Astronomic observations were taken whenever possible to determine the 

 bearings of the lines run, and the results of these observations are recorded in 

 the field notes on the proper pages. 



The traverse of the eastern part of lake St. Joseph was started at a point 

 on the south side of the narrows on Lake St. Joseph, 59.00 chains north of the 

 sixty-first mile post on the meridian line run by myself in 1919. This is the 

 same point from which I started the traverse of the western part of Lake St. 

 Joseph surveyed in 1920, only this year the traverse was made towards the east. 



The whole of the south side of Lake St. Joseph lying east of this meridian 

 was traversed as far east as a point about six miles in a direct line east from the 

 meridian of 1919. The traverse of the north shore was also conducted westerly 

 from the east end of the lake, to a point about two miles west of where it would 

 be intersected by a northerly production of the third meridian. This leaves 

 an unfinished portion on the north shore of the lake, about ten and a half miles 

 across in a direct line. This unfinished portion includes a large bay with num- 

 erous islands, some of them quite large. It was not possible to traverse this 

 portion of the lake owing to lack of time. The prevailing rock formation in. 

 this section appears to be Laurentian and the opportunities for successful pros- 

 pecting do not appear to be so great as in other sections, so it was decided thai 

 it was more important to complete the traverse of the other portions of the lake. 



The traverse was tied to the base line wherever possible and to each of the 

 meridian lines run north from the base line. It was continued on the south 

 side of the lake as far east as the Indian Reserve south of Osnaburgh. On 

 the north side of the lake at the eastern end, the traverse was carried sufficiently 

 far to tie in the Hudson's Bay Co.'s property at Osnaburgh, and also the Indian 

 Reserve north of this point. At the east end of Lake St. Joseph the only portion 

 not traversed is the large island between the northerly and the southerly out- 

 lets of the lake, and a number of small islands adjacent to this large island and 

 to the northerly Indian Reserve. 



In the traverse all angles were measured with a transit, and the distances 

 were obtained by stadia or micrometer. The bearings of the traverse courses 

 were checked by astronomical observations at frequent intervals and also by 

 ties to the base and meridian lines. 



Every night the traverse work of the day was plotted on cross section 

 paper to a scale of twenty chains to an inch. By this means any error in the 

 traverse was at once located and corrected. The closing errors in the traverse 

 were never more than twenty-five links to the mile, and were usually much 

 less than that. 



As in the previous season, at intervals of about a mile on the shore, prom- 

 inent trees were plazed on four sides, and marked on the side next the water 

 with the letter "P," followed by the number of the tree, thus, P. No. — . Sim- 

 ilarly the islands were marked by having the letter "I" following by the number 

 of the island. In cases where no suitable tree was available, a substantial post 

 was planted in a mound of stones and marked as indicated above. These 

 trees and posts were all tied to the nearest transit station, and the bearing and 

 distance to the tree or post from the transit station recorded in the field notes. 



The details on the traverse showing all measurements, all posts and trees 

 marked as monuments, and all information necessary for the proper interpreta- 

 tion of plans, have been plotted on a scale of ten chains to an inch, and tracings 

 of these detail sheets have already been sent to your department. A plan on 

 a scale of one mile to an inch has also been prepared on mounted drawing paper. 

 This plan shows the base and meridian lines and their relations to the sur-
