Method and Cost of Mining the Thick Freeport Coal in a Second Western Pennsylvania Mine

From introduction: The purpose of this paper is to present a detailed description of the methods employed and the equipment used, with the results obtained in the operation of this mine in the thick Freeport bed on the northern end of the field, near the Alleghegny-Butler county line in western Pennsylvania. It may be classed as a captive mine, as the largest portion of the product is consumed at the by-product plants of the parent company

The Soft Red Winter Wheats (open access)

The Soft Red Winter Wheats

"At least 66 distinct varieties of soft red winter wheat, known by nearly 400 different names, are grown commercially in the United States, and additional varieties are grown experimentally. These varieties differ widely in yield, adaptation, milling and baking value, and other characteristics. The most widely grown varieties in the United States in order of importance are Fultz, Fulcaster, Mediterranean, Poole, Red May, Red Wave, and Harvest Queen. The area of each of these varieties in 1919 varied from about 4,800,000 acres to about 1,000,000 acres." -- p. 2

Beekeeping in the Clover Region

"Beekeeping methods suitable for the clover region are well developed but many beekeepers of this region are failing to obtain the full available honey crop because of deficiencies in their practice. A system of management is here given which will result in a full crop from these sources. The variation in the value of the clovers to the beekeeper is also discussed and the methods to be followed in bringing the clover region back to its former prominence in honey production are outlined." -- p. 2

Beekeeping in the Buckwheat Region

"The production of the full honey crop from buckwheat requires a plan of apiary management quite different from that of most other beekeeping regions. A system of management is here given which will result in a full honey crop and at the same time control European foulbrood, which is so prevalent in the buckwheat region. Methods are also given which may be used in case the clovers are valuable as sources of nectar." -- p. 2

Beekeeping in the Tulip-Tree Region

"Many thousand colonies of bees occur in the region where the tulip-tree is abundant but the honey crop from tulip-tree flowers inconsiderable. Too few beekeepers in this region have modern equipment, it is true, but the greatest loss comes from the fact that they do not care for their bees so as to have them ready to gather the abundant nectar from this early-blooming tree. In this bulletin a methods is given for the management of the apiary so that the full honey crop from this source may be obtained." -- p. 2

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France

From Introduction: "Coal dust as an agent of widespread explosions had been under suspicion, and watering to allay the dust was recommended by some mining engineers but the watering of coal-mine dust was adopted in comparatively few mines of the United States and Great Britain, and had not been introduced widely in any country except Germany. Rock dusting, another method of preventing explosions of coal dust, was early tested with success by the Bureau of Mines in its first gallery at Pittsburgh and, beginning in 1911, at the experimental mine, Bruceton, Pa."

From Preface: "The writer began testing the rock-dusting method for the Bureau of Mines at the Pittsburgh gallery in 1909, and later continued such testing in the bureau's experimental mine, with favorable results. Beginning in 1911 the bureau issued reports recommending rock dusting as alternative to watering."

The entire body of mining laws is set out for these obvious reasons: (1) To show the progress and advancement made, and the changes through which the enactments have passed; (2) an author may not assume the determination of what particular laws are in fact in effect, as this is within the jurisdiction of the courts alone; (3) it was at least necessary to set out all acts that had at any time been construed by the courts."

Regulation of Explosives in the United States: with Especial Reference to the Administration of the Explosives Act of October 6, 1917, by the Bureau of Mines

From Origin of Federal Explosives Act, October 6, 1917: " A competent force from the Bureau of Mines was then assigned to study the laws and ordinances of countries, States, and municipalities in which lawas and ordinances regulating explosives have been enacted, and especially to ascertain how these laws had been modified by the necessities of the existing state of war, and, also, wherein the proposed law might conflict with or overlap the jurisdiction of existing laws. This incomplete enumeration of the peace-time uses of explosives shows that the quantity consumed is large. A more definite conception is given by the following statistics of production, to which is added statistics for exportation that disclose something of the effect of war on the explosives industry."
