   • 1864, Edmund Morris, “Chapter VI: Planting a peach orchard. How to preserve peach-trees”, in Ten Acres Enough: A Practical Experience Showing How a Very Small Farm May be Made to Keep a Very Large Family, With Extensive and Profitable Experience in the Cultivation of the Smaller Fruits‎, New York: James Miller, page 42:

     Then I purchased ploughs, including a subsoiler, a harrow, cultivator, and other tools. One acre of the whole was in clover, another was set aside as being occupied by the dwelling-house, garden, stable, and barnyard; but much the larger half of that acre was allowed for garden purposes. This left me just nine acres for general fruit and vegetable culture. I hired a man to plough them up, he finding his own team, and another to follow him in the furrow with my subsoiler. The first went down ten inches, and the latter ten more.
