"This bulletin is written to suggest to the corn-belt farmer of the Middle West -- especially the farmer whose soil has been run down by continuous grain farming -- some ways of coordinating and 'cashing in' the scientific advice offered him in hundreds of bulletins already published.... Briefly, these are the conclusions reached by our most successful corn-belt farmer and agricultural experts: To make a money-maker of a farm that has become a losing proposition through steady grain farming you must in addition to raising standard grain crops -- (1) Grow legumes, (2) Raise live stock as a side line, (3) Keep accounts of receipts and expenditures, (4) Mix horse sense with scientific agriculture, (5) Try to secure enough capital to enable you to farm right, (6) Stick to whatever policy you adopt long enough to try it out, and (7) Confer with your County Agent and make a careful study of the bulletins of the United States Department of Agriculture." -- p. 1-3.

From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."
