all form admirable food for Salmonidae, and can be easily 

 cultivated in any small clear stream. 



The food of the carp consists chiefly of the larvae of water 

 insects, worms, sprouts of water plants, and decaying vege- 

 table matter. Kitchen refuse forms very fattening food for 

 carp. To rear carp with the greatest success the parent 

 fish should be placed in a suitable pond in which there are 

 no other fish ; they spawn in May and June ; the parent 

 fish should then be netted out, and in the autumn, under 

 suitable conditions, there will be an immense crop of young 

 carp from two to three inches in length. The carp is a 

 powerful fish affording great sport to the angler, and its 

 cultivation might be most profitably carried on in England. 

 In fact before the advent of Protestantism in England fish 

 stews for the natural propagation of carp and other fish 

 were very common. 



The Roach, Rudd, and Bream spawn in May or early. in 

 June on water weeds ; the eggs hatch out in a week or ten 

 days. 



The Chub spawns at the end of April or beginning of 

 May, on shallow sandy or gravelly places, and the eggs 

 hatch out in a very short time. 



The Barbel spawns on stones and gravel, in a sharp 

 stream from one to three or more feet deep ; how long 

 the eggs take to hatch out I have not been able to ascer- 

 tain, but probably in a week or ten days. 



The Dace spawns in March or the beginning of April, 

 also in sharp shallow streams. There are some valuable 

 foreign coarse fish which I think might be advantageously 

 introduced into this country ; but as my friend Mr. Oldham 

 Chambers is to give us a Paper on the acclimatisation of 

 foreign fishes, I will only refer to one of these, viz. the 

 American black bass, because this fish thanks chiefly to
