81 



Of older fishes of various kinds brought over, tliere svere 433, in addi- 

 tion to 199 adult sea salmon purchased jointly with the Maine commis- 

 sioners from the Penobscot River catch, the latter having been confined 

 in the inclosure at Dead Brook to await maturing of their eggs in 

 November of this fiscal year, when they were manii)ulated and returned 

 to open waters. Besides 270,500 fish in process of rearing, shown in a 

 preceding table, there were on hand at the end of the year 242 wild 

 Atlantic salmon, purchased in June as prosi)ective spawners, and also 

 those species enumerated in the subjoined statement: 



Meteorological data of the year is presented in condensed form below. 

 The water used at the liatching-house flows through a conduit having 

 connection with the brook at a point above the sources of the springs. 

 Pond B, referred to in table, being situated below the hatchery, receives 

 a mixture of brook and spring water. It is a small pond, which, till 

 May, 1893, accommodated the Atlantic salmon previously referred to 

 as having been acclimated. The north stand of rearing-troughs, out- 

 door situation, is fed from above the hatchery, receiving commingled 

 waters of brook and springs. Alamoosook Lake, a body of fresh water 

 about 5 miles long, on the bank of which the station is located, became 

 closed by ice formation December 12, and was not again open until May 

 1. On February 10 the ice measured 28^ inches, and was crossed by 

 teams December 25 and April 8. Early in December exposed water 

 conduits were protected by a covering of hay, boards, and evergreen 

 brush, and toward the end of the month the two ice-houses were filled 

 from the lake. The observations on which the table is based were 

 made daily, at 7 a. m. and 2 p. m., omissions in June being incident to 

 shutting off water for repairs :
