As Lieutenant Gracie is obliged to remain at this camping ground, and it may be some days before the command arrives from the Dalles, I have determined myself to proceed on to that post to-morrow in company with Mr. McKay. I therefore this evening rode over to his place and made my arrangements for setting off the next morning. _Wednesday, June 20th._—This morning a messenger arrived from the Dalles with papers and the latest news—the latter having been almost forgotten by this time in the settlements. After early drill I took my final leave of the camp. Lieutenant Gracie rode with me over to Mr. McKay's, where I left my horse, as he belonged to the command, transferring my saddle and bridle to one of Mr. McKay's, which I am to ride. And here Lieutenant Gracie and I parted. We have been companions for weeks by day and night, and in this his first independent command, (in many incidents which I could not relate in this brief journal,) he has established, with those at the Council who were accustomed to military expeditions in the Indian country, a character for decision and energy which gives the promise of distinction in much wider and more responsible scenes of action in the future. We set off about half-past nine o'clock. Mr. McKay and myself, with two boys whose business was to drive the pack mules. Our traveling arrangements were made in the old Spanish-California style, still common in those parts of the country where horses are plenty. Besides those we rode, were seven or eight which ran loose and were driven by the boys, to be used when our own began to flag. We crossed the Umatilla at once, and on the opposite side striking the trail on which we had gone into the interior, commenced our return westward. After riding for about twenty miles we reached the Indian Agency. Here, two of the other horses were caught, our saddles and bridles transferred to them, and the tired ones turned loose to follow with the rest. Then, on we went until five in the evening when we encamped for the night at Wells' Springs, having traveled during the day fifty-five miles. _Thursday, June 21st._—We were on our way this morning by five o'clock. On the trail we passed every little while solitary graves, the last resting places of some unfortunate emigrants. The road from Missouri to the Rocky Mountains can almost be traced by these sad memorials, and no human language can convey an idea of the sorrow and suffering which has taken place on the plains, caused by this rush to the land of gold. About ten miles on our way we met a portion of the 4th Infantry and 3d Artillery under Lieutenants Day, Hodges and Mendell. At noon we halted at Willow Creek, (seventeen miles from Wells' Springs,) for several hours, to rest our horses. We then pushed on until eight in the evening, when we reached John Day's River, where a refreshing bath recompensed us for our long and hot ride. We had ridden to-day about forty-five miles.
