St. Joseph. This portage is about half a mile long, and is much the longest 

 of the ten. The portages are all in good condition, as this route is extensively 

 used by the Hudson's Bay Company for transporting supplies to their posts 

 at Osnaburgh and Cat Lake. The starting point of the survey was about twenty- 

 five miles by the route travelled down Lake St. Joseph from the end of the 

 lake. 



The first base line was started at Mile 60 on the meridian line run by my- 

 self in 1919, being the boundary between the districts of Kenora and Thunder 

 Bay. This base line was run west, astronomically, for a distance of 18 miles. 

 The second base line was started at Mile 66 on the same meridian line, and 

 was also run west a distance of approximately 18 miles. From the 6, 12, and 

 18 Mile on the first base line, meridian lines were run north, astronomically, a 

 distance of approximately 6 miles, to intersect the second base line. These 

 meridians are known as the first, second and third lines, respectively. 



Each base line was run as a series of six-mile chords of a parallel of lati-

tude. The meridian lines were run north-east. These lines were all well cut 

 out and blazed. A substantial wooden post, of the best green timber avail- 

 able, was planted at the end of each mile, except when this point fell in a lake 

 or stream, and was surrounded by a mound of stones wherever possible. Bear- 

 ing trees were marked with the letters, "B T," after being blazed in a prominent 

 manner, at every post where possible, and the bearings and distances of these 

 trees from the various posts 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 started. Where 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, pits were dug and the earth from these was formed into two square pyr- 

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