Note 30 — Chapter XVII · MEASUREMENT—Continued
Reading edition
The United States Geological Survey, Washington, D. C., in 1906 published a report on the coal testing plant at the Exposition, St. Louis, Mo., 1904. Part I, Field work, classification of coals, chemical work. Part II, Boiler tests. Part III, Producer-gas, coking, briquetting, and washing tests. This report, with elaborate tables and many illustrations, is of great value.
The Pennsylvania R. R. Co., Philadelphia, in 1905 published a large and handsomely illustrated volume, “Locomotive tests and exhibits, St. Louis, 1904.” $5.00. The locomotives represented the best American practice of 1904. Every detail of construction and operation is given in the most instructive manner.
The Company is continuing these tests of locomotives at Altoona, Pa.
