The majestic mountain of Orizaba, or Citlaltepetl, the "Mountain of the Star," is found within the limits of the State of Vera Cruz, and as it is somewhat renowned in all geographical descriptions of this continent, we shall insert the first authentic account of its ascent we have ever seen, which was prepared by Lieutenant W. F. Reynolds, of the United States Topographical Engineers, who, with some friends, reached the lofty peak whilst serving with our army in Mexico.

"The Peak of Orizaba," says he, "though situated nearly a hundred miles in the interior, is the first land beheld on approaching Vera Cruz from the gulf. Being visible nearly fifty miles at sea, it is the most important land mark to the sailor in these regions. While the command under General Bankhead, which was the first to march from Vera Cruz to the city of Orizaba, was 'en route,' in February, 1848, the mountain being constantly in view, a trip to its summit was frequently discussed; and after our arrival at that place, the marvellous stories told by the inhabitants only increased our desire to make the attempt. All agreed that the summit had never been reached, though several knew or heard of its being attempted. The difficulties to be encountered were represented as being perfectly insurmountable; craggy precipices were to be climbed; gullies, two thousand feet deep, it was said, were to be crossed; inclined planes of smooth ice were to be ascended; to say nothing of avalanches, under which, we were assured, all the rash party who made the daring attempt would surely find a grave. These extraordinary stories produced quite a different effect from the one anticipated, and the question was not who would go, but who would stay home. It was not, however, till the latter part of April that the weather was thought favorable, and securing, for the proposed expedition, the sanction of the commanding officer, we made our preparations for overcoming all obstacles. Accordingly, long poles were prepared, shod with iron sockets at one end and hooks at the other, to assist in scaling precipices; ropes with iron grapnels were to be thrown over a projecting crag or icy point; rope ladders were made to be used if required; shoes and sandals with sharp projecting points to assist in climbing the icy slopes, were also bespoken;—in short, everything that was thought might be needed or would increase the chances of success, was taken along. The selection of a route presented some difficulty, different ones being recommended—those by San Andres and San Juan de Coscomatepec particularly. In order to decide between them, we endeavored to persuade some of the intelligent citizens who were acquainted with the country, to go with us. At first they consented, but as the time approached one after another declined, till finally, when the party assembled for starting, it was found we were to go alone. Then, as some inclined to one route and others to another, we concluded to reject all their recommendations, and go direct to the mountain, following the path taken by the Indians engaged in bringing down snow to the city, as far as the limits of vegetation, and from that point to go round the peak to the side that would present the best prospect for success.

"We left the city of Orizaba on the morning of the 7th of May, the party consisting of ten officers, including one of the navy, thirty-four soldiers, and two sailors serving with the naval battery, three or four Mexicans and Indians as guides, and enough pack mules to carry our provisions and equipments. Our expedition setting out during the armistice, it was thought advisable to procure a passport from the prefect of Orizaba to provide against exigencies. About six miles from the city of Orizaba we passed through the small Indian village of La Perla; the inhabitants were much frightened at our approach, but our passport soon quieted them, and when they came to know the object of our visit, they seemed to regard us as the greatest set of donkeys they ever saw, telling us very plainly that we could never reach the summit. Nothing daunted, however, we continued on, and immediately after leaving the village commenced a rapid assent, and began to enjoy views which in themselves would have amply repaid us for our trouble. We encamped for the night at an elevation of 7,000 feet above the level of the sea; the night was clear and bracing, but not cold enough to be uncomfortable. The next morning was beautiful and clear, and after an early breakfast, we were again in motion. The scenery was truly sublime, and ascending one mountain after another, valley after valley appeared in view; hills which at first seemed mountains, seemed gradually sinking before our feet, and the range of vision constantly extending, we could not help making frequent halts to admire scenes which cannot be surpassed, and which at every successive turn broke upon our sight with redoubled magnificence and grandeur. We were now in the region of pines and northern plants; the old familiar oak, the birch, and trees unknown to the lower countries, were around us; the heavy undergrowth had disappeared, and we could almost imagine ourselves in our 'dear native land.' Cultivation does not extend up as high as we expected to see it; we passed the upper limit about 8,000 feet elevation. About 12 o'clock, and at an elevation of rather more than 10,000 feet, the guides reported that the mules could go no farther, and not knowing anything of our route beyond, we were compelled to encamp for the night. A brother officer and myself, however, being on horse-back and feeling comparatively fresh, determined to go forward and explore. We concluded that it would not do to stop where we were, but the mules with light loads could go still higher. Accordingly, next morning we again started, four or five of us going in advance to select a good place for encampment, and also to explore the best route for the final ascent. We selected our camp on the verge of vegetation, and went forward by routes far above the line of eternal snow. Under shelter of a rock, and far above that line, some of the party found a rude cross, decorated with paper ornaments and surrounded by tallow candles. Its history we were unable to learn, but it gave rise to many reflections. Who placed it there? when was it erected? and what event did it record? were questions asked, but not answered. During the trip several parties of Indians passed us, who make a regular business of bringing down snow on their backs to the citizens of Orizaba. The cross was probably erected by some of them. On our return, we found all our baggage brought up to the new encampment, notwithstanding it had been pronounced impossible, and on comparing notes, selected the route which seemed most practicable, and prepared for the ascent in the morning. The night was clear and cold, the thermometer falling below the freezing point; a heavy frost and frozen water reminding us forcibly of 'auld lang syne.' While sitting round our camp-fires this evening, it was discovered that there were two flags in the party; the sailors not knowing that one had been brought along, had carried materials and manufactured one in the camp. It was proposed to get up a rivalry as to which flag should be planted first, but we came to the conclusion at last, that should the summit be reached, the honor should be equally shared. As night came on, we enjoyed a most magnificent sight; the clouds gathered round the foot of the mountain so as to entirely obstruct our view, while the distant lightning flash, darting from cloud to cloud, was visible far beneath our feet; the sky overhead being bright and beautiful. We were encamped at an elevation, according to the barometer, of 12,000 feet, about double that of the highest peak of the White Mountains—while the summit still raised its snow-white head above us to a height nearly equal to that of Mount Washington above the sea, and seemed to frown upon the pigmies who dared to attempt to scale its giddy, and, as yet, unascended height. At daylight on the morning of the 10th of May, we were again in motion; many of the party had already given out, so that there were but twenty-four persons to start on the final journey. In a few minutes we were at the foot of the snow, and taking the route over which there seemed to be the least of it, passed for half or three-fourths of a mile over loose volcanic sand. On measuring the slope of this, I found it to be 33°. It was by far the most difficult portion of our ascent;—sinking up to our knees in sand, we seemed to go back about as far as we stepped forward, while the rarefied condition of the atmosphere made exertion painful in the extreme; indeed, during the whole of this day's ascent, it was impossible to advance fifty paces without stopping to take breath. When not exerting ourselves, we could breathe with comparative ease; but the moment we moved, we were reminded of our great elevation. I can only compare the sensation to that felt by a person who, after running at the top of his speed, is ready to sink down from sheer exhaustion.

"At length, however, we reached firm rock, and it was quite a relief to be able once more to climb with our hands and feet. But we were yet far from the point at which we were aiming, and before reaching it were to be many times sorely disappointed. A projecting crag, far above, would be hailed as the summit; step after step the weary body was dragged along, until at length it was reached; but, once there, it was found to be but the base of another still higher;—this, too, being overcome, another was discovered above. Thus, time after time, were our expectations crushed, till hope seemed almost to have forsaken us, and one after another dropped behind in despair. But—'advance'—was our motto, and onward we pushed, until at length the efforts of some of the party were crowned with success, and they dropped exhausted on the brink of the crater.

"The crater is nearly circular and variously estimated by different members of our troop at from 400 to 650 yards in diameter. We all estimated the depth at 300 feet. The sides are nearly vertical, and show strong and unmistakeable signs of fire, looking like the mouth of a gigantic furnace.

"At the foot of this perpendicular wall was quite a bank of sand or débris, which had fallen from the inner surface of the rock, indicating the great length of time since the volcano had been extinct. Indeed its fires were perfectly dead, for the bottom of the crater was covered with snow. Humboldt says its most violent eruptions were in 1545 and 1566,—nor have I seen a record of an eruption since.

"As I desired to test Humboldt's altitude, I had taken the precaution to be as well prepared as circumstances would admit, and accordingly had carried with me the best barometer I could get, which, from previous calculations, I deemed capable of indicating a height of from 300 to 400 feet higher than that given by him. I had, also, provided myself with a spirit-lamp and thermometer, for the purpose of taking the temperature of boiling water; but, on the march, the bottle containing the alcohol was broken and the spirit entirely lost. I therefore determined to test the combustible qualities of whiskey. One of my first objects after reaching the summit was to make observations; but, on preparing the barometer, the mercury sank at once below the graduation.

"I estimated the distance between the lowest line of graduation and the top of the mercury at two-tenths of an inch, which gives,—with corresponding observations in the city of Orizaba at the same hour,—an elevation of 17,907 feet, and makes it the highest point on the North American Continent. I do not think I could have been far wrong in my estimate, as the means of comparison were before me; but, even supposing I was mistaken one-twentieth of an inch, we still have an elevation of 17,819 feet, 98 feet higher than Popocatepetl, which is usually considered the highest point,—5,400 metres, or, 17,721 feet, as given by Humboldt.[51] The temperature was just below freezing point. My attempt to burn whiskey failed. Since my return to the United States, I have observed that Humboldt states that Mr. Ferrar measured Orizaba, eight years before his arrival in Mexico, and gave the mountain an elevation of 5,460 metres or 17,885 feet. Humboldt's measurement, made from a plain near Jalapa, is 155 metres less, or 17,377 feet in all. It will be seen that my determination agrees very nearly with that of Mr. Ferrar.

"We remained on the summit about an hour,—planted our national banner and saluted it with three hearty cheers. The day was clear, but the atmosphere thick and smoky, so that we did not enjoy the views we had hoped for; but as we believed ourselves to have been the first who ever looked into the crater, we were amply repaid for our trouble.

"The descent was by no means so difficult as the ascent; a slide on the snow or sand carried us hundreds of feet down a space which had required many weary steps to ascend. About dark we arrived at our encampment, highly delighted with our trip, though much exhausted. All who made the final attempt were more or less affected either with violent headaches, nausea, and vomiting, or bleeding at the nose. The veils which we provided for our journey did good service, but the face, and particularly the lips, of all who reached the summit, became so extremely swollen and cracked as to confine them to their rooms for several days.
