The ability of agriculture to smooth out the seasonal scarcities of wild foodstuffs had major consequences for the sizes of Native American populations in New England, The nonagricultural Native Americans of Maine sustained population densities, on average, of perhaps 41 persons per 100 square miles. the crop-raising native Americans, on the other hand, probably maintained 287 persons on an identical amount of land, a sevenfold difference. When these two broad groups were combined, the total Native American population of New England probably numbered somewhere between 70,000 and 100,000 people in 1600, ( Lest this seem unimpressive, one should remember that the English population of New England was smaller than this even at the beginning of the eighteenth century, having reached only 93,000 people by 1700.) the crucial role of agriculture in maintaining so large a Native American population in pre colonial New England is clear. although agricultural and nonagricultural peoples inhabited roughly equal areas of southern and northern New England, respectively, those who raised crops contributed over 80 percent of the total population.
