Two luid one-half of the king salmou arc equivalent to the same amount. Kach cannery has hitherto maintained from one to five traps for capturing salmon, but the yield by this means has not warranted the expense of keeping tiicni in repair. The main body of the trap is made of twine, but the leaders are constructed of galvanized wire netting, which is better adapted tjo withstand the pressure of drift material brought down by the current. N^otwithstanding every i)ret'-aution, howovcir, t'.iey are frequently swept away. Gill nets have now been adopted by all the canneries, as ailbrding the best results. Two sizes are in use. The one for king salmon measures 100 fathoms long by 2^^ feet deep, and has a 9J-inch mesh; the other, for red and silver salmon, is 70 fathoms long by 13 feet deep, and has a G^-iuch mesh. They seldom last more than a single season, as they are subject to very hard usage. The salmon are sometimes most abundant a considerable distance above the canneries, or from 40 to 50 miles from the mouth of the river. At such times the fish- ermen are carried to the fishing-grounds, where they live on board of tlie scow lighters ordinarily employed for discharging and loading vessels, a stea<m launch beiu|^ used to tow the latter.
