May, 1923) The Canadian Field-Naturalist 82 lake with an ebb tide it is necessary to portage. The river is not navigable for motor boats at any time. High tides ascend the river about three- quarters of a mile, but rarely reach the lake, which is twelve feet above sea level. This picturesque lake occupies a narrow, cres- cent-shaped valley approximately twelve miles long and varying between one-half and three- quarters of a mile in width. The water is clear and very deep—over 900 feet has been found in several places—and rocky timbered mountains, the conifers being represented. Western red cedars of venerable age stand solitary amongst the more abundant western hemlock and Douglas fir—of lesser girth but dwarfing the cedars in height. Sitka spruce, western white pine and Amabilis fir are also fairly common and occasionally a small yellow cypress is met with. A few hard- woods near the lake shore, notably some ancient broad-leaf maples, have their rough bark hung with vivid green moss and ferns as have many of the larger conifers. Sitka alder, Oregon crab.

Henderson Lahe—Looking South from Hatchery rising precipitously, form its shore-line. At the south end of the lake these mountains are approxi- mately fifteen hundred to two thousand feet high; northward they increase in height and ruggedness. The head of the valley is overshadowed by lofty peaks, probably five thousand feet high, which were snow-capped when I first saw them on November 11th. They shut out much of the sunlight in the winter months and when the body of the sun drops behind this rampart, which it does before noon, the air is immediately chilled. A small clearing in a narrow timbered flat at the north end of the lake is occupied by the Dominion Government Fish Hatchery buildings, Ternau Creek, a small stream, from which comes the water used in the Hatchery, enters the lake at this point and a quarter of a mile to the east at the edge of the valley and in the north-east corner of the lake is the outlet of Clements Creek, a stream of considerable size. The flat is covered with dense tangled forest of the region, most of apple and willow constitute the balance of the deciduous timber. The floor of the forest is piled high with a confusion of wind-falls, the interstices often choked with devil's club, huckleberry and salmon-berry. The ground and much of the wind-fallen timber are deeply insulated with moss and a luxuriant growth of ferns of various species is general. On the surrounding hills the pre- dominating tree appeared to be Douglas fir on the lower portions succeeded by lodge-pole pine near the summits. The local annual precipitation is about 110 inches and rains are torrential. After an hour's deluge every' hill is lined with silvery cascades of water, dashing into foam over the smooth rocks and conspicuously white between the serried ranks of firs, even in the murk and fog of a rain storm. These streams increase rapidly in volume as the rain continues and the accompanying noise, at first a murmur, grows to a dull insistent roar which dominates all other sounds.
