the increase belongs to the entire community, not to 

 any individual. This may be a communistic possession 

 of property but even that is better than no property at 

 all. It is an easy and simple branch of fish culture and 

 were it assisted by proper laws and the breeding fish al- 

 lowed to reach their spawning grounds in sufficient num- 

 bers its results would be astonishing. As it is, the more 

 fish that are bred the more fishing is done and the closer 

 is drawn the barrier that shuts them out from the upper 

 waters of the rivers that they inhabit. At least forty- 

 eight hours in every week should be a close time during 

 which no fishing should be allowed in order that a fair 

 proportion at least should be permitted to fulfil the du- 

 ties and necessities of their continued existence. No 

 skill in fish culture can hatch fish when there are no 

 parents from whom to obtain the eggs. That proposi- 

 tion is self evident. 



MIGRATORY FISH CONFINED TO FRESH WATER. An 

 experiment was made by Mr. Wilmot of Canada, by 

 which it is thought to be proved that salmon can live in 

 fresh water wholly, if they are permitted to migrate for- 

 ward and back from the great lakes into their fluvial 

 tributaries. This change, it is claimed, satisfies the 

 demands of their natures and supplies them with abun- 

 dant and fitting food. A similar conclusion appears to 

 be reached in reference to the shad. A number of the 

 fry were deposited in the Genesee river, and were seen in 

 that and Lake Ontario, where they appeared to remain till 

 they were grown. They increased in size year by year 

 and were caught frequently in nets near the mouth of the 

 Genesee. Some were large enough to be marketed, and 

 it is possible that they bred of themselves, as their num- 

 bers instead of diminishing, augmented. In four years 

 after they were introduced, they were observed in im-
