The distribution of this enormous output required 641,250 

 miles of travel, 123,394 miles of which were performed by the 

 special cars of the Fisheries Bureau, and the remainder by 

 detached messengers. All transportation was paid for with 

 the exception of 12,314 miles of car service, and 81,355 miles 

 made by messengers. 



In order to obtain these enormous annual supplies of young 

 fish and fish-eggs, covering forty-five species of food fishes, 

 the Government maintains thirty-four permanent fish-hatch- 

 eries, open and operated all the year round, and one hundred 

 and two subhatcheries, auxiliaries and egg-collecting stations. 

 These are scattered through thirty different states and 

 Alaska. This industry may be regarded as a great ever- 

 working machine, in constant operation to put back seed- 

 stock in the place of what the commercial and other fishermen 

 annually take out of our waters. In addition to this many 

 states have state hatcheries. The one recently finished by 

 the state of Kansas, at Pratt, under the direction of Professor 

 L. L. Dyche, is said to be the most extensive and mechanic- 

 ally perfect single hatchery thus far developed in America. 



The thirty-four permanent hatcheries of the National 

 Government may be classified as follows:
