of it on July 6th. From here we moved to Opeepeesway Lake, finishing this 

 survey on July 15th. 



On July 16th, we moved camp about half-way to Kukatush and arrived 

 there on July 17th. 



On July 19th, we commenced the survey of Ground Hog River. Having 

 more trouble with men, I sent Bourke to North Bay for others. Bourke was 

 unable to get men, but I finally got two in Sudbury. We finished survey of the 

 Ground Hog River on August 17th. 



The party was then moved by train to Trout River, which was finished 

 on September 4th. Camp was then moved to the north boundary of Kapus- 

 kasing township and the survey of Kapuskasing River commenced. This was 

 the final survey of the year, and was completed and the last men paid off on 

 September 30th. 



The following is the mileage of the traverse: 



Miles 



Kasaswaychin, Katagi, Atekepemeska and Arbeesee Lakes 60.0 



Rice Lake 44.0 



Opeepeesway Lake , 39.0 



Sahkatawichtah Lake 4.0 



Ground Hog River 87.0 



Trout and Kapuskasing Rivers 97.0 



Total 331.0 



2. — Method of Survey. 



(a) Instruments Used. — The traverse was made throughout by transit 

 and stadia. Azimuth angles were used and also the angle to the right was 

 measured between stations. The stadia rods used, read direct to tenths of links. 

 The targets were about two feet long by about six inches wide, one being firmly 

 placed at the top of the rod, and the other moved to the correct position by the 

 rodman. A supply of white linen was carried and the targets newly covered 

 from time to time. 



The accuracy of readings was checked from time to time by readings on 

 chained lines and also on the sides of triangles calculated from chained base 

 measurements. They were found to be very accurate. 



(b) Field Notes. — One form of field notes was kept throughout the course 

 of work. The notes were transcribed in ink and carefully checked. They 

 show: station, azimuth, distance, angle right, bearing and, under Remarks, 

 the point on which the reading was taken. 



(c) Observations were taken frequently on Polaris for azimuth. The 

 results are shown in the field notes. 



(d) Posts and Blazed Trees. — Along the banks of the rivers and around 

 the shores of the lakes, trees were blazed at intervals of about one mile and 

 were marked: 1 M., 2 M., 3 M., etc. Records of these are shown on the plans 

 and in the field notes. 



On islands stump posts were made. A good sound tree was felled and the 

 stump squared and marked with a letter, "A," "B," "C," etc., except in some 

 cases when the island was very small, when a tree was blazed. The bearings 

 shown to posts and trees are measured with the transit and are astronomic. 



(e) Survey Lines, Township Boundaries. — In all cases where survey lines 

 were found, they were tied in and are shown on the plans. Posts were planted
