I little thought when I left my farm yards, horses and cattle in the care of other men, and began to write, that I should spend nearly all the winter of 1875 in writing; much less, that I should offer the product of such labor to the public, in the Centennial Year. But I have been urged to do so by many friends, both learned and unlearned, who have read the manuscript, or listened to parts of it. They think the work, although written by a farmer, should see the light and live for the information of others.
