In this comic it is made clear that Randall did know that it is possible to have a well on top of a hill, as he has drawn just one of these in the second image. Alas, that hill was San Juan Hill, And gruesome was the slaughter. Jack and Jill went up a hill To fetch a pail of water. Randall has previously composed another version of this poem, which was by mistake published in Five-Minute Comics: Part 4. Also, fracking may cause induced seismicity in the form of microearthquakes, as alluded to in the title text, which is the cause for tumbling down in the title text version. But in the comic, fracking at the bottom forces the water up, thus explaining why the kids go get water up the hill, which, as Megan points out, is messed-up hydrology. Thus water is usually found at the bottom of valleys or hills. This goes against the usual laws of hydraulics, themselves subject to the laws of gravity, which indicate that water should go down through ground cracks. In this comic, water can now be found at the top of the hill. The liquid used for fracturing usually also contains materials like sand or ceramics which, once the liquid is removed, will help to maintain the newly formed cracks so as to further allow the desired free movement of oil and gas.Ī common side effect of this method is that water levels and presence at the surface might be modified. This allows potential gas and oil to flow more freely. With enough pressure, the stratum starts to deform and crack. In these methods, highly pressurized liquids are forced into a given ground stratum (or layer). This version, which may explain why they went up the hill after water, connects the idea to hydraulic fracturing (colloquially "fracking") methods for oil and gas extraction. But fractures make the bedrock shake and Jack came tumbling down. The title text is Randall's own version, a parody of this first verse, where the names have been switched in the first and last line: Alternatively, the nursery rhyme may refer to a dew pond (which is more likely to be at the peak than a well), another concept that Megan would not be familiar with, having not grown up in the English countryside. This all said, the predominance of drawing Jack's and Jill's well at the peak, which is not the best place to put the well, makes Megan's (and Randall's) comment understandable. ![]() As an urban dweller, Megan probably gets water from city plumbing, and is not familiar with the principles of well placement that Jack and Jill grew up with. (This principle explains why water towers are used, even in cities.) Finally, artesian wells deliver water from confined aquifers, which can sometimes be as close to the surface at higher elevations as at lower ones. ![]() Moreover, since it takes more energy to bring water uphill from a well (especially in a pail), there is a long-term advantage to having wells higher than main residential areas, as opposed to lower. In times when populations were more predominantly rural, and probably when the poem was composed, "Always dig your well uphill from the outhouse" was a well-known maxim. However, Megan is probably not aware that since groundwater tends to flow in a similar direction to the slope of the land, it is often considered safer to dig a well uphill from potential sources of runoff, such as outhouses, fields, or septic systems. The groundwater table stays at about the same level over smaller areas, so building a well on a hill would require digging further. Similarly, if the water is coming from a well, then building a well at the top of a hill seems an odd choice to Megan. Thus it shouldn't be necessary to have to go up a hill to get water. The comic makes fun of the counterintuitive idea that Jack and Jill go up a hill to fetch water, because natural water sources like rivers and streams flow downhill, making them usually found in valleys rather than on top of hills. Jack fell down and broke his crown, And Jill came tumbling after. Jack and Jill went up the hill To fetch a pail of water. The first and most commonly known verse is the one referenced by Jill in the comic as she says the first three lines: The rhyme dates back at least to the 18th century, one version even with 15 stanzas. " Jack and Jill" is a traditional English nursery rhyme. But fractures make / the bedrock shake / and Jack came tumbling down. Title text: Jill and Jack / began to frack.
