“Our potato-digger is almost perfect too. With it two or three persons and an engine can dig more than a thousand bushels a day. The digger is made something like this: A kind of incline plane plow runs under through the row, raises the soil and potatoes on the plow, which drops the whole on a wire elevator which lets the soil pass through it, and elevates the potatoes in a car back of the plows. In this manner one engine draws from two to four plows. “Hay and other feed for cattle is not much needed; for as I have told you, we keep cattle only for dairy purposes, sheep for wool and poultry for eggs. The stock is raised on land not so well adapted for agriculture. The feed is nutritious and well prepared; the stabling is all of the very best and most convenient kind, warmed by electricity. The hay is cut with large mowers, which elevate the cut grass into the large wagon racks used with the headers. It is cured by artificial means the same as the grain. “By this method we have always first-class hay highly nutritious. None of it is left on the field. None of it blows away; no waste, and not a particle of it is spoiled by rain, because it is always hauled in and cured as fast as it is cut. “I notice that your method of hay-making is very slow, uncertain and wasteful, because much of it is totally spoiled by rain before it is stacked; a part of it is spoiled in the stack, and a large part of the remainder is more or less damaged in various ways. “I may say here that our poultry is all hatched by steam incubators, and is as well housed as we are ourselves. In the winter we have large areas covered with glass, under which they enjoy the warm sunshine and even temperature almost the same as in the summer. By these means we get abundance of eggs during the whole year.
