A. R. Harding, Fox Trapping: A Book of Instruction Telling How to Trap…
“ In the rapid development of the country the steel trap has played a wonderful part. They have subdued the monster bear and have as well caught millions of the small fur bearing animals, adding largely to the annual income of the hardy trapper. Steel traps have been in use for more than fifty years, but for many years after they were invented they were so expensive that they were not generally used. Of late years they have become cheaper and their use has become general. ”
