most or all of which have been discovered by Dumbledore. This determine is claimed to take the form of a giant, black dog and is one of the crucial nicely-identified omens within the Wizarding World. In Divination, the Grim is an indication of loss of life. Ron's uncle, Bilius, reportedly saw one and died lower than 24 hours later. There are three Unforgivable Curses, and they're Imperio, Crucio and the Killing Curse, Avada Kedavra. The boggart-banishing spell is Riddikulus. Densaugoeo is a hex that causes the receiver's teeth to elongate grotesquely. Although it would not at all times vanquish a boggart, it does make them seem less threatening. Take for instance when Professor Lupin gave his Boggart lesson in 12 months three; Neville's boggart (Professor Snape) went from fearsome to humorous, sporting Neville's grandmother's clothes.

We wanted to want a contented Father’s Day to all the dads out there, both human and animal fathers alike! Weigh in on the feedback part and inform us which species you suppose is the best father figure. As a tribute to hardworking dads, we made a list of a number of the animal kingdom’s most devoted dads. Even higher, ship this text to the fathers in your life, telling them which animal father he reminds you of probably the most! He is known for lounging in the shade whereas his lioness dangers her life hunting all day lengthy. The male lion typically gets a foul rap in the case of parenting. Hunting is no straightforward task for her considering male lions eats about 65 pounds of meat per day! Nonetheless, when his pleasure is in hazard, the male lion really steps up and turns into ferociously protective of his satisfaction, which can include 30 or extra lionesses and cubs. When he senses a menace, his fatherly intuition kicks in and he does anything and all the things to make sure the safety of his family. What’s worse, when mom brings in a kill, dad all the time gets dibs on the first juicy cut earlier than mother and the children get to eat. Be a part of us on an African safari to see lions within the wild. A typical gorilla father is accountable for a clan as giant as 30 gorillas. He is sort of respectful of the mom of his children, always dining with her first before letting the kids take part on the meal. A gorilla dad is also very attentive, fending off threats by fiercely beating his chest and charging enemies. He's responsible for locating food for his group, which is a giant job seeing as gorillas typically eat up to 50 pounds of meals per day! He spends a superb deal of time with their younger till they turn out to be teenagers, taking part in lovingly together with his offspring and settling any arguments that arise between siblings. See gorillas of their pure habitat on our Uganda and Rwanda tours. He usually has to fight off other male gorillas who are recognized to kill child gorillas when making an attempt to take over the group. While the pups are young, the father hunts on daily basis, offering a food delivery service to the den for the cubs and their mom. Male pink foxes are doting and indulgent dads, they usually enjoy playing and roughhousing with their pups, as most dads do. The father stops feeding them as a tactic to get the pups to go away the den. After about three months, though, the cubs expertise a rude awakening: no extra free meals! But he doesn’t make them go chilly turkey, nonetheless-he buries food near the den to help teach them the way to sniff and forage for meals. Just like the puppies of domesticated canine, African wild dog pups are extraordinarily lively and expend quite just a few calories throughout the day. See red foxes with us on our Churchill polar bear trips. Since the pups are unable to eat stable foods till they are about ten weeks previous, their father will swallow their food and then regurgitate the softer model for the pups to eat, ensuring they get sufficient nourishment. Some dad and mom will cease at nothing to ensure their kids have a sq. meal! This feeding apply serves one other function, too-since the pups should rely on their fathers for food, it retains them from wandering too far from residence, in order that they don’t fall prey to enemies. See African wild canine on any of Nat Hab’s Botswana safaris. By two weeks previous, the golden lion tamarin infants are carried on their father’s back nearly 24/7. Dad hands them over to their mother one at a time each two to 3 hours, then she nurses the baby for round 15 minutes and fingers it back to its father. The infants will journey on the father’s back until they are six to seven weeks old. At 4 weeks, the babies begin to eat smooth food, and it’s the father’s job to peel and mash bananas and hand-feed them to his offspring. See golden lion tamarins in the wild on Nat Hab’s Brazil trip extension. Male flamingos are all around good guys. Even while congregating in a flock of thousands of birds, these guys remain monogamous, mating with one special gal for all times. Flamingo dads are also feminists, as they wholeheartedly consider in gender equality, which is rare in the animal kingdom. Once she lays her egg, the father shares in the accountability of incubating the egg, as they take turns sitting on the nest for equal amounts of time. As soon as the hatchling is born, mom and dad share all parenting duties equally. When it comes time to mate, dad helps mother choose a nesting site, and together they construct the nest out of mud. See greater flamingos on considered one of Nat Hab’s Galapagos tours. Collectively, most frog and toad species have some fairly devoted dads. Different amphibian fathers, such because the midwife toad, implant their spawn beneath their skin, normally on their backs of their legs. Some male frogs keep their tadpoles of their mouths till the tadpoles are in a position to make it on their very own. Male seahorses go above and past with regards to parenting-they're certainly one of the only species within the animal kingdom identified for male pregnancy! One type of frog, aptly called the pouched frog, carries their offspring in a pouch on their belly whereas they develop, much like kangaroos or possums do. Seahorse dads could not expertise morning sickness, but they do must endure contractions as they go through labor. That’s proper, the moms deposit their eggs into the male seahorse’s pouch, then he fertilizes and incubates them for forty five days until they are born as full-on tiny seahorses. Emperor penguin dads are weighted teddy a few of the most dedicated animal fathers out there. By the time the feminine lays her egg, she’s expended a lot vitality that her nutritional reserves develop into exhausted, and she should got down to sea for 2 months to feed. Throughout that point, the dad takes on the function of single father and retains the egg heat by ever so rigorously balancing the egg between the highest of his toes and his stomach. He takes his responsibility seriously and doesn’t eat and even transfer throughout your entire two months, for if the egg is exposed to the harsh Antarctic cold and wind, the chick won’t survive. If the chick hatches before mom is again, dad will feed the chick with milk he produces from his esophagus. What dedication! See penguins within the wild on one among Nat Hab’s Antarctica adventure cruises. Warm temperatures and humidity are key to rising polka dot plants. Count on to water commonly until you get adequate rainfall. Polka dot plants bloom sporadically, typically during the summer season, with small lilac or pink-colored flowers on spikes. Pinch off these flower spikes to maintain the plant’s power centered on growing its vibrant foliage. Polka dot plants have become a problematic, aggressive grower in Queensland and New South Wales, Australia. This plant additionally needs regular feeding throughout the spring to fall growing season. Within the U.S., it is not invasive and is safe to plant in-floor. Within the U.S., it isn't invasive and is protected to plant in-ground. Choose a planting site that's not in low light or too much gentle or else you may expect the foliage colors to fade, lessening the plant's ornamental worth. When grown outdoors, polka dot plants like a spot with some shade. Vivid, oblique gentle is good indoors, equivalent to from an east- or south-going through window.

If rooting within the soil, place the contemporary-reduce end of your slicing into potting mix or peat moss and keep it evenly moist. 5. Cowl the chopping with clear plastic wrap till the stem develops leaves or other obvious growth. Optionally, you may place some rooting hormone on the recent-reduce end earlier than planting it about an inch deep in the soil to aid the rooting process. It can take several weeks to several months. 6. To test if the slicing has set roots, gently tug on the chopping to see if it has give outdoor pots or if roots keep the stem rooted within the soil. Only transplant the chopping outside once the menace of frost is gone. 7. The plant's reducing is ready to be repotted once the cutting has established a number of inches of latest development. Place the plant in a sunny location. Sow seeds on the surface of heat, moist soil. The seeds should sprout in just a few days. Only plant outdoors after the risk of frost is over. Once the seedling has grown a number of inches-often in a few weeks-it is able to transplant into a larger container or plant outdoors. Its roots have nowhere to grow. If a plant outgrows its container, it turns into pot sure or root sure. A sure sign your plant has outgrown its pot is when the roots start growing out of the drainage holes. The perfect time to repot a polka dot plant is in the spring after its dormant period. Gradually increase the plant's pot size. Too giant a pot encourages the roots to deal with growing under the soil line, which is not good for the plant's upward growth. Since this plant is a tropical plant, it is not going to survive frosty weather. The brand new pot shouldn't be more than two inches wider and not more than two inches deeper than the old pot.
