the ova therefrom pkiced iu the hatching-boxes. The temperature of 

 the moss iu the box was 44"^ aud of the water in the hatching-boxes 54°. 

 Of the four trays taken out the eggs in the first two were a good deal 

 caked together, although apparently not dead. The others looked to be 

 iu good condition. As soon as the eggs were placed in water hatching 

 commenced, and the next morning a large number were hatched, but a 

 very large proi)ortion of the eggs were found to be bad and had turned 

 color. The temperature in the hatching-boxes had increased to G0°, and 

 a few days afterward was as high as 66°. 



Great difficulty was experienced in keeping the fry in the boxes, 

 although fine screens were used for the purpose. But as the water from 

 the boxes discharged into the society's ponds, the fish were not lost. 



Immediately after the four trays were taken out the remaining fifteen 

 trays were repacked with ice and sent by rail 24 miles, then by express 

 van 30 miles, to an inland lake, called Eotoiti, and a place prepared in a 

 creek, which runs into the lake, to receive the ova. 



Of the fifteen trays of ova placed in this creek a very large propor- 

 tion hatched, estimated by the man in charge at two-thirds. The tem- 

 perature was not taken, as both thermometers sent up were broken, but 

 the water is much colder than in the society's boxes, and may be stated 

 at about 48© or 50°. 



The same difficulty was experienced of keeping the young fry in the 

 hatching place, although screens were used as in the boxes; and most 

 of them got out into the lake a few days after hatching. I am there- 

 fore unable to report on the growth and progress of the fry, except 

 that those in the pond are growing and appear to be thriving. They 

 have been frequently fed with blood. 



Had the society received notice of the ova coming, more complete 

 arrangements would have been made for hatching, aud the results 

 would have been better ascertained. 



In conclusion, I have the honor to ask you to be kind enough to cause 

 a copy of this report to be forwarded to Professor Baird, of the U. S. 

 Fish Commission, with the thanks of this society, as previously conveyed 

 to you in my letter of the 21st ultimo.

The cod gill-net fishing is most over, the fleet being reduced from 52 

 to 8 sail. Those remaining did well last week. The boats that used 

 nets are now fitting out for spring fishing, and, had there been more 

 nets, would have used them longer.
