stones arid plants upon which spawn has been 

 deposited ; and in this way fish may be brought 

 out in a warm room. With some hardy kinds, 

 as eels, bream, carp, &c. it is not necessary to 

 take the same precautions as with the smelt and 

 bleac ; but, with the greatest care, no one will 

 ever localize fish in any pond which is not pre- 

 viously amply supplied with the food on which 

 they feed. Some, as the vendace, live for the 

 most part upon one peculiar animal ; and we 

 can readily account, therefore, for their extreme 

 rarity, and also for the failures which have so 

 often accompanied the attempts to stock a pond 

 with this, as well as many other kinds. Salt 

 water fish can, of course, be preserved in ponds 

 only which communicate with the sea ; and the 

 most perfect, indeed I believe the only one of 

 the kind in Britain, is at Logan, the seat of Col. 

 M'Dowal, in Galloway. This was formed in 

 1800, and consists of an artificial basin o ' salt 

 water, thirty feet deep, by a hundred and sixty 

 in circumference. The area within, is wholly 

 hewn from the solid rock, and communicates 

 with the sea by one of those fissures or natural 

 tunnels, so common on bold and precipitous 

 coasts. It was formed by blasting the rock, and 

 a barrier was erected at its entrance, formed 

 by a pile of large loose stones, so placed that no- 

 thing but water could find egress or ingress. 

 A neat cottage, for the accommodation of the 

 fisherman, is attached to the pond, which is sur- 

 rounded by a high wall, at least three hundred
