course, holding to the left of the main peak,led us over moderate slopes, for some miles, until, passing one or twosmall ponds, with no outlets, we struck the foot of the spur which, run-ning out from the second crest of the Eed Mountain range, countingfrom the north end, forms the divide between Lewiss and YellowstoneLakes. Upon that divide lies the small lake, without outlet, called LakeEiddle,* visited by Dr. Haydens party on their return from the Fire- * Lake Eiddle is a fugitive name, which has been located at several places, butnowhere permanently. It is supposed to have been used originally to designate themythical lake, among the mountains, whence, according to the hunters, water flowedto both oceans. I have agreed to Mr. Herings proposal to attach the name to thislake, which is directly upon the divide at a point where the waters of the two oceansstart so nearly together, and thus to solve the iusolvable riddle of the two-oceanwater.

Mr. Hering visited this lake, and found it to be7,999 feet above the sea, while Lewiss Lake is 7,750 feet and YellowstoneLake is 7,788 feet. A high terrace is faintly indicated on the east sideof Lewiss Lake, but its level was not determined. This region shouldbe more carefully examined, with a view to ascertain whether there isnot some continuous terrace higher than the dividejust described, whichshall proNe that the whole of this broad comparatively flat area was, asits general form suggests, covered by a large lake, which was reallytributary to both oceans. The lowest point of the actual divide wasdetermined to be 25 feet above Lake Eiddle, or 8,024 feet above the sea. In ascending the mountain, we found the easiest slopes very steep, soas to make much zigzagging necessary in getting our animals to thesummit. As we occasionally looked back, we saw beneath us, on ourleft, the large cluster of hot springs which occupi
