gone, are now becoming more numerous. The fact that the 

 fish stay close about the island where the water is shallow 

 makes the estabhshment of the preserve possible. 



The salmon and haUbut fisheries of the Alaskan waters 

 have long been the source of much profit. This region, 

 owing to the many bays and islands, fairly swarms with 

 fish of many kinds. Protection will soon be needed here 

 if this great storehouse of fish is to be kept filled. 



The cod fisheries of the Newfoundland banks are among 

 the most valuable in the world, and are almost the only 

 ones where fishing has long been carried on and where the 

 supply is not decreasing. The "banks" are formed by a 

 great flat reef four hundred miles long, over which the water 

 is shallow enough to offer a fine home for cod. 



Hatcheries have been established in many parts of our 

 country for the purpose of collecting and hatching fish eggs. 

 These are used for restocking those waters that have been 

 fished out. After the eggs have hatched and the young 

 fish have reached a certain stage, they are shipped to the 

 streams where they are needed. The United States fishery 

 on the McCloud River, California, has distributed rainbow 

 trout all over the United States. Shad and striped bass 

 have been brought from Eastern fisheries and planted in 

 Pacific Coast waters, where they are now rapidly increasing. 



Thus we learn that valuable food fish five within certain 

 narrow bounds instead of being distributed all through the 

 waters of the globe. It is as easy, with our many ingenious 

 devices of net and weir, to destroy the inhabitants of the 

 water as it is to destroy those of the land with guns.
