COLLECTION AND DISTRIBUTION OF SCHOODIC SALMON EGGS. 791 



seasons, and both the lake and the springs were at a low stage. A 

 careful measurement of the amount flowing through the troughs at 

 the old hatching-house indicated" but a trifle over four gallons per min- 

 ute on the 23d of August, 4.164 gallons per minute on the 28th of Sep- 

 tember ; on the 9th of November, after the leaks were stopped, this had 

 risen to 8.4-7 gallons per minute ; on the IGth of November, to 12.86 gal- 

 lons per minute. 



2. — Fishing and spawning. 



The progress of the season's work is sufficiently portrayed by the fol- 

 lowing extracts from my note book, and interpolations. 



August 23, 1878. — All reports agree in representing the fishing last 

 spring and early summer to have been uncommonly fine. Fish were 

 plenty, and of itu wonted size and fatness. At the dam all the gates 

 are now open, and a lot of logs fill the large pools below our works 

 and partially obstructs its outlet. Consequently the water at our catch- 

 ing and spawning ground is unwontedly high (not high in lake, how- 

 ever). At the dam, in the n^jper end of the sluice- gate- way, that is, on 

 the upper edge of the rollway, the water is 10 inches deep. At our 

 gauge, on the pier above the dam, the water stands at 2 feet 2 inches 

 exactly, mth calm air and still water. 



September 28. — Arrived yesterday from Bucksport (second visit). The 

 nets were put across the stream and the head of the tannery canal about 

 the middle of this month. 



September 29. — The water being very clear and air still, I looked care- 

 fully all along the lower side of the dam, but not a single Schoodic sal- 

 mon was in sight. I went up to the pier where the water gauge is, but 

 saw nothing there. I think that evidently the fish are coming in slower 

 than last year. On October 6, 1877, 1 found them very plenty below the 

 dam, but then several hundred had been put in from the canal by Mr. 

 Munson. The water is some lower than last year (nearly 3 inches lower 

 than October 8, 1877), and only one gate is now open instead of three at 

 that time. Water has fallen nearly 5 inches since August 23. 



Verified the elevation of the water gauge on the pier above the dam, 

 and found it to agree exactly with the position laid down in Mr. Buck's 

 notes last fall ; that is, the 4-feet mark is on a level with the lower side 

 of a drill hole on the south face of a large bowlder, lying in the water 

 near the east shore, " about 225 feet above the dam." 



October 1. — Again carefully looked about the dam, but saw no Schoodic 

 salmon. Have not seen one since I came here. 



October 31. — Fish have begun to descend below the dam, and nightly 

 come down to our net. Munson thinks them very plenty in lake, from 

 what he has seen above the dam and been told by boatmen. He saw 

 some work in the gravel by fish at the head'bf our ma n lead on the 28th, 

 but not much done yet. 



November 1. — I see three nests begun at head of our main lead, but
