[7") PROPAGATION OF SCHOODIC SALMON IN 18Sl-'82. 1097 



November 13. — First suow of the season last night — a mere trace. 

 The temperature of the lake has fallen since November 4 from 49 to 41. 

 Spawning still continues. No large runs of salmon ; on night of 11th and 

 12th only 25 in all. Yesterday we began to put eggs into the stream 

 house, hatchery No. 2. 



Novemher 14. — Two nights have brought in b#t 50 salmon. It appears 

 that the season is drawing to a close. 



Novemher 19. — The last day of spawning. We had but 27 gravid 

 females on hand this morning. Twenty of them yielded spawn, and 

 they, with the 7 remaining unripe, were placed in the final inclosure, 

 whence they are to be taken up the lake and liberated. The work of 

 transportation begins to-day. 



November 21. — The transportation of fish concluded to-day, and part 

 of the iuclosures taken from the water. The main nets are left in place 

 for some days, to prevent the fish that have been turned loose descend- 

 ing the canal and stream, which many of them (perhaps 20 per cent.) 

 attempt to do immediately after they are set free, notwithstanding they 

 are freed one or two miles up the lake. Two inches of snow on the 

 night of 19th. All the eggs deposited in hatchery No. 1 are transferred 

 to No. 3, the latter, Avith No. 2, having ample accommodations for them. 



November 22. — Eeturned to Bucksport, leaving everything in charge 

 of Mr. Munson. 



January 11, 1882. — ^Arrived from Bucksport at 8.20 p. m. 



January 12. — To-day I find at hatchery No. 3 that the west aqueduct 

 is delivering 20 gallons of water per minute, and the south aqueduct 10 

 gallons. Munson says the volume has been about the same all the winter, 

 except immediately after hea\y rains, when it was greater. Wfe have 

 now 485,000 eggs in the new hatchery, and 200,000 additional will be 

 immediately brought up from the river house to hasten their develop- 

 ment, so that they may be ready for shipment before March. Munson 

 thinks the rate of impregnation is better than usual this year. We 

 took a tray of lot 1 (earliest eggs), picked out 110 contiguous eggs, and 

 found only 5 of them unimpregnated. 



January 13. — Transferred 200,000 eggs from No. 2 to No. 3. These 

 have been in very cold water, averaging a little less than 34^ since they 

 were put in the troughs in November, and their eyes are not yet formed. 



January 17. — This p. m. Munson picked the unfertilized from six 

 stacks of eggs (120,000 nearly) in two hours forty-seven minutes. He took 

 out 6,700 white eggs, being at the rate of40|^ eggs per minute, no allowance 

 being made for moving stacks back and forth, shifting trays, &c. Such 

 speedy work can only be accomplished by a practiced hand. The un- 

 fertilized have been induced to turn white by previous agitation. To 

 attempt to remove them while retaining their natural color would be 

 tedious and uncertain. 



January 18. — To-day we began shipment of spawn, sending 60,000 to 

 E. A. Brackett, Winchester, Mass., and 50,000 to H. J. Fenton, Windsor,
