Base and Meridian Lines and Islands in the East End of St. Joseph 

 Lake, District of Thunder Bay. 



Thessalon, Ont., March 29th, 1922. 



Sir, — In accordance with your instructions dated April 15th, 1921, I have 

 made a survey of certain base and meridian lines in the Districts of Patricia 

 and Thunder Bay, and have made a traverse of the eastern part of the Lake 

 St. Joseph and beg to submit the following report: — 



The base line was started from the 66th mile post on the meridian line run 

 by myself in 1919, was run east astronomically on a series of six-mile chords 

 of a parallel of latitudes for a distance of twenty-eight miles and twenty-nine 

 chains. At this point it was intersected by a production of the westerly 

 boundary of the Indian Reserve on the south side of Lake St. Joseph, near 

 the Hudson's Bay Company's post at Osnaburgh. The west boundary of this 

 Indian Reserve was produced south a distance of seventy-three chains, sixty- 

 four links. 



From the end of each six-mile chord, a meridian line was run north astron- 

 omically to the shore of Lake St. Joseph. 



The base and meridian lines were well cut out and blazed. A substantial 

 wooden post of the best timber available was placed at the end of "EUch i/Tile, 

 excepting where this point occurred in a lake or stream, and was surrounded 

 wherever possible by a substantial mound of stones. Bearing trees were marked 

 with the letters "B. T." after being blazed in a prominent manner, at every 

 post where possible and the distances and bearings of these trees from the 

 various posts, were recorded in the field notes. 



The number of the mile was marked with a scribing iron on the side of the 

 post facing the point from which the line was started. When the end of a mile 

 came in a lake or stream, the post was planted on the nearest shore, and the 

 chainage from the nearest mile was marked on the post with a scribing iron. 



At the end of every third mile, wherever possible, a standard iron post of 

 the type recently adopted by your department was planted. At these iron 

 posts two pits were dug, and the earth from the pits was formed into two square 

 pyramidal mounds, in the manner described in the general instructions relating 

 thereto. In some cases it was impossible to plant an iron post and dig the pits 

 and erect mounds, on account of the end of the mile coming in water or on 

 unsuitable ground. In each of such cases, a standard iron post surrounded by 

 a witness trench and accompanied by a conical mound was planted at the nearest 

 even chain where suitable ground could be found, from the correct position of 

 the point to be established. 



These witness posts, trenches and mounds were placed at the following 

 points: — 



At 14 M. 76.00 chains to indicate the 15th mile. 



" 17 M. 73.00 " " 18th mile. 



" 21 M. 8.00 " " 21st mile. 



" 26 M. 62.00 " " 27th mile. 



On the third meridian no iron post was planted at the third mile, on account 

 of the ground being unsuitable, but a witness post was planted at 3 M., 60.00 

 chains, near the shore of Lake St. Joseph. ^*
