these languages? We believe that these difficulties even aside from that of making a satisfactory language will prevent the scheme of a universal language being successful.YUKON EXPEDITIONWEnoticed several times the progress of the Yukon expedition undertaken by the Canadian Government in . The present number of Scienceis accompanied by a map showing the results of this important expedition. The map is a reduction of The North Face Outlet Store a largescale map published by the Department of the Interior of Canada a number of corrections being Nike Free Run added by Dr. Dawson. The coastline is founded upon the charts of the Coast Survey. While the greater part of the topography of the interior is the result of last years expedition a few older explorations were available for constructing the map. The lower part of the Stikine River was surveyed inby J. Hunter. The traverse from Telegraph Creek down the Hotalinqua River to latitude Polo Outlet Online o north was made by the Telegraph Exploration in . Schwatkas maps were used for constructing the lower part of Pelly Polo Ralph Lauren Outlet River while Chilkat River is founded on Dr. A. Krauses surveys in .The recent expedition was undertaken in consequence of the necessity of ascertaining the nature and extent of the developmentsof placer goldmining which of late years has attracted an increasing number of miners into that part of the Northwest Territories lying between British Columbia and Alaska. We reported in No.of Scienceon the progress of Dr. Dawsons expedition up to the th of July. Mr. William Ogilvie had reached the lower pan of Pelly River by a different route. He had started from Chilkoot Inlet and reached the summit of Chilkoot Pass on June . On June after considerable difficulty occasioned by stormy weather the first lake was reached. Mr. Ralph Lauren Outlet Ogilvie experienced considerable difficulty in carrying his instrumental survey across the mountains. He says in his report Nike Max Air 90 to Captain DevilleBeginning from the summit of Chilkoot Pass we descend almost onethird of a mile to Crater Lake the fall in that distance being by barometerfeet. At four miles and a half from the summit Mountain Lake which is about a mile and a half in length is reached the fall in this distance being aboutfeet. At this point the first trees on the northeast side of The North Face Outlet the summit are seen Nike Argentina but they are of no importance being small and of stunted growth. Lake Lindeman was found to be feet below Chilkoot Pass. The party then crossed Lake Bennett and Lake Marsh and began their descent of the Lewes River. Atmiles from salt water the canon is reached. At this point the river flows through a fissure in a barrier of basaltic rocks which intersects its course. The canon proper is about fiveeighths of a mile long and aboutfeet wide with perpendicular walls fromtofeet high. The current through it is swift and the water rough; but with a fairly large boat the only risk in running through it would be from contact with the sides in which Nike Free case one North Face Outlet Store would be certain to come to grief. The passage through it is made in from three to four minutes. The canon and its rapids are altogether two miles Nike Shop and threequarters long. The last rapid which is threeeighths of a mile in length is a bad one and we had to portage every thing round it and let our boat down with ropes from the shore. This rapid is called by the miners theWhite Horse from the fact that nearly all the water is white with foam. Several parties have run through the rapid on rafts and oneortwoin North Face Outlet boats. but few want to repeat the trip. In proceeding farther down the river the travellers passed Big Salmon River. Looking up its valley a distant view was had of many mountainpeaks covered with Ralph Lauren Outlet Online snow the presence of which in summer is proof of a considerable altitude. Ogilvie found that the upper part of the river was almost deserted by the miners who have gone to FortyMile Creek where considerable quantities of gold have been found.Dr. Dawson who Nike Max Air
