begun and ably conductud by Prof. Forbes, for the U. 

 S. P ish Commission ; but for some inscrutable reason 

 it was dropped. There is urgent demand for its re- 

 sumption all along- the line, by every Commission en- 

 gaged in the propagation of white fish. A source of 

 great material wealth is on the toboggan ; and if we 

 fail to employ every available means of checking its 

 rapid descent, we fail in our duty as agents and trustees 

 of a vast public estate, with its still vaster possibilities. 

 . We should be keenly alive to the fact that the mere 

 production of fry, though in vast numbers represented 

 by 8 and 9 figures, or even 8 times 9 figures, in and 

 of itself has no concrete value. We should arouse to 

 the fact that the value of fish culture as a public enter- 

 prise, or considered from an economic standpoint, is 

 ■not measured by the number of fish hatched, but by 

 the number matured ; and this paper will have accom- 

 plished all that was intended if it emphasizes the fact 

 that hatching without intelligent discrimination in plant- 

 ing, is a ship at sea without a rudder, an arch without 

 a key-stone.
