"The principle objects in undertaking this study [of farming practices in Washington, Oregon, and Idaho] were (1) to ascertain what methods of tillage are in actual use by the farmers of the region, together with the relative merits of the different methods, and (2) to determine, if possible, the localities and conditions under which each of the leading varieties of wheat succeeds best." -- p. 7

"In keeping with the great progress made in agriculture within recent years the methods employed in hop production have not remained unchanged. Nevertheless certain practical principles of great importance to successful hop growing merit a much wider consideration and use than they now enjoy. These will be discussed in the following pages in which is also presented a brief general outline of hop culture." -- p. 7. Hops culture is discussed with regard to climate and soil requirements, propagation, planting, trellises and training, picking, and curing.
