about 25 miles north of Fort Grahame. Fox River is navigable with difficulty for 23 miles above its mouth. From Fort Ware a good pack-horse trail runs northward along Fox River to Sifton Pass, elevation 3,273 feet; thence down Kechika River to the junction of the Turnagain River. There the trail crosses to the west side of the Turn- again and continues through to Lower Post on the Liard. From Lower Post boats may be taken down the Liard River to the mouth of the Turnagain River, up the Turn- again to the junction of the Kechika, and then up the Kechika to Driftpile Creek, only 5 miles north of Sifton Pass. The Turnagain is navigable for only a few miles above its junction with the Kechika. From the Trench at Chee House, at the mouth of Kechika River, an old pack-horse trail crosses the mountains to Muncho Lake, and formerly ran through to Fort Nelson. A second trail crosses the Rocky Mountains, running from Fort Ware up Kwadacha River; thence through the mountains to the head of the Muskwa River where it joins a pack-horse trail, used by hunting parties, that runs northward from the Peace River. It is possible to travel westward from the Trench along several routes. The Ingenika River is navigable by boat for 30 to 40 miles above its mouth. A pack-horse trail runs westward through the mountains up Bower Creek to Fishing Lake; thence farther west to connect with a trail running through to Telegraph Creek. Another trail runs up Turnagain River, from its junction with the Kechika to Deadwood Lake, whence one branch trail leads to McDame Creek and the other continues up to the head of the Turnagain River and through to Dease Lake. The Alaska Highway affords access to a considerable area not readily reached formerly. The Alaska Highway starts at Dawson Creek, the northern terminus of the Northern Alberta Railways, about 500 miles by road from Edmonton. Dawson Creek will soon be connected to Prince George by a highway, now under construction, that runs through the Rocky Mountains by way of Pine Pass. From Dawson Creek the highway runs 49 miles north to Fort St. John; thence a further 256 miles northward along the east side of the Rocky Mountains to Fort Nelson at the junction of the Muskwa and Fort Nelson Rivers. From Fort Nelson the highway runs west- ward up the Muskwa and Tetsa Rivers to Muncho Lake, and down Trout River to the Liard River bridge at Mile 210 from Fort Nelson. From the Liard River bridge the highway runs along the north side of the river to Lower Post; thence westward to Teslin Post on the east side of Teslin Lake. The highway between Lower Post and Teslin Lake is close to the north-eastern side of the Cassiar Mountains. Another route, used to gain access to the Cassiar Mountains, is by way of coast steamship to Wrangell, Alaska; thence up the Stikine River to Telegraph Creek, the head of navigation. From Telegraph Creek a pack-horse trail runs east and south, making it possible to take pack-horses through along the western flank of the mountains to the head of Takla Lake. A truck-road runs from Telegraph Creek to the head of Dease Lake, whence boats may be taken down Dease Lake and Dease River to Lower Post. Lower Post is on the Alaska Highway, about 650 miles from Dawson Creek. In the Omineca area a road runs 140 miles north from Fort St. James to Ger- mansen Landing on the Omineca River, whence a winter road has been cut through to Aiken Lake, about 95 miles farther north. For many years Fort St. James, on Stuart Lake, has been the base for aircraft available for charter. Pontoon-equipped aircraft are used for landing on the numerous lakes that dot Northern British Columbia. Few places in North-eastern British Columbia lie any great distance from a suitable lake. Prospectors have been amongst the first to realize the advantages of air transport. Undoubtedly increased use will be made of aircraft for local transportation now that landing-fields have been built at Prince George, Fort St. John, Fort Nelson, and Watson Lake, and regular air services have been established.
