212 SEASON 1875-76. 



represents a loss of only 6'66 per cent., and a hatch of 93'34 per 

 cent, of the eggs laid down. 



The S. fario did not fare so well, principally for want of 

 space. Out of 13,800 ova laid down, I only had 2315 year-old 

 trout to show. The single lot of Queichy's eggs (milted by a 

 burn -trout) gave 1000 year-olds out of 1540 eggs. 



The following notes as to the growth of S. levenensis yearlings 

 occur, March 1876 : " Loch Leven yearling died of indigestion : 

 length, 4'13 inches ; weight, 42 ounces. Hatched January 23d, 

 1875." And March 31st (1876): " Loch Leven yearling died from 

 over-eating: length, 4'71 inches; weight, 74 ounces." 



On June 24th 1876 I began stocking the new 60-feet pond 

 at Howietoun. I placed 180 Loch Leven yearlings into it, and on 

 the 13th July I put in 343 more. That evening I went up to 

 London. There was still a little water running into the pond at 

 Craigend. On the 15th I received a telegram, that nearly all the 

 trout in the pond in front of Craigend House were dead. I came 

 north by the limited mail, and arrived at Craigend at 9 A.M. The 

 temperature of the water in the pond was 72 F. I picked out 

 630 S. levenensis trout, weighing 20 Ibs., or twenty-one to the 

 pound nearly ; but as they had lain some time in the sun before 

 weighing, it is probable that had they been weighed at once on 

 being taken from the water, they would have run eighteen to the 

 pound, or better. I netted out 555 alive, and transferred them to 

 the 60-feet pond at Howietoun. I then returned to London, and 

 next morning received a telegram to say that no more were dead, 

 and that 335 more had been safely transferred to the 60-feet 

 pond. The pond was emptied in my absence, and there was 

 ascertained to be only 1210 fish. This left me with 3060 

 S. levenensis yearlings, many of whom have since exceeded 8 Ibs. 

 in weight. On the 27th July I called at 37 Albany Street, and 

 saw Mr. Buckland. He suggested the thundery state of the 

 atmosphere ; and I think he was right, as, if it had been over- 

 crowding, my experience is that the loss would have been almost 

 total. The cause of loss is not very material, as, with the water 

 at 72 at nine in the morning, the fish must have succumbed
