FISH-BREEDING. 467 



naturalist communicated the result of his experiments to 

 Count ae Goldstein, Grand Chancellor of His Palatinate High- 

 ness for the Duchies of Burges and Juliers, in an essay in 

 the German language, which Count de Goldstein afterwards 

 translated into Latin for M. de Fourcray. It appears strange 

 that so important a discovery should not have been made 

 public, and followed up at the time by establishing fish- 

 breeding as a trade or science. 



It is natural to suppose that Gehin and Bemy's discovery 

 would soon become generally known to those who were inte- 

 rested in restocking impoverished and exhausted waters. So 

 we find Messrs. Young, Shaw, and other British naturalists 

 not only in possession of this knowledge, but successfully 

 experimenting on it. 



The following extracts and wood-cuts from Mr. Fry's work, 

 I am satisfied will convince any intelligent reader that thou- 

 sands of fish may be produced and raised with as little or 

 perhaps less difficulty than a tenth of the same number of 

 poultry. I would, however, advise those who wish to engage 

 in the experiment, to procure Mr. Fry's work, in which he 

 has translated from the French, " Facts furnished the Academy 

 of Sciences at Paris, by M. Gehin ;" " M. Coste's Practical 

 Instructions in Fish-raising ;" and " M. Milne Edwards' Bepori 

 on Artificial Fish-culture, and stocking barren or impover- 

 ished rivers with fish artificially hatched." His book also 

 embraces " Lessons on the Natural History and Habits of the 

 Salmon," by " Ephemera," the gist of which will be found in 

 the previous part of this book, beginning at page 214. 



The Trout being ods of the most interesting and easily 

 procured fish, I will first refer to the method of breeding it. 

 This fish generally spawns from the latter part of September 

 to the first or middle of November. The preparatory step is 

 to procure hatching-troughs.
