102 REPORT OF THE COMMISSIONER OF FISHERIES. 
Unless trained men familiar with fishes and fishery gear, methods, and 
products are placed in charge of this work the office of fishery inspector 
should be abolished. 
7. Power should be given to the Secretary of Commerce and Labor 
to make, as occasion requires, such minor regulations as may be 
deemed necessary for the good of the industry, including the closing 
of streams and lakes and of their approaches, these regulations to be 
made on full consideration of the various ways in which different 
fisheries may be affected. 
In justice to the fishing interests of Alaska it is important that all 
these matters receive early consideration. All necessary legislation 
and regulations should be perfected and promulgated as soon as pos- 
sible, so that the canning companies may know the conditions under 
which the fisheries are to be carried on next season and make their 
plans accordingly. 
THE COD FISHERIES OF THE SHUMAGIN ISLANDS. 
Representations having been made to the Bureau that the cod fish- 
eries centering at the Shumagin Islands were becoming depleted, those 
islands were visited by the Alaska salmon commission and inquiries 
made concerning the condition of the fishery. It was found that the 
difficulty of securing remunerative fares is increasing year by year. 
Until recently an abundance of fish was found in the immediate vicinity 
of the islands, but now the fishermen are compelled to go much greater 
distances and the fish average smaller than formerly. It is believed 
by the special commission that the establishment of a cod hatchery at 
Sand Point, Pirate Cove, or some equally good location at the Shu- 
magin Islands would not only conserve this important fishery, but 
build it up to proportions exceeding any previous condition. Sucha 
station would be easy of construction and operation, and its establish- 
ment is strongly recommended. 
FISHES OF THE YUKON RIVER. 
Collections were made by the Alaska salmon commission in the head- 
waters of the Yukon, at Caribou Crossing, Yukon. Territory, Lake 
Bennett, and White Pass. Nine species of fish were found, as follows: 
The Mackinaw trout (Cristivomer namaycush), pike (Hsow luctus), 
Alaska grayling (Thymallus signifer), sucker (Catostomus), blob ( Cot- 
tus), white-fish (Coregonus, 2 species), and white-fish (Argyrosomus, 
2 species). The inconnu (Stenodus mackenziz) was not seen. This is 
the first collection of fishes made in the upper Yukon. 
INVESTIGATIONS IN MAINE. 
The fresh waters of this State have been under investigation for the 
past few years, and some of the results were recorded in the last annual
