It has been the aim of the author to give reliable information free from minute details and technicalities. That information has been, for the most part, gathered through personal experience in_ithe mines. Literature of this special subject is very meagre, and the author is unable to acknowledge any real indebtedness to more than half a dozen volumes. First among these is the valuable treatise on Coal Mining, by H. M. Chance of the Pennsylvania Geological Survey. Other volumes from which the author has derived considerable information are the State geological reports of Pennsylvania, the mine in.

It is the best indorsement that could be given that its work was intelligently, faithfully and sincerely performed. Just what the fate of this bill will be in the Senate 1 am unable to say, but this I do know, and firmly believe, if it fails to pass, it will not be by reason of any failure on the part of the committee to do its duty.

This book was released on 2017-10-28 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Forestry and Coal Mining Until within comparatively recent years the prevailing practice in the lumber industry has been to organize an operation on a period basis; to con struct a plant of a capacity to utilize the amount of timber within a specified period of years; and to finance the operation so that when the last tree is cut the total investment will be liquidated. The plant, then, and the cut-over land have only a sal vage value. The land often must be abandoned. A Sustained Yield plan of operation recognizes the fact that timber grows; that with proper care in logging and protection the land will continuously produce successive new crops of timber indefinitely. The investment, then, in plant and land becomes permanent; it does not have to be written off at the end of a specified term of years; both plant and land continue to be productive and valuable. The forestry department of the Corporation is operated on a Sustained Yield basis. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
