ALASKA FISHERY INTELLIGENCE SERVICE. 
Through the cooperation of the Alaska Military Telegraph & 
Cable System, information was sent to and posted at frequent in- 
tervals in the telegraph offices at Wrangell, Petersburg, Craig, Sitka, 
Juneau, Cordova, and Seward, reporting the price of fresh halibut, 
sablefish, and red rockfish at Ketchikan. At less frequent intervals 
the price of pickled salmon and herring was also reported. In like 
manner the Seattle price for the same fresh and pickled fish was 
reported to those towns and to Ketchikan. This service is under- 
stood to have been of real value to the fishermen in enabling them to 
take advantage of the best market for their products, and it was con- 
tinued for their benefit. 
INSPECTION OF CANNERIES. 
Canneries in Alaska are subject at all times to inspection by em- 
ployees of the Alaska service of the bureau, but this inspection is 
limited chiefly to an examination of the fish with reference to the 
time they have been dead. The inspection also includes the wanton 
waste of food fish in Alaska, whether at the fishery establishments or 
on the fishing grounds. 
There is also a cannery inspection service authorized by the Na- 
tional Canners’ Association but supported largely if not entirely by 
the packing companies operating canneries in Alaska or by as many 
of them as contribute to the maintenance of the service. The plants 
of companies which do not contribute are not inspected by employees 
of that service. This work is somewhat in its infancy, having been 
started rather experimentally two years ago chiefly, it is understood, 
to reduce the fire risk at the canneries, to further provide for satis- 
factory sanitation at the plants, and to promote the general -welfare 
and comfort of employees. The work of this service is no deubt well 
worth while, although it has no mandatory authority to prevent the
