Reading the Man of Signs, or, Farming in the Moon

What did the signs and the phases of the moon mean to moon farmers in the 1840s?

One of the most common printed images of the first half of the nineteenth century was also the one of the most derided—often, treacherously, in its own caption. Right under his woodcut of “The Anatomy”—the image of a male body linked to the signs of the zodiac that began most American almanacs—the almanac-maker David Young wrote sourly in 1848: “It is thought proper to notice in this place, that in this enlightened age of the world, people in general place no confidence in these signs, nor the prognostics of the weather.” In this, as he certainly knew himself, Young was wrong. “There are many men at the present age, so far behind the times,” complained another author, two years before Young’s Almanac “that if they have a tooth to pull, a vein to open, a pig or a calf to castrate, a patch of thistles to mow, a bunch of white birches or scrub oaks to cut down, or a dose of physic to swallow, the chapter of signs must be consulted, and their connection with the body, or the plant ascertained before anything can be done.” At least one of these men, as demonstrated in the margin of the second image on the left, was using my copy of Young’s almanac.

If by the 1840s the Anatomy and the columns of calendrical symbols to which it was keyed had been an embarrassment to American almanac makers for more than a hundred years, they nevertheless still stood as required elements of the agricultural Almanac, the most stable features of a famously volatile and various form. One reason for their persistence was their importance to the practices of “moon farming,” which used astrological information to mark time and schedule agricultural tasks. The astrological tables were, as such, as important as the other (more recognizably utilitarian) forms of information that almanacs provided—critical elements of these objects that rural Americans hung from hooks on the wall, whose ripped pages they repaired with careful stitches, and, as above, whose margins they marked with signs of their own.

To contemporary historians, the first pages of an almanac can be frustrating to work with. It’s tempting to skip to the later sections—rich, if confusing, collections of texts that mingle seasonal poetry, jokes about Irishmen, and stories of canny farmers, with helpful information about circuit court session dates and the “Use of Sulphuric Acid as a Manure.” The first pages, by contrast, consist of the Anatomy, some astronomical calculations, and a twelve-page calendar packed top to bottom with unfamiliar symbols. When students in my classes seem to be identifying too much with seemingly “modern” nineteenth-century farmers, a short almanac “problem set” quickly restores their sense that they’re dealing with a culture alien to them.
