 fecundity. Amongst those who have adopted this means,

 connected with a biscuit bakery.. It is in contemplation,

 produce of the Severn, and to stock some of the other 

 rivers of England with salmon. Even the polluted Thames 

 is included in the number ; side drains for the filth dis- 

 charged into it by London, having been talked of. The 

 Thames Angling Preservation Society have a hatching 

 establishment, and have introduced the grayling. In the 

 season of 1863-4 they turned out about 40,000 young

 sea through the impure water of the Thames opposite London, and 

 gives' an unfavorable report generally, of the results of this enter- 

 prise thus far.
