“We wish to impress upon the minds of those who wish to re-stock our streams with an abundance of good fish, that they must keep the streams clean and pure, if they expect to succeed. It is true that salmon and other fish have been banished from rivers and creeks in which they once abounded, but this was not owing to the great depredations of fishermen, as has generally been supposed. The erection of saw mills on creeks and rivers destroyed the spawn of both salmon and trout, and it has been found that the former fish have been banished from all rivers on which chemical works have been established. They love clear running streams of water—they are sensible fish.”
