68 U. S. BUREAU OF FISHERIES. 



GRAND LAKE STREAM (ME.) SUBSTATION. 



A valuable addition to the rearing facilities at this substation 

 was the acquisition, without cost to the bureau, through the courtesy 

 of the St. Croix Paper Co., of control of the canal formerly used 

 for the passage of boats over the quick water of Grand Lake Stream. 

 Two ponds, each approximately 100 feet long by 25 feet wide by 3 

 feet deep, were constructed in this canal and proved entirely satis- 

 factory for the purpose intended. Sliding gates at the point where 

 the canal leaves Grand Lake control the flow of water through the 

 ponds, and at slight cost additional ponds may be added to the 

 present system. 



At the beginning of the fiscal year there were on hand some 74,000 

 landlocked-salmon fingerlings, which were distributed in local waters 

 during the summer months. The fall fishing operations resulted in 

 the capture of 451 adult landlocked salmon, 192 females and 259 

 males. These fish averaged about 2^ pounds in weight, and approxi- 

 mately 252,000 eggs were obtained from them. One hundred thou- 

 sand of these were shipped to St. John, New Brunswick, on behalf 

 of the Canadian fishery authorities. The State of Maine furnished 

 the station with 25,000 eggs of the same species from its hatchery 

 at Oquossoc, and these, with the remainder from the local collec- 

 tions, produced fish for the restocking of local waters, about 100,000 

 fingerlings remaining on hand at the end of the year. During the 

 spawning season unusually low water stages prevailed in both Dobis 

 and Grand lakes. This condition was probably a factor in the 

 reduced numbei-s of eggs taken, but it hardly explains the remark- 

 ably low average weight of the spawning fish handled. 



The long-talked-of screen at the outlet of Grand Lake was com- 

 pleted during the year, the work being efficiently accomplished under 

 the auspices of the Commissioner of Inland Fisheries and Game of 

 the State of Maine. It will be of interest to note the effects of 

 this installation on the salmon fishing of the waters involved. 



In connection with the collection of landlocked sahnon, a small 

 number of brook-trout eggs was also taken, and 150,000 eyed eggs 

 of this species were obtained from the State of Pennsylvania. Five 

 thousand eggs of the local collections were delivered to a Massa- 

 chusetts applicant; all of those remaining were incubated for local 

 waters. In distributing the output the bureau is indebted to the 

 local guides and bout owners who willingly carry the fingerlings 

 to all of the important planting grounds, even the most remote, 

 without expense. 



ST. JOHNSBURY (\'T.) STATION AND SUBSTATIONS. 

 [A, II. DiNSMORi;, Superintendent.] 



Under this heading are included the main hatchery at St. Johns- 

 bury, Vt., the substations at Holden and Swanton, Vt., and York 

 Pond, N. H., and various egg-collecting points in Vermont and 

 Maine. The work of the Swanton (Vt.) substations is outlined in 

 connection with the propagation of the Great Lakes fishes on
