In the spring of 1848 a party of officers obtained leave to visit Popocatapetl, the highest volcano in America, and to take an escort. I went with the party, many of whom afterwards occupied conspicuous positions before the country. Of those who "went south," and attained high rank, there was Lieutenant Richard Anderson, who commanded a corps at Spottsylvania; Captain Sibley, a major-general, and, after the war, for a number of years in the employ of the Khedive of Egypt; Captain George Crittenden, a rebel general; S. B. Buckner, who surrendered Fort Donelson; and Mansfield Lovell, who commanded at New Orleans before that city fell into the hands of the National troops. Of those who remained on our side there were Captain Andrew Porter, Lieutenant C. P. Stone and Lieutenant Z. B. Tower. There were quite a number of other officers, whose names I cannot recollect.

At a little village (Ozumba) near the base of Popocatapetl, where we purposed to commence the ascent, we procured guides and two pack mules with forage for our horses. High up on the mountain there was a deserted house of one room, called the Vaqueria, which had been occupied years before by men in charge of cattle ranging on the mountain. The pasturage up there was very fine when we saw it, and there were still some cattle, descendants of the former domestic herd, which had now become wild. It was possible to go on horseback as far as the Vaqueria, though the road was somewhat hazardous in places. Sometimes it was very narrow with a yawning precipice on one side, hundreds of feet down to a roaring mountain torrent below, and almost perpendicular walls on the other side. At one of these places one of our mules loaded with two sacks of barley, one on each side, the two about as big as he was, struck his load against the mountain-side and was precipitated to the bottom. The descent was steep but not perpendicular. The mule rolled over and over until the bottom was reached, and we supposed of course the poor animal was dashed to pieces. What was our surprise, not long after we had gone into bivouac, to see the lost mule, cargo and owner coming up the ascent. The load had protected the animal from serious injury; and his owner had gone after him and found a way back to the path leading up to the hut where we were to stay.

The night at the Vaqueria was one of the most unpleasant I ever knew. It was very cold and the rain fell in torrents. A little higher up the rain ceased and snow began. The wind blew with great velocity. The log-cabin we were in had lost the roof entirely on one side, and on the other it was hardly better then a sieve. There was little or no sleep that night. As soon as it was light the next morning, we started to make the ascent to the summit. The wind continued to blow with violence and the weather was still cloudy, but there was neither rain nor snow. The clouds, however, concealed from our view the country below us, except at times a momentary glimpse could be got through a clear space between them. The wind carried the loose snow around the mountain-sides in such volumes as to make it almost impossible to stand up against it. We labored on and on, until it became evident that the top could not be reached before night, if at all in such a storm, and we concluded to return. The descent was easy and rapid, though dangerous, until we got below the snow line. At the cabin we mounted our horses, and by night were at Ozumba.

The fatigues of the day and the loss of sleep the night before drove us to bed early. Our beds consisted of a place on the dirt-floor with a blanket under us. Soon all were asleep; but long before morning first one and then another of our party began to cry out with excruciating pain in the eyes. Not one escaped it. By morning the eyes of half the party were so swollen that they were entirely closed. The others suffered pain equally. The feeling was about what might be expected from the prick of a sharp needle at a white heat. We remained in quarters until the afternoon bathing our eyes in cold water. This relieved us very much, and before night the pain had entirely left. The swelling, however, continued, and about half the party still had their eyes entirely closed; but we concluded to make a start back, those who could see a little leading the horses of those who could not see at all. We moved back to the village of Ameca Ameca, some six miles, and stopped again for the night. The next morning all were entirely well and free from pain. The weather was clear and Popocatapetl stood out in all its beauty, the top looking as if not a mile away, and inviting us to return. About half the party were anxious to try the ascent again, and concluded to do so. The remainder--I was with the remainder--concluded that we had got all the pleasure there was to be had out of mountain climbing, and that we would visit the great caves of Mexico, some ninety miles from where we then were, on the road to Acapulco.
