"Great American Desert", but they also found that the very harsh climate—with tornadoes, blizzards, drought, hail, floods and grasshoppers—made for the high risk of a ruined crop. Many early settlers were financially ruined, and especially in the early 1890s, either protested through the Populist movement or went back east. In the 20th century, crop insurance, new conservation techniques, and large-scale federal aid have lowered the risk. Immigrants, especially Germans and their children, comprised the largest element of settlers after 1860; they were attracted by the good soil, low priced lands from the railroad companies, and (if they were American citizens) the chance to homestead and receive title to the land at no cost from the federal government. The problem of blowing dust came not because farmers grew too much wheat, but because the rainfall was too little to grow enough wheat to keep the topsoil from blowing away. In the 1930s techniques and technologies of soil conservation, most of which had been available but ignored before the Dust Bowl conditions began, were promoted by the Soil Conservation Service (SCS) of the US Department of Agriculture, so that, with cooperation from the weather, soil condition was much improved by 1940. Farm life On the Great Plains very few single men attempted to operate a farm or ranch; farmers clearly understood the need for a hard-working wife, and numerous children, to handle the many chores, including child-rearing, feeding and clothing the family, managing the housework, feeding the hired hands, and, especially after the 1930s, handling the paperwork and financial details. During the early years of settlement in the late 19th century, farm women played an integral role in assuring family survival by working outdoors. After a generation or so, women increasingly left the fields, thus redefining their roles within the family. New conveniences such as sewing and washing machines encouraged women to turn to domestic roles. The scientific housekeeping movement was promoted across the land by the media and government extension agents, as well as county fairs which featured achievements in home cookery and canning, advice columns for women in the farm papers, and home economics courses in the schools. Although the eastern image of farm life on the prairies emphasizes the isolation of the lonely farmer and farm life, in reality rural folk created a rich social life for themselves. They often sponsored activities that combined work, food, and entertainment such
