Grain Farming in the Corn Belt with Live Stock as a Side Line

Description: "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.

Sweet Clover on Corn Belt Farms

Description: "Sweet clover is now grown successfully on many farms in the corn belt, both in rotation and as a catch crop to be plowed under. It has proved excellent for hay and pasture, and is unequaled by any other legume for soil improvement. Sweet clover may be used to good advantage for silage, and on some farms, with proper management, it is a profitable seed crop. Mixed with bluegrass, it makes a pasture of nearly double the carrying capacity of bluegrass alone. The object of this bulletin is to present details of management and of the more important farm practices followed on some of the successful corn-belt farms on which sweet clover is grown as one of the principal crops of the rotation. Cropping systems are outlined for farms of different types, and special attention is called to the three essentials of success in growing the crop -- lime, inoculation, and scarified seed." -- p. 2

Coal-Mine Accidents in the United States and Foreign Countries

Description: 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."

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

Description: From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies.

Adjusting Corn Belt Farming to Meet Corn-Borer Conditions

Description: "The European corn borer is recognized as a dangerous enemy of the corn crop.... Its eradication is considered economically impossible but it is believed that the injury may be kept at a point so low that little commercial damage will occur during normal seasons. This can be done by using control measures and practices that have proved to be effective.... On some farms some changes in the crops grown and in their sequence will aid materially in controlling the borer and may prove profitable even when borers are not present. The control program for the individual farm should be given consideration at once in order to avoid sudden disturbance of the organization and operation of the farm when control measures do become inevitable. The necessity of concerted effort by all producers in an infested district becomes evident when the life habits of the borer are considered." -- p. ii
