A 1909 magazine article arguing that oak-feeding wild silkworms from China and Japan could be raised commercially in the United States. It describes the Chinese tasar (Antheraea pernyi) and Japanese yamamai moths, their semi-domesticated rearing on scrub oak, and the pongee made from their silk. The author cites Chinese wild silk exports and his own successful rearing of yamamai on American red and scarlet oaks, and reasons that low labor needs and absence of natural enemies would make a venture pay. Illustrated with photos of a cocoon, a moth and a caterpillar.
