FISH-CULTURE.

Mr. Horn's pond, on account of the severity of last winter not 

 one was visible. 



On the 22d April I returned the second lot of S.^levenensis 

 fry, 3737 in all, from rearing-box 2, a few being added from rearing- 

 box 1. They were placed in the Gairney, and carried in a new 

 tank, which did its work well, with about 10 gallons of water, 

 which was not changed on the journey. The fry were five hours 

 in the tank, and there was not a single death. Figs. 123, 124 are 

 drawings of the tank.

On the 12th May I returned the last lot of S. levenensis fry 

 to Loch Leven, 1200 in all. They were hatched on the 23d 

 January, and were put into the Gairney, about three miles above 

 the loch. The first year's stocking of Loch Leven thus amounted 

 to only 5937 fry. In the pamphlet on Stocking, I stated the 

 number at 9000, but I was wrong ; the mistake probably arose 

 from between 3000 and 4000 eggs having been left with Mr. Burns 

 Begg at Kinross on the 5th November 1874, while the total 

 number spawned (12,000) was entered on my notes.
