84 REPORT OF THE No. 3 



started work. The general utility man then took the front end of a 200-foot 

 tape with one of the chainmen, while I re-ran the line and the other two chainmen 

 used a 2 chain tape. In this manner from 4 to 5 miles of trial and final lines 

 were frequently run in a day. 



Until the chainmen became proficient with the clinometer, some lines were 

 double chained twice and one or two miles thrice, but in most instances in 

 addition to my preliminary chaining, the difference between the two chains was 

 seldom more than 3^ link and frequently 2/10 link. 



Four rock posts were established during the survey as shown on accom- 

 panying notes, and the geodetic survey triangulation point Lot 6, Concession V, 

 Munro, tied in. 



Instrument Work 



Two 5-inch Cook instruments were carried on the work, the one used being 

 kept in first-class adjustment. In many cases each mile point could be sighted 

 from an intermediate point and in some instances the pickets were visible for 

 a much greater distance. 



Intersection or deflection angles were in most cases read after the line 

 between posts had been established, and in several instances were from post 

 to post. 



Posts, Pits and Mounds 



Great difficulty was experienced in finding timber sufficiently large or 

 sound enough for 6-inch posts, and many had to be carried great distances. 

 A timber scribe was used for marking posts. 



The regulation pits and mounds were constructed as per instructions and 

 wherever possible stone mounds were used, even if stones had to be carried a 

 considerable distance. 



Observations 



Due to good visibility and long sights the seven observations taken, pretty 

 well controlled the whole situation. I did not use a sidereal watch, preferring for 

 accuracy sake a very reliable standard time-piece and reduced to sidereal time 

 on the ground. 



My observation on Lots 6 and 7, Concession 4 and 5, Munro, checked to 

 the minute with one made two miles farther north in 1926. 



Geology 



The presence of serpentine, porphyry and diabase south of Painkiller Lake 

 and a diabase outcrop on Lot 11, Concessions 5 and 6, near an old shaft was 

 all of importance noted along or near the line between Concessions 5 and 6. 

 A large body of porphyry also crosses the line between the north halves of 

 Lots 3 and 4, Concession 3, Beatty, and in the opinion of the writer is the westerly 

 continuation of a very important geological condition that follows the low lying 

 land, roughly along the creek in Concessions 2 and 3, Munro to Dead Man's 

 Mountain, Lot 8, Concession 2, of the same township. Very little work has been 

 done on account of the depth of overburden, but large bodies of porphyry such
