Louis Clyde Gale, The Golden Hamster Manual (1949)
“ Even though one’s hamstery may be a hobby, he prefers that it may operate at a profit. Thus, each money-saving or money-producing idea has real value. The hamster is still comparatively new to wide and general usage. While a steady stream of laboratory markets is opening, the stream is not a flood but a gradually increasing flow. The bang and boom are only in commercial advertising, and those who fall for such may "go boom.”" Nevertheless, a conservative investment in hamsters, wisely handled, may bring highly satisfactory returns. ”
