CH. III.] MANAGEMENT OF FISH BY MR MALTBY. 39

 bestowed on it, I am enabled to give the mode 

 adopted by him in the management of his fish, 

 together with some other details connected with 

 it, which cannot, I think, fail to be generally 

 interesting. 



The pieces of water rented by him are five in 

 number, namely, La Hulpe, a lake about twenty 

 acres in extent ; Boilsfut, a lake of about seven

 of about an acre each; these last being fed by 

 small independent streams and springs, the water 

 from which finds its way into the larger one, 

 Boilsfut. In this the fish increase rapidly in 

 weight, and their quality is precisely the same 

 as that of river-fish, although it contains no 

 gravel or stones, and a considerable quantity 

 of mud is continually deposited in it; the nu-

 head of water always kept up (to supply a large 

 mill, which is at work below it the whole year 

 through), being the probable causes of their 

 doing so well there. 



All these waters are however so cold, that, 

 except in favourable seasons, the Carp rarely 

 breed in them to any extent, one year only, out
