Not illustrated. 1888 edition. Excerpt: ...they never see them swimming down-stream. Except for short spurts of about 30 yards the salmon is always seen with his head up-stream. An interesting fact observed by Mr. G. W. Williams would seem to indicate that these fish go down-stream, floating with the current, with head pointed up-stream. He observed that the young salmon proceeded down the river to the sea invariably with heads up-stream. Hon. L. T. Barin has also observed that a hooked salmon will take spurts down-stream for a distance of not more than 30 yards, after which it will turn and make its long runs up the stream. These facts tend to show that all salmon go down the river with heads generally pointed up-stream; that owing to some peculiarity of structure they can not swim for any distance with a strong current, but are obliged to float down with it. Hence it does not follow necessarily that a salmon seen with head up stream is on his way up the stream. The question as to whether the salmon returns from the spawning-grounds or dies there is one of great importance and interest. If all, or nearly all, die, then there can be no objection to the catching of most of them, provided that artificial means are adopted for placing in the rivers each year a.sufficient number of young fish to insure a good run four years thereafter, and this can be done with precision. It becomes necessary, then, to believe that the salmon of the Columbia River only spawn once on arriving at maturity. But Chinook salmon with fully-matured spawn are caught in sizes ranging from 2 pounds up to 60 pounds in weight.
