78 EEPOKT OF THE No. 3 



Plan. 



The plan of this work has been extended beyond the actual limits of the 

 survey in order to show connections with the base and meridian lines previously 

 run. The outlines of all lakes and streams have been shown with the connecting 

 creeks and portages, and the outlines of all timber berths and mining locations 

 of which I have record have been plotted. 



Connection. 



I have been unable to reach any definite conclusion as to where this base line 

 should intersect the 7th, meridian. 



Using Niven's chainages the lengths of the east and west boundaries are :- — 



East Boundary. West Boundary. 



24 miles on 6th meridian East Boundary, Kingsf ord 6m.5c.59 



lm.37c.93 connection " " Richardson. . .6m. 6c.50 to 6th m. 



— 6th m. DOSt to 49th 6m.9c.(>0 



25m.37c.93 49th to base 7m.l8c.41 



i.e. base line lc.57 too far north 25m.39c.50 



But Niven's 1st base having a latitude of 48° 45' 30" would be at a distance 

 of 16m.55.83 south from the 49th, which would put the 34th mile post at a 

 distance of 7m.34c.l7 north of the 49th. The latitudes given on O.L.S. Niven's 

 plans do not appear to be quite correct. Latitude of Carpenter base is given 

 as 48° 44' 10", by distance south of 49th, this should be 48° 44' 08.4". 



Latitude of first base is given as 48° 45' 30" by distance lm.37c.93 north 

 of Carpenter base this should be 48° 45' 25.3". 



Latitude of 3nd base at 34th mile is 48° 50' 43", this gives a latitude for 

 the 1st base, six miles south, of 48° 45' 39". 



Latitude of my base is 49° 06' 16.7" from which a line 34 miles south would 

 have a latitude of 48° 45' 36.3". 



If the latitudes given for the Carpenter base and the 1st base are taken 

 the distance on the connection line would be lm.43c.63 in place of lm.37c.93 

 as given by Mr. Niven. All of this seems to show that the latitude of Niven's 

 1st base at the 90th mile would agree very closely with that of a line 34 miles 

 south of my base. 



There is an excess in my chainage between the 6th and 7th meridians. 

 Using Niven's chainages and following his base and meridian lines the distances 

 are : — 



South line, 6th meridian to Carpenter meridian ^^^^^-JS
