per minute. There is another spring on the Government property 

 between the hatchery and Eocky Pond which should be excavated and 

 put in condition. The temperature of this is 46^°, and by mingling it 

 with the water from the flume it would undoubtedly suffice for rearing 

 a large quantity of brook trout. 



Following is the list of fish and fry on hand June 30, 1895: 



Craig Brook Station (Charles G. Atkins, Superintendent). 

 The fiscal year opened with the following stock on hand : 



Atlantic salmon. — Of 174 Atlantic salmon collected at Penobscot Sta- 

 tion in May and June, 1894, 143 remained alive in the inclosure at 

 Dead Brook on July 1, but by October the number had been reduced 

 to 71, 38 of which were females. These salmon were i)urchased con- 

 jointly with the State of Maine, and of the 415,350 good eggs obtained 

 from them the United States Commission received 226,350 as its share, 

 and the State 189,000. Twenty thousand of those belonging to the 

 United States Commission were shipped to the l^ew York Commission 

 at Cold Spring Harbor, and the balance were retained at the station 

 for hatching and rearing. The eggs commenced to liatch in March and 

 finished in April, yielding 205,994 fry, of which 176,954 survived at the 

 close of the fiscal year. 



The 11 salmon hatched in 1888, and confined in small ponds over six 

 years, died during the summer. These were the parents of the three 

 broods of domesticated salmon which were hatched in the years 1892, 

 1893, and 1894, respectively. There were 2,15y of them in all at the 

 beginning of the year, but the number was greatly reduced by two 

 attacks of disease, one occurring in the summer of 1894 and the other 

 in May, 1895. The survivors (991) appear to be healthy and vigorous 

 and will be sufficient for the purpose of artificial landlocking. None 

 of them are old enough as yet to yield eggs.
