A Canadian Forest Survey. 401 



and continued running a watershed line about this latter river; 

 after reaching its head it hauled across the divide into the river 

 a Mars valley, and ran a watershed line around the head of that 

 river. At its final point it was some forty-five miles from the 

 depot, about thirty-five miles of which were covered by hand- 

 sled. 



Party No. 2, a surveying and estimating crew, started at the 

 mouth of the river Moncouche, ran a stadia traverse from there 

 to the starting point of Party No. i on the Cyriac, returning to 

 the Lac des Ilets depot, shifted itself, and ran a base line twelve 

 miles southerly from a point near said depot, thereby intersecting 

 Party No. I's first line; by the line it had begun its course south, 

 certain work had already been done by Party No. 3, so that 

 Party No. 2 could also, using its line, as fast as run, as a base, 

 send out caliper crews east and west, and cover an allotted terri- 

 tory, exploring and surveying at same time. Incidentally, hauling 

 on hand-sled was the big problem of the work, where supplies 

 had to be kept in to rapidly moving crews far from their base. 

 After reaching the line of Party No. i, Party No. 2 followed up 

 the river du Moulin, resolving itself into a calipering party en- 

 tirely, covered the territory already bounded by Party No. i, fol- 

 lowed that part onto the a Mars shed, and covered that territory. 

 Party No. 2 kept in connection with the base of supplies, con- 

 tinually pushing sled loads inland toward No. i, so that No. i 

 could send men back and draw from the caches so established ; by 

 this means a good sled beat from the Lac des Ilets depot to the 

 farthest point surveyed, with hauling in separate average lengths, 

 was wide and held open. 



Party No. 3, also a combination line and estimating party, ran 

 an arbitrary base line from the Lac des Ilets eastward to the river 

 du Moulin, re-stocked at that river's depot, turned, and ran 

 southerly to a line already established by Party No. i, thus bound- 

 ing a part of the tract it was to estimate ; on the Party No. i line 

 it set itself over and ran back to the first base line, estimating at 

 the same time it made line. 



After each of these parties had completed the above mentioned 

 work they reported to the Chicoutimi office, and were turned onto 

 the final tract, a small area nearer the village. So well did all 

 plans work out that there was not a week's difference in the 

 ending of the surveys of the three parties, and by massing the
