108 REPORT OF THE No. 3 



attached latitude and departure sheets, when balanced against the chained 

 distances on the township lines. The rod used was a sliding stadia rod with 

 a total length of thirteen feet, equipped with a fixed foot target and a sliding 

 vernier target. The rodman, in the front canoe, read the rod and noted the 

 reading. In a few cases, where it was impossible, owing to heavily wooded 

 shore line, to get stations within stadia shot, triangulations of the distances 

 were made by laying off a right angle base of fifty or one hundred feet and 

 reading the angle subtended by this base, and solving for the distance equal 

 to the base by cotangent of the angle. Observations on Polaris were taken 

 as often as possible, and the calculations of these are attached to this report. 

 In some cases, owing to the extremely low water, it was possible to get instru- 

 ment stations on sand and gravel bars in the centre of the river, and materially 

 added to the speed of the work. 



Timber. 



Notes on the timber met with during the progress of the work, will be 

 found on the accompanying plan. Much of the country, from the beginning 

 of the work to the west boundary of the Township of Cairo, has been burned 

 over, some of it for the second and third time. There are two fine areas of 

 timber along this route: one of white and red pine, along the shores of Upper 

 Matachewan Lake, and another of jack pine, around the small lakes in the 

 centre of the Township of Robertson. 



Water Powers. 



Most of the falls and rapids met with on this work, are on the Montreal 

 River in the townships of Kimberley and Cairo, and are shown on the accomp- 

 anying plan. No good site for a dam exists at the Long Rapids, that would 

 make it feasible to utilize the total drop in this section of the river. In the 

 township of Baden, the traverse was tied to the Power Reserve of Big Bend 

 Falls, which is a short distance upstream on the west branch of the Montreal 

 River from Upper Matachewan Lake. As the falls did not come within the 

 limits of the traverse, no further data was taken. 



Buildings and Improvements. 



The buildings along the river are of the usual log construction, and are, 

 in most cases, in good repair. There is one frame building at the Matachewan 

 post of the Hudson Bay Company. There are no dams along this route, the 

 only improvement in the river itself being the dock of the Matachewan Gold 

 Mines, a short distance above Fox Rapids, in the township of Cairo. 



Islands. 



All islands were given a designating letter, which was marked on a tree 

 or post set in a prominent position. A sufficient number of readings were 

 taken to give an accurate outline of the island, and if a closed traverse was, 

 at any time required, it could be figured from the position of the different 

 readings. No attempt was made to run a closed survey of each island, as in 

 many cases it would have necessitated probably half a day's chopping for the 

 entire party, on account of the amount of timber and brush overhanging the 

 shore line.
