He seated himself before the roaring sheet of water, and endeavored to put a description of it upon paper; but then he added helplessly:-- "After wrighting this imperfect description I again viewed the falls and was so much disgusted with the imperfect idea which it conveyed of the scene that I determined to draw my pen across it and begin agin, but then reflected that I could not perhaps succeed better than penning the first impressions of the mind; I wished for the pencil of a Salvator Rosa, or the pen of a Thompson, that I might be enabled to give to the enlightened world some just idea of this truly magnificent and sublimely grand object, which has from the commencement of time been concealed from the view of civilized man; but this was fruitless and vain. I most sincerely regreted that I had not brought a chimeeobscura with me by the assistance of which I could have hoped to have done better but alas this was also out of my reach; I therefore, with my pen only endeavored to trace some of the stronger features of this seen by the assistance of which and my recollection aided by some able pencil I hope still to give to the world some fain idea of an object which at this moment fills me with such pleasure and astonishment." On the next day he went ahead, alone, and discovered that this was but the first of a long series of cascades, extending for many miles up the canyon. It was a day of excitement. While returning to rejoin his party, he suffered his gun to remain for a time unloaded; in this plight he was surprised by a grizzly bear. Cut off from any other retreat, he was forced to take to the water, in which he stood to the depth of his armpits, facing the brute upon the bank and preparing to defend himself in a hand-to-hand struggle; but, in a manner wholly out of keeping with his family traditions, the grizzly was content to walk away without attacking. Proceeding about nightfall, the young officer encountered a strange beast, probably a wolverine, which showed fight; and a little later he was charged by three bulls from a herd of buffalo. Upon waking the next morning, he found a large rattlesnake coiled about the trunk of the tree beneath which he had slept. CHAPTER VII OVER THE CONTINENTAL DIVIDE A messenger was sent back to Captain Clark, detailing what had been discovered, and giving such instructions as would best enable him to bring up the boats. It is now Captain Clark's turn to bear testimony to the spirit of the men:-- "June 15th.... Proceeded with great difficulty, in consequence of the increased rapidity of the current. The channel is constantly obstructed by rocks and dangerous rapids. During the whole progress, the men are in the water holding the canoes, and walking on sharp rocks and round stones, which cut their feet or cause them to fall. Rattlesnakes are so numerous that the men are constantly on their guard against being bitten by them; yet they bear the fatigues with the most undiminished cheerfulness."
