From time to time the question of shearing or vertical cutting of rooms and entries especially as an adjunct to the usual horizontal cuts, has cropped up in the literature of coal mining and in the discussions of mining men. Exact and definite data based an thorough tests have usually been lacking however and the present article is written to supply as far as possible this deficiency. The tests given below were made over a period of 90 days in the summer of 1921 and the object was to investigate the general .economics, if any, that might result from the introduction of vertical cutting as a standard practice into the Clear Creek mines. The machine used was the Oldroyd Universal coal cutter and comparative tests were made against the Goodman Straight- face machine and the 35 B Jeffrey Shortwall. The tests however should be held to apply only to the various methods of cutting and not as a study in the relative merits of the various machines. The first series of tests were made in the 2nd East district of No. 3 mine, where only entries were being driven at the time, the tests therefore cover only entry work. The presumption was that the entry width would be 12 feet but the oxerrun in some cases was marked enough to make the work comparable to rooms. The first test made was to determine the time necessary to shear as well as cut the places, and the results were reduced to the time necessary to cut a ton of coal. The time for shearing in the table includes the time necessary to revolve the cutter bar to the vertical position.

The Wednesday morning session was called to order by President Lewis at 9:00 am, He called on Bob Wilson to conduct the business meeting. In the absence of any of the Auditing Committee, the treasurer's report, which had previously been examined by them was read. He asked for a motion of approval. It was made, granted and approved. The Resolution Committee was called on to make its report. Mr. Shirl McArthur read the following report: (1) "WHEREAS, the Pneumoconiosis or Black Lung provisions of the Federal Coal Mine Health and Safety Act which have been construed and administered largely as a welfare program rather than as just compensation for occupational disease has resulted in enormous expenditures and commitments from the Federal Treasury, WHEREAS, the imposition of the full cost of future welfare oriented black lung awards on coal operators without regard to workmen's compensation standards and without due process in granting benefits is grossly unfair and discriminatory to the coal operator and places an undue burden on the present cost of coal,

The thought and practices in the field of accounting in the past two or three years are undergoing far-reaching changes, but more important than this is the changing viewpoint of business managers toward accounting reports and statistics. Accounting is no longer considered a necessary burden of business, for progressive managers and operating officials everywhere look upon it as a service. A service of supplying operating men and executives with information on their affairs which enables closer and more effective supervision, to the end that business may be conducted more satisfactorily and more profitably. This service is the real function of accounting in business management. Of the many treatises on accounting published in recent years, the great majority deal with principles and procedures, and were written purely from the accountant's point of view, thus they appeal, and are of interest, chiefly to accountants. Recently, however, the interest displayed by the operating man, be he president, general manager, superintendent, mine foreman or potential mine executive, calls upon the accounting department to serve him in furnishing him with figures showing the financial position and economic progress daily. In order to effectively render this service the necessary co-operation between management, operating and accounting -forces must exist. Satisfactory services may be developed only on a basis of close contact and pulling together between these departments. It is not a one-man job, the responsibilities necessarily rest on all. This co-operation contemplates:

The Alamo Mine The Alamo mine is located about seventeen miles northwest of Walsenburg, Colorado, on the Loma Branch of the Denver and Rio Grande Western railroad, in the foothills of the Black Mountains of Huerfano County. Prospecting Mr. W. B. Lewis of New York City, president of the Oakdale Coal Company and also president of the Alamo Coal Company first became interested in this property in 1920. After all natural features of the surface had been carefully examined by Mr. Lewis, he was convinced that the property was underlaid with coal seams. Plans for prospect drilling were made at once and this drilling was started late in 1921. In all, eight drill holes were put down to the Trinidad sandstone which underlies the coal measures in this field. These drill holes in general, showed very satisfactory results. Two workable coal seams were penetrated by most of these drill holes, the upper seam being six and one half feet thick and the lower seam having a thickness of ten and one-half feet. The two seams are separated by forty feet of sandstone and shale. Analyses of the seams proved each to be of a very high grade bituminous coal possessing hardness much above other bituminous coals, and having very bright lustrous appearance. Tests of more than a year's duration proved the coal to store excellently in closed bins and also in open bins where coal is exposed to elements. The drill hole data further showed the coal seams to pitch more than fifty per cent or about twenty-six and one-half degrees. The pitch direction being approximately South 65 degrees East. The drill holes further proved the coal seams did not outcrop at any point on the property, and no evidence of coal outcrop has been found in near vicinity. A splitting and pinching out of seams was found to occur some two hundred to three hundred feet of theoretical outcrop at very Western boundary of property. The most Easterly or No. 6 drill hole has a depth of eight hundred fifty feet to floor of lower coal seam. The Trinidad sandstone was found to be immediately under the lower coal seam, and the Pierre shales lying under this sandstone. Plans for Development and Sinking Having obtained sufficient data, plans for development of the property were carefully made sometime in advance of the actual opening of the mine. Every condition was carefully studied and the maximum production of clean and well prepared coal at as low a cost as possible during the entire life of mine was kept uppermost in the minds of all. The life of mine is estimated at approximately fifty years. It was decided to open up the lower and thicker seam first, and due to the pitch and other conditions a slope opening was decided upon for its extraction. The pitch of the coal having been found to be from fifty to sixty per cent or twenty-six to thirty degrees, the plan of driving the slope directly down the pitch of seam was eliminated and a plan that would give a more economical grade was decided upon. To obtain a lesser grade, a point several hundred feet west of-and at a less elevation than the theoretical outcrop of coal seam was selected for the slope opening. (Fig. 18.) To have driven directly down the pitch of coal seam would also have given the slope an uneven grade as the pitch of coal seam varied as it approached the crop. From this point of opening, the slope was to be driven on a thirty-one per cent, or' about seventeen degree pitch to intersect coal seam in No. 6 drill hole, a distance through the Pierre shales and Trinidad sandstone of two thousand five hundred fifty feet, the slope to be driven practically due East
