backed up the water so as to form a pond on both sides of the 

 embankment. In addition to this the. beaver continually plug up 

 the culvert, I was informed by one of the section crew, so that the 

 men were obliged to tear out the obstruction every day. 



5. Long Lake Region. Round Pond lies east of Long Lake in 

 Township 50 (map 2). Where the southwest inlet creek enters 

 the pond there is a dam which rather recently has flooded and 

 killed several acres of timber extending upstream along the creek. 

 On the northern tributary of this creek are two dams of considerable 

 size, only a short distance apart. The upper one measured 125 

 paces in length and was 1 foot, 6 inches high. A belt of dead 

 timber estimated to be from 12 to 18 rods wide extends upstream 

 from these dams for a distance of about half a mile (figure 16). 



On Pine Brook, a short distance to the north of Round Pond, 

 there is a dam, about a mile distant from Long Lake, which is 

 100 feet long and 4 feet, 4 inches high between water levels; 

 measured from the bottom the dam is 8 feet high. It is situated 

 at a narrow part of the brook, with low ground just above it where 

 a large pond has resulted (figure 17). Beginning with the pond 

 the dead timber, which is rather small, extends upstream for a 

 distance of about a mile. This is cut-over land, and farther up- 

 stream the creek flows through a burned area where beaver dams 

 are of no consequence so far as timber is concerned. 



Entering Long Lake on the east shore, Township 22, lot 50. is 

 an insignificant stream known as " Old Landing Creek." This was 

 explored for a distance of about three miles. Three dams were 

 located, the largest of which was 150 feet long and 5 feet, 3 

 inches high from the bottom. These dams had been torn open 

 on August 18 by Ranger Isaac Robinson and the beaver had as yet, 

 August 26, made no attempt to repair them. Among the many 

 large birches and spruces killed in the ponds were four large pines, 

 the largest measuring 7 feet, 9.5 inches in circumference, waist high. 



On the small stream entering Lake Eaton (locally known as 

 "Clear Lake") from the southwest, and about ten minutes' tramp 

 from the lake, at the junction of two tributaries, is a dam no feet 

 long and 7 feet high at the stream's channel. The pond above 

 covers about one and a half or two acres. The larger trees that 

 have been killed are birches measuring 9 inches to a foot or 

 more in diameter. A number of smaller dams occur on one of the 

 tributaries, but some of them have recentlv been abandoned.
