34 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
NasHua STATION, NEw HAMPSHIRE (W. F. HUBBARD, SUPERINTENDENT). 
The superintendent visited Greenough and Diamond ponds and 
Connecticut lakes, in the northern part of New Hampshire, for the 
purpose of securing a site for the collection of brook-trout eggs, and 
selected Diamond Pond as the most favorable place, and during the 
latter part of September two of the employees of the station were 
detailed to that point. A rough shanty was erected and the necessary 
troughs provided. The fishing was done with hook and line and with 
gill nets, and continued until November 30. During this time 909 trout 
were captured, of which 357 females produced eggs. The first were 
collected on October 12 and the last on November 30, the number being 
estimated at 140,000. At the close of operations the men returned to 
the station, leaving the eggs in charge of a watchman until the last of 
January, when it was found that they numbered only 15,120. The loss 
was attributed to the carelessness and ignorance of the watchman. 
From the brood fish at the station 100,000 eggs were collected 
between October 13 and December 20. In January 500,000 brook-trout 
eggs were purchased from dealers in Massachusetts, and an assignment 
of 50,000 was received from the New Hampshire commission, also some 
landlocked-salmon and golden-trout eggs, which will be hatched and 
planted under their direction. 
A fair percentage of all the eggs received hatched, but the fry from- 
those purchased and from those belonging to the New Hampshire com- 
mission suffered very heavy losses when about 4 or 5 weeks old. As 
fry from eggs taken at the station and from Diamond Pond were not 
similarly affected it is believed that the eggs were of poor quality. 
During the spring 191,000 fry were planted in local waters, and 
there remained on hand at the end of the year the following stock:

In the early summer the employees at the station were occupied in 
making a number of improvements in the superintendent’s cottage, 
and, assisted by a crew of temporary men, a number of new nursery 
ponds, 14 feet long by 8 feet wide, were constructed, and a storm ditch 
3 feet wide and 2 feet deep was built for the purpose of protecting 
the ponds from freshets caused by surface water during the wet sea- 
son. Since its construction it has several times prevented the ponds 
and hatchery from being flooded, which would have caused the loss
