Corn, which is the staff of life. —EDWARD WINSLOW, Good Newes from New England, (1624)

Inventions—Some New, Some Old

Let us forget, for the moment, white conquerors like Alexander and white gods like Quetzalcoatl. Let us suppose that the Indian actually invented his own culture.

This does not mean that we throw diffusion out of the window; for the Indian may have invented things in the Old World and brought them to the New—which is one kind of diffusion. On the other hand, he may have invented in the Americas the same things that other peoples were inventing—before or after him—in Eurasia. That, of course, is independent invention.

There is a third possibility: that the Indian invented things in the New World which none of the peoples of the Old World ever invented. If he could do this, then it is obvious that he could invent some things which other people had also invented. The Indians ability to invent uniquely is a far stronger argument for independent invention than the theory of “psychic unity.” It is also an argument for early man, if the things invented can be dated far back in time.

NordenskiÖld and others list a number of inventions that are unique to the New World.[1] Among them are the hammock; the tube of diagonally woven fibers which enabled the lowland Indians of South America to squeeze the poison from the manioc and produce wholesome tapioca; the ventilating and cooling system of the kivas (the subterranean religious chambers of the pueblos); the Peruvian whistling jar; the cigar, cigarette, tobacco pipe, cigar holder; the quipu (a set of knotted strings for counting); the enema syringe; the hollow rubber ball; elastic rings; the toboggan; the Maya calendar and hieroglyphs; and possibly the snowshoe. If the list is not very impressive, consider how few unique inventions the Old World could muster in the same kind of stone age.

The significance of the list is reinforced by our knowledge of certain parallel inventions which the Indian is presumed to have made without aid from the Old World. One is metallurgy. In South America, he discovered rather late how to smelt metals and make bronze. This lateness, according to NordenskiÖld, proves independent invention. If migrants brought over the knowledge of metallurgy, they left no trace of it along their journey, either in North America or in the South Seas; and there is no Indian folklore telling of how their forefathers or their gods brought bronze to the New World. NordenskiÖld makes the further point that, having invented the casting of metal, the Indians must also have invented the forms in which they cast it—the socketed ax, for example, the bell, and the pincers. On the basis of these inventions in metallurgy, and other inventions, NordenskiÖld writes, “It is surely a matter of logical reasoning to suppose that independent inventions may have been made by them in the realms of architecture, weaving, ceramics, etc.”[2] This would be a very much better argument, of course, if bronze had never been invented in the Old World. Then no boatload of Alexandrians could ever refute it.

NordenskiÖld might have added agriculture to his list of unique Indian inventions—or rather the products of agriculture. The Indian discovered and cultivated plants unknown to the Old World. He developed special varieties suited to special conditions of soil and climate. In a sense he even invented one very important plant, for botanists have been unable to find any wild ancestor of Indian corn.

American Plants and Their Cultivation

The list of important plants that made up the Indian’s agriculture is impressive. It is also unique, for it contains few Old World species. In the northeastern United States there were a few wild fruits and berries—grapes and blackberries, for example—that are common to the north temperate zones of both hemispheres. In Middle America were two plants which are found in Asia and the South Sea Islands—the bottle gourd and the coconut palm—and cotton of a different species from that of Eurasia and Africa. Otherwise, “of cultivable plants,” says NordenskiÖld, “the ancient American higher civilizations possessed none in common with the Old World.”[3]

There are two very curious facts about primitive husbandry in the New World. The Americas provided the Indian with few animals that could be domesticated, and no draft animals at all. Because he had no ox and no horse, he could not use a plow, and did not invent one. Fortunately, on the other hand, the Americas had no plants that required plow cultivation and field sowing. Wild rice grew in lakes. The rest of the plants responded to hoe culture. Or, rather, since the Indian used the hoe only in limited areas—and probably quite late, at that—the seeds could be placed in the ground with a planting stick, and after a little hand cultivation the shade of the abundant leaves would take care of the weeds. Beans, corn, manioc, and potatoes—the four major crops—were ideally suited to the only means the Indian possessed for planting and cultivating.

This difference between agriculture in the Mediterranean area and the New World is quite as great as the difference between the pastoral activities of the Fertile Crescent and the scanty domestication of animals in the Americas. Here there is no solace for the diffusionist. As Lowie has said, “There is more resemblance between the Ionic capital and a Papuan headrest than between the sowing of cereals and the planting of a banana shoot.” (If he had been thinking specifically of our present problem, he would have substituted corn kernel or potato eye for banana shoot.) “Bee-keeping is not the same as training elephants or herding horses; and sowing seeds is not equivalent to planting a side-shoot or a tuber, let alone ridding a tuber [manioc] of its prussic acid.”[4]

When and Where Did Our Agriculture Begin?

There are two questions to be asked about agriculture in the New World: Where did it originate and with what plants? Did it have a multiple origin—which would entail a sort of independent invention? These questions have a bearing on how much time man spent in the inventing and perfecting of agriculture, and therefore on how long he had been thoroughly settled in the Americas when the Spaniards came.

Not so many years ago, Indian corn, or maize, was carelessly considered the first plant cultivated in the Americas—probably because it was the most spectacular—and was supposed to have originated in the highlands of Mexico or Guatemala. Now we know that pumpkins preceded corn, and so, in all probability, did most of the commoner food plants. Beans and melons, with their free-running vines and prominent flowers and seed pods, would seem most likely to have first attracted man—or, perhaps, woman—and led him to assist the processes of nature.

When corn was king, semiarid farm lands were supposed to be the place of its origin. Spinden saw “irrigation as an invention which accounts for the very origin of agriculture itself.”[5] Semiarid land, however, is notoriously hard to clear; though its plants are few, they have deep, tenacious roots. River flood plains of the Sonoran desert in Mexico—ideal by Spinden’s standard—yield no evidence of long or extensive occupation, according to Carl Sauer. Where irrigation was used in our Southwest, dates are not early. The evidence of the plants themselves, he writes, “overwhelmingly points not to desert or steppe but to several humid climates for their origin.”[6]

There has never been much enthusiasm for the humid tropic lowlands as the seedbed of agriculture. Of late years the students of botany have turned to the temperate forest area and particularly to the mountain valley as the seat of agriculture. This has been championed by N. I. Vavilov and a group of Russian scientists, sent to the Americas in the 1920’s, who made a most elaborate study of our native cultivated plants. Much of their evidence is too technical for presentation here, but their conclusions have seemed convincing to many students.[7] A mountain valley provides a wider range of temperature and rainfall and a greater variety of native plants. Its forest trees, before they are cleared by girdling and burning, store up a rich humus under their shade. Costa Rica and El Salvador—full of isolated mountain valleys—contain, according to Henry J. Bruman, as many species of plants as the United States, in spite of the fact that the United States is a hundred times the size of the two countries together.[8] The Russians believe that agriculture took early shape in certain mountain valley areas, including southern Mexico, Central America, Colombia, highland Peru, western Bolivia, and southern Chile. Though they do not commit themselves as to whether agriculture originated in one place and spread later to others, “their evidence,” Sauer thinks, “may be interpreted in favor of multiple independent beginnings.”[9] But Bruman, writing of their work, points out that the “enormous spread of maize and beans, of cotton and tobacco, for example, shows that there is ‘something of the undivided whole’ in the great cultures of the New World, as Vavilov well expresses it.”[10] Richard S. MacNeish, an archaeologist who spent at least a dozen years on the matter, declared in 1960, “There were multiple origins of New World domesticated plants, at different times.”[11]

It is amusing to note that the diffusionists and the partisans of independent invention change places on the subject of corn. Spinden diffuses all corn from Middle America. Gladwin plumps for various areas of independent invention, including the Mississippi Valley.[12]

The Indian’s Accomplishment in Agriculture

There can be no argument over the remarkable nature of certain things that the Indian farmer accomplished. Through long cultivation he produced the seedless pineapple. When he found that one form of manioc was poisonous, he took thought and devised a press for squeezing out the deadly cyanide while retaining the starch. Bruman calls this “one of the outstanding accomplishments of the American Indian.”[13] He says further:

The original process of plant selection seems to have been carried on more intensively in the Americas than elsewhere. The major crop plants were farther removed from their wild ancestors than those of any other part of the earth at the time of the discovery. Mention need only be made of corn, which is so distinct as to require classification in a unique genus, and of the potato, which resulted probably from the crossing of many and various Solanaceae.

[The Solanaceae include nightshade, jimson weed, tobacco, and others.] It is ironic that, as O. F. Cook has observed, the white potatoes grown each year are worth more than all the gold that the Spaniards took from the Incas.[14] This is probably still truer of Indian corn.
