Captain Layson has written non-fiction, some good (Fighting Crime- 1948, p. 282) and some dull (Wings Around the Worlds 1948, p. 25). These explanations of some of our machines and how they work are pithy, but they seem to have gone completely ungrammatical. Information about guns- rifles, shotguns, revolvers; atomic powered submarines and atomic energy in general (there is a lot about the Columbia River plant); television; locks and locking devices; hydraulic transmission for cars; weather instruments and even the phonograph- is in good quantity. But split infinitives, dangling participles, ambiguous dependent clauses and generally lame sentences must be chewed before tasting the facts. Perhaps the gristly grammar won't daunt the interested.
