Book excerpt: Excerpt from An Engineering Study of the Coals on the Chicago Market The samples of coal for analysis were very kindly presented to the writer by the City Vuel Co., since purchased by the Peabody Coal Co., whose yards are located at Wentworth Avenue and 4oth Street., Chicago. The samples were takeh from the different coal piles around the yards one warm day in February and were quite wet from.the melted snow so that it was thought advisable to allow them to stand for a couple of Weeks before grinding for analysis, in order that any undue moisture Which might have been absorbed by the coal during its exposure to the snow and water, might dry out normally. Although it is preferable to take large samples and quarter them down to the amount desired for analysis, it was not done in this case owing to lack of working and storage space. However, two or three small lumps having as near the average composition of the pile as c uld be told by inspection, were taken, and the state and district from which each.coal came noted. The most of the sawples taken came from Illinois, Pennsylvania and West Virginia, in Which states, by the way, the largest share of the coal of t the United States is mined. In 1900, Pennsylvania ranked first in coal production, Illinois second, and West Virginia third. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
