Brook. The o<xos coiiiiiKMK'cd to lintoli tlie beiiimiiiiii- of tlie folldwing 

 April and concliulod Ai)ril L'l*. Tlie clevelopineiit and liatcLing of the 

 eggs were carried on at the new hatchery under considerable incon- 

 venience, owing to the lack of its iiennanent interior fittings, as also 

 to the presence in the water sn])[>]y of line clay sediment from the new 

 reservoir ponds. All were safely carried thr<mgh the winter, however, 

 and hatched without unusual loss. 



In January, 1802, 50,000 eggs each of the Loch Leven and Von liehr 

 trouts were received from the Northville Station in good condition and 

 placed in troughs. These finished hatching on April 7. On the 28th 

 of May an unusual mortality occurred among them. The loss had been 

 large for two weeks, and was first supposed to be due to the fact that 

 the fry (of the A^on Behr trout) were weak and puny. The landlocked 

 salmon, however, which were an unusually fine and vigorous lot and 

 ate well, suffered in like manner, and the cause was therefore ascribed 

 to the high temperature of the water — 08° and 69° F. — and also to its 

 I)assage through a closed flume which prevented its sufficient aeration. 

 The fish on hand at the close of the year were estimated to be — land- 

 locked salmon, 00,000 j Loch Leven trout, 1 6,000 j Von Behr trout, 10,000; 

 landlocked salmon hatched April, 1891, 3,800.

Preparation for the season's work was begun October 5, 1891, in the 

 commencement of the repairs and overhauling of the machiiiiery and 

 other equipment of the ^station. Active fish-cultural work was started 

 December 1, on which date 876,600 cod eggs and 1,619,400 polloekeggs 

 were secured. The taking of cod spawn continued till March 30, and 

 of pollock till ])ecember 21. The total number of eggs in good condi- 

 tion received at the staticm during the season was about 57,075,000, of 

 which 51,600,000 were cod and 5,475,200 pollock. Of the cod eggs, over 

 46,000,000 were taken in Ii)swich Bay, landed at Kittery Point, Me., and 

 thence transferred in sealed jars by rail to the station; the balance of 

 the cod eggs, as also those of the pollock, were obtained ofJ" Gloucester. 

 The following tables exhibit the details of the season's propagation 

 and distribution :
