[7] PROPAGATION OF SCHOODIC SALMON IN 1879-'80. 739 



Ripley are of opinion that more fish have run past us than we shall 

 catch this season. I don't think they are right. On the last day of 

 fishing, September 14, Forbes caught 17, and he says they did not bite 

 better at any time in spring or summer. 



The nets were put in two or three days before the 15th instant. 



Considerable progress has been made in a ditch which is intended to 

 bring more spring water into the old hatching-house from a pool on the 

 upper side of the turnpike, which appears to be filled by neighboring 

 springs. 



This afternoon I set my three men at work on the excavation for a 

 hatching-house by the stream, on the site occupied by a temporary 

 structure last year. We throw a dam of logs and stone across the 

 stream and turn the water against the bank. 



October 1, 1879. — Arrived again from Bucksport at 11 a. in., via Prince- 

 ton and Big Lake. Water high for the season in Big Lake, but has 

 lately fallen some. Has fallen slightly in Grand Lake. 



I find the excavation for the new hatching-house by the stream com- 

 pleted or nearly so. The ditch for aqueduct to old hatching-house has 

 progressed some and a very hard piece of ground reached where many 

 rocks will require blasting. 



October 9, 1879. — Having all the materials collected, we slack a cask 

 of lime and begin digging a trench to receive a concrete foundation for 

 our new hatching-house by the stream. This afternoon I find the 

 ground in our excavation to be about 22 inches below the level of the 

 mill-pond from which we must take our supply of water and eight 

 inches higher than the stream at the point at which the hatching-house 

 must discharge. The stream has perhaps been raised a little at this 

 point by our debris being driven into it just below. The ground here 

 is all clay — no bowlders except on the surface. 



Munson and Ripley to-day finished blasting in the aqueduct ditch, 

 which is now very nearly complete. The first water was struck 260 

 feet from the hatching-house, where a small vein oozed out of the east 

 bank ; several veins above that before reaching the pool. Total length 

 330 feet = 20 rods. At a rough estimate there is five feet fall from bot- 

 tom of upper end of the ditch to the eaves of the hatching-house, at 

 which height I propose to take the water into the building. Surface of 

 pool is three feet higher still. North of this pool, on a hillside, at a 

 distance of 500 feet and an elevation of nearly 25 feet above this pool, 

 is a large spring, whose waters spread over a good deal of ground and 

 then sink out of sight. I shall make my arrangements to lead this, at 

 some future time, into the aqueduct laid this fall. (This was accom- 

 plished the next season.) 1 shall lay an aqueduct of logs, using 2£- 

 inch bore below the road, and If above it. The logs are partly bored 

 already. Mr. William Cavanagh, of Saint Stephen, is doing the work. 

 We use green Norway pine sticks, 7 inches at the top for small bore 

 and 9 inches for large, 14 to 16 feet long.
