If there was some public concern for the slaves in the fields and some beginnings of legislation on the conditions of employment in the industrial States, there was no thought for the isolated, lean, heavy-fisted farmer of the Southern up-country or the Western prairies. Land was still cheap, crops were increasing in bulk and value every year. Nor did the farmer desire the attentions of society, provided the new railroads were laid through his districts and rates were not too exorbitant. He worked hard for a few months, then rested till harvest time, after which he hunted and fished. During the long cold winters of the Northwest he sat in his chimney corner or tended his cattle. Few thought of fertilizing their land; terracing against rains and floods was almost unknown, and for most farmers plowing was done up and down the hills, which only hastened the washing-away process so characteristic of the Southern agriculture. Very few farmers thought it worth while to rotate their crops when fresh lands were to be had at a few dollars an acre. The area of the United States seemed limitless, and hardly a tenth of its arable land had ever been brought under cultivation. The inventions of 1840-50 enabled the Western farmer to grow larger crops, and harvest time was not so burdensome; corn-shellers and grain-fans shortened the hours of labor for the men. Sewing-machines and the revolving churns from the factories gave some relief to the women, whose round of labor, milking, cooking, cleaning, washing, and attending children, was still almost ceaseless. Even the picnics and barbecues offered little to them, for they must still prepare the great baskets of food and serve their lords and masters while they deliberated on "bleeding Kansas," new railroad schemes, or negro slavery.
