1916-17 DEPAKTMENT OF LANDS, FORESTS AND MINES. 81 



Rook Formation. 



The rock of the south boundary is all granite with an occasional small belt oi 

 diabase running through it, this formation appears to continue on the east bound- 

 ary to the south side of the lake on the 36th mile; from the north side of this lake 

 the Keewatin formation predominates up to the 57th mile where the granite comes 

 in again for about four miles, then the formation is Keewatin with small belts of 

 diabase up to the 65th mile where granite occurs again and continues up to about 

 the end of the 68th mile. From here to the end of the line the rock is principally 

 Keewatin with belts of diabase. From the 83rd mile northward there is con- 

 siderable local attraction (the maximum noted was 39 degrees west on the 84th 

 mile) indicating the presence of iron-bearing rocks. 



Timber. 



The principal timber throughout almost the entire line is spruce. On the 

 south boundary for the first six miles the growth is thick and small and there is 

 no timber of any value. This occurs again on the 9th and 11th miles; also on the 

 east boundary, on the 89th to the 93rd miles the timber is small and thick and con- 

 sists principally of birch, poplar and jack pine. With these exceptions, however, 

 the country is well wooded with spruce, balsam, birch and some jack pine from 

 3 to 18 in. on the south boundary and for about six miles north on the east,|3pund- 

 ary where the poplar is present more frequently and the timber is somewhat larger 

 from this point north, the largest timber being about 24 inches in diameter, but 

 averaging from 5 to 8 inches. On the northerly half of the east boundary the 

 muskegs and swamps occur more frequently, but the timber on the high ground 

 remains the same with a few exceptions. In the swamps some cedar is met with 

 but it is usually of a short, scrubby growth, the principal timber in the swamps 

 being spruce, usually small, and dead tamarac. Some jack pine of sufficient size 

 to be of value occurs on the 34th and 35th miles, the 39th, 40th and 41st miles, the 

 olst and 52nd miles, and some slightly smaller in size on the 96th mile. 



The recently burned areas are small and occur on the 35th and 36th miles, the 

 56th mile, the 77th to the 79th mile, while a fire of comparatively recent date has 

 been over the country from the north side of Lily lake to the 94th mile. 



Game, Etc. 



Moose, deer and caribou are plentiful along the south boundary and the south- 

 erly part of the east boundary, but farther north, while present, they do not appear 

 to be as numerous. 



On the south boundary and north on the east boundary as far as about the 30th 

 mile, beavers are very numerous, but from this point up to the 49th mile none of 

 their work was seen ; from this point they are absent again up to that part of the 

 east boundary north of the 81st mile where they appear again. 



The only kinds of fish seen or caught were pike, pickerel and whitefish. ., The 

 waters of the lakes up to the lake at the 37th mile, while having no disagreeable 

 taste, are dark in colour, but this lake and most of those north of it are clear, but 

 notwithstanding this no trout were seen or caught.
