68 REPORT OF THE No. 3 



missing or in poor shape. Altogether 5 iron posts were lost. New iron posts 

 were supplied. 



A new wooden post was planted at every mile, immediately north of and 

 touching the stone or iron post for the whole 89 miles, and carved with the same 

 markings as the other one, according to the old wooden post or iron post. 



During the course of the survey, points were marked permanently by us 

 by a bronze rock post and stone cairn or a rock cross with a stone cairn, or with 

 a cement post with a bronze rock post in centre of its top. Where cement 

 in bags could be got in to the line conveniently a cement post from 3' to 5' 

 long, 7" by 8" square and reinforced with iron rods, was made in a form, carved 

 with exact mile and chainage before it became too hard and then planted 

 firmly at a salient point on the line. All these permanent marks were placed 

 exactly on line between the two adjacent monuments. 



Cut stone monuments were procured at La Reine and 4 of these planted 

 at prominent points, two in Lake Abitibi, one on its north shore and one at 

 Mile 90. These were all set in a concrete base. 



Instructions were received to get stone posts for the beginning of the 

 line at Lake Temiskaming to replace those that were lost. These were ordered 

 from a monument maker, but owing to circumstances entirely beyond our 

 control were not available while we were on the ground to place them. An 

 iron post in cement at the beginning and a cement post at Mile 1 were sub- 

 stituted. 



Bearing trees if found were recorded and if good were retained. Wherever 

 available, new ones were made. The old B. T.'s had all disappeared up to 

 Mile 23. 



In the report of Patten and Laberge, stone cairns are mentioned. None 

 of these were found. 



The notes of O'Hanly and O'Dwyer in 1874 show two cut stones planted 

 at 24.85 and 24.95 chains north of the 42 miles post, one at the Height of Land 

 and the other 10 links north of it. These two posts are shown in Patten and 

 Laberge's notes at chainages 24.93 and 25.03 chains north of 42 mile post. 

 We found these two posts lying uprooted along side of the line and road. 

 There now is a good wagon road traversing this part of the line from Cheminis 

 to Labyrinth Lake. Evidently these two posts had been removed as obstacles. 

 We again planted them directly on line at chainages as shown by Patten and 

 Laberge and with their tops slightly below the surface of the ground. 



Magnetic Observations 



Observations to determine magnetic declination were made in sets of 5, 

 quite frequently, with both transits. The declination in this area is generally 

 about 12" west of north. A slight variation from the normal was observed 

 a few miles south of Lake Abitibi. This latter fact agrees closely with what is 

 found at other points in this area south of the lake according to the Provincial 

 Geologist of Ontario. 



A list of these observations is appended.
