 other fish waiting to feed upon the spawn. The result is that out of the 5,006 to 1000 eggs of each fish only a very small proportion ever become fer tilized and aTe allowed to hatch.
 II have blueprint of nay proposed methods for protecting salmon during spawning season. The first represents 8 boom, laid diagonally across small river. To this boom is fastened wire netting of small mesh with heavy chains attached along the lower edge to hold the netting to the bottom of the stream. In this way fence is made that will prevent all fish from passing up tue river.
 Near one osak, and below Che fence, is placed an apparatus to serve the purpose of sorting the salmon from the other smaller fish. This contriv- ance operates, having principle of water wheel, having stwo paddles and two scoops, or aprons. The running water striking against the paddle causes the wheel to turn. The two scoops placed opposite 60 the paddles are made of netting of mesh that will allow the small fish to pass through but will pick up the salmon and slide them over the barrier, where they will at last be free of their enemies and al- lowed to spawn unmolested, as we know that the grayling and other small fish leave these streams in the fall and do not return again until in the spring.
 "It is, therefore, the purpose of this method to have the apparatus in place early enough in the spring to prevent their return to the spawning grounds.
 ''The second method is fence of small mesh netting across stream much the same as in Fig. l. Below this first fence is another one of large mesh netting across therstrsam diag- onailv, at an angie to instead Of par. allel with the first fence. The grayling and other small fish will pass through the first fence, but the salmon, being too large, will be led to, the right and enter the trap shown on the sketch. A gate is here provided in the upstream fence of fine mesh for the passage of the salmon to the waters above, where they will be free of the small fish. At the left of the sketch Is ,showo .A trap formed by two leads of fine mesh net. ting, into which the small fish will be led. A wheel can be used here instead of trap to destroy the small fish.
 'Nn both plans the boom logs will serve as z. foot bridge for convenience of caretakers to cross the stream.
 1T suggest that one of these swo svs- tems be placedein one of 4thev favorable spawning tributaries of each of the large rivers. would also suggest that a trap be placed in Goodnews bay for the destruction of beluga. This bay Is centrally situated between Nushagak and the Yuko1 river.
 ''When the tide is out, the greater part of the area of this bay is mud flats. There are two small channels through these flats that lead to the rivers, and these channels are navigable to small boats. In making the rounds of the rivers on this coast 8 large namber of beluga enter Goodnews bay-probabiy most of them get in here at one time or another. They enter after the tide is well flooded and keep on the flats where they can find the best 6shing. As they near the head Of the bay the fresh water becomes the best fishing ground. and they are thus led into the rivers, which they follow for some dis
