A detailed and mathematically elaborate promotional for irrigation construction by the California Corrugated Culvert Company. The booklet chiefly advertises various types of "Armco" flumes manufactured by the company, and includes numerous photographic reproductions, illustrations, and blueprints, as well as complex tables and mathematical formulae that testify to the safe, quick, and efficient movement of water by these structures. The complexity of some of the math printed here suggests that the pamphlet was aimed at engineers and other highly-educated employees of irrigation projects in California. OCLC locates five copies in U.S. institutions.
