FISH-BREBDINS. 481 



Some rivers which Salmon were known never to enter have 

 been rendered productive. The manner of effecting this has 

 been to transport the parent fish when about to spawn, and 

 allow them to spawn in the stream ; or proceed according to 

 the usual mode of artificial propagation ; or to bring the 

 fecundated roe, and place it in the waters intended to be 

 stocked. It has become a matter not of mere experiment, 

 but certain success ; as much so as a farmer getting his wheat 

 or potatoes from another part of the country, in view of 

 increasing the product and quality of the crop by a change 

 of seed. 



I should not wonder if fishing clubs in England have 

 resorted to this means of restocking their exhausted waters, 

 and now find good angling in streams that previously afforded 

 but a limited amount of sport. 



I have before adverted to the fact that impregnated spawn 

 is an article of commerce in China, and that in some parts of 

 Germany, Carp-ponds drawn off for the purpose of cultiva- 

 ting the soil are not restocked when the water is let on again, 

 the fecundated ova remaining in the soil two or three years, 

 replenishing the pond. 



M. Coste advises that, for transportation, the impregnated 

 eggs be packed in wet sand, alternate layers of each ; and 

 thinks the gravel used in M. Gehin's directions would crush 

 a portion of the eggs if the box should be jostled. 



A singular evidence of the number of Trout that will 

 thrive in a small space can be witnessed at Hellertown, a few 

 miles south of Bethlehem, Pennsylvania. Owen Desh, who 

 keeps a hotel there, has a trough in his yard which is twenty- 

 four feet long by two feet wide, with a depth of water not 

 over eighteen inches. In this limited space he generally has 

 from six to eight hundred Trout, from nine to twelve inches 

 long. He has even kept twelve hundred in the same trough,
