gathering herring and whitefish eggs at Erie, Pa. These eggs 

 turned out a very large percentage of fish. 



A large amount of repairing has been done. The old stone 

 walls in most of the ponds were taken down below the water line 

 and replaced by solid concrete. The raceway feeding the ponds 

 was treated in the same way. Both these improvements had be- 

 come necessary to successful work at the station. We also filled 

 and graded an old ice pond below the hatchery. This greatly 

 improved the appearance of the grounds. There is some more 

 concreting to be done; but the co.ld weather prevented the work 

 this year. The pond at the head of the creek where the old 

 planks are should have concrete retaining walls, as the planks 

 are rotten. The pond itself should be dredged on account of the 

 bad condition which prevails.

Caledonia, N. Y., November 1, 1911. 



Chautauqua Station. 



As the records will show, the season from October 1, 1910, to 

 October 1, 1911, has been an active and a productive one for this 

 station. A record of fish eggs received and collected, fish hatched 

 and distributed is given in another report, which shows a decided 

 increase over any past season's work. 



Eyed brook trout eggs were bought and shipped here from 

 Charles A. Welters, Weissport, Pa. A small, unaccountable loss 

 of these eggs occurred after they were placed on the hatching 

 trays. These eggs were replaced by Mr. Wolters without charge. 

 Trouble with excessive air in the artesian water was again ex- 

 perienced with the brook trout at the fry and first stages of the 

 feeding period. Serious loss was prevented by disposing of a 

 portion of the fish at the fry period and filling the rearing ponds 

 to their capacity. As nice fingerlings were raised from these 

 fry as I ever handled. 



The Lake Erie herring work commenced at Dunkirk Decem- 

 ber 6th, closing December 19th. Spawn takers went out on the tugs
