An Anglers Paradise. 31 
or of Jacobi, having probably never heard of either of them, nor 
even read a book on Natural History in their lives. Nothing was 
heard of the discovery beyond the department of the Vosges, 
before the year 1849, when Dr. Haxo, of Epinal, secretary to the 
Société d’ Emulation, and member of the Conseil Académique of 
the Department of the Vosges, sent a communication to the 
Academy of Sciences at Paris, describing the method of cultivating 
fish, as practised by Gehin and Remy. The effect of this paper 
was great, and it sorely puzzled many who heard it, that it should 
have fallen to the lot of two poor fishermen to put into practice 
and shew the value of a discovery which had been known to many 
learned men for a long series of years. 
The subject was at once warmly taken up by the Academy, 
who, seeing the great importance of the discovery, lost no time in 
calling the attention of Government to it. The Government 
decided to carry on the process on many of the rivers of France, 
and Gehin and Remy were sent for and employed at good 
salaries ; and a Commission, consisting of a number of scientific 
men, was also appointed to superintend their operations. The 
plan adopted by these two men for the artificial cultivation of 
trout, was to procure a number of round boxes made of zinc, in 
shape somewhat like a cheese, and about eight inches in 
diameter. These were riddled with small holes, and in each of 
the boxes was placed a layer of fine gravel, and upon this the 
eggs were laid. The boxes were then placed in the bed of a 
stream and covered with loose pebbles, and the water was allowed 
to percolate through them by means of the small holes. The 
young fish on being hatched were kept in these receptacles from 
eight to fifteen days, and then set at liberty. 
Although it was long considered that the gravelly bed of a 
natural stream was a requisite in fish hatching, which could not be 
substituted, an eminent French naturalist, M. Coste, Professor of 
the College de France, at Paris, discovered that it might to a 
certain extent be done without, and he proved his assertion by 
producing salmon in a tub. Having procured a large tub, he had 
a number of small conduits or canals constructed in it, and 
placed in such a position that the water flowed from one to the 
other, and at last, when its services were no longer required,
