this point. Fleming Creek, heading in Big Loon Lake, 3Yz miles east of Wright Bay and flowing through Flem- ing Lake to Trembleur Lake, with tributaries, drains the area, An extensive valley, with lakes and rivers, trending in similar north-west direction between the Stuart and Babine Lake systems, reaches from head of Stuart Lake and west end of Trembleur Lake to near Manson Creek Trail, about 70 miles in length, for greater part drained by two forks of Sakeniche River, emptying to Takla Lake opposite the Narrows. The two forks unite in Natowite Lake, to which they flow in reverse directions, and united force a passage through the Middle River Mountains. The northern fork, unexplored, crosses Manson Trail at Long Bridge and extends through a series of minor and larger lakes to Natowite Lake, with at least one large lake, known to Indians as Nakinilerak, east of and paralleling Morrison Lake about equi-distant between Morrison Lake and the North-west Arm of Takla Lake. Indian trappers have canoes on this and Natowite Lake. The southern fork drains through Tochcha Lake, 12 miles long, trending north-west, straight and narrow, and 6 miles farther down the valley is Klaytahnkut Lake, separated from Tochcha Lake by an imperceptible divide and draining in the opposite direction by Tyldesley Creek, a large stream flowing south-west from Middle River Range to Klaytahnkut Lake, thence south-east to Trem- bleur Lake. The valley cleavage continues in same direc- tion to North Arm of Stuart Lake, which forms part of it. Between Tochcha and Klaytahnkut Lakes are some good meadows, 300 to 400 acres. There seems to be a fairly extensive pine-covered flat Between Tochcha and Nato- _ wite Lakes, but soil is gravelly and poor at southern end where examined. Northern part of east shore of Tochcha Lake is burnt over and timber small, but there is a certain amount of spruce around other parts. East of this lake is Deescius Mountain, 2,300 feet above the lake, a bare rocky ridge, east of which is a valley drained by a stream bending sharply westward around Deescius Ridge and pass- ing through many meadows in the main valley to east end of Tochcha Lake. At the bend this stream is within a mile of Tyldesley Creek just above where it enters Klay- tahnkut Lake. Many meadows occur in the valley east of Deescius Ridge toward headwaters of Gloyazikut Creek, but they are rather swampy. East of this valley and between it and Takla Lake and Middle River is Middle River Range, broken, rugged, seemingly of recent volcanic origin. The main range, closely following Middle River, is divided by a valley south of Pyramid Peak. The northern part, known as Tsitsult, appears of serpentine formation and traces of asbestos are noted in several places. The southern part, Mount Williams, has as its high peak an extinct volcano, with a 16
