Windmills for Irrigation, Water-Supply and Irrigation Papers of the United States Geological Survey No. 8, originally published by the United States Geological Survey, Department of the Interior (Government Printing Office, Washington, D.C.), 1897. Reprinted in 2004 by Nation Builder Books, Leesburg, VA. 5½ x 8½ softcover, 49 pages plus eight plates of black & white photos.
This is one of the primary sources in all histories of American windmills. It is an exhaustive comparison of some of the leading windmill makes of the day, chock full of statistics and charts. The basic measure on which each windmill is judged is strokes per pump per velocity of wind. It is amazing to see how differently the various windmills performed over the range of wind speeds from five to thirty miles per hour.
