1919-20 DEPAETMENT OF LANDS, FORESTS AND MINES. 89 



The stadia rods used read direct to tenths of links. The accuracy of readings 

 was checked from time to time by readings on measured lines and also on the 

 sides of triangles, calculated from chained base measurements. They were found 

 to be very accurate. Eesults are shown in the field notes. 



Field Notes. 



(6) One form of field notes was kept throughout the course of the 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, — Observations were taken frequently on Polaris and the sun 

 for azimuth. The calculations are shown in the field notes. 



(d) Posts and blazed trees. — On rivers and around the shores of 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 a few cases 

 where the islands were very small, when a tree was blazed. The bearings shown 

 to posts and trees are astronomical. 



(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 one 

 chain from the shore on each side of the river or lake, where this had not been 

 done in the original survey. 



At the south end of Pishkanogama Lake, on the Avest side, we found what 

 appears to be the production across the lake of O.L.S. Sinclairjs line, run in 

 1867. We tried to find more blazed trees by turning an azimuth of 90 degrees, 

 but the others seemed to have been burned as it is a very old brule at this point. 

 The tree we found is a fourteen-inch cedar, blazed on three sides and marked 

 " IXMIX." The wood grown over the blazes seems to be about 32 years old 

 and the cedar has been dead probably 20 years. 



Descriptions of Lakes and Rivers. 

 (a) OpazatiJca River and Lakes. 



Shores. — Opazatika River has an average width of about two chains. The 

 sliores are clay, except in a few places where rock outcrops. The land back from 

 the banks is nearly all an old brule grown up with poplar of from three to four 

 inches in diameter down to mere brush. The soil is a good clay loam very 

 suitable for agriculture, and very easily cleared at present while this growth 

 is small. 



The shores of Rufus, Penelton and Opazatika Lakes are rocky and, as the brule 

 extends here also, there is very little valuable timber. 



Water Powers. — There is only one falls of real value from a power viewpoint. 

 This is on the Opazatika River at the eleventh mile post of the traverse, south 

 of McCrea Township. 



Owing to wind I was unable to get the flow measurement. The head is 

 23.7 feet. 



One hundred and sixty acres should be quite sufficient land for development 

 purposes. The two snapshots shown below are of this falls.
