The roads by degrees assumed an Alpine character; in some places the declivity was so great, that the mules could scarcely keep their footing, while in others the acclivity was equally difficult. Occasionally the road grew so narrow that there was scarcely room for the mules to pass, while it lay at other times along the edge of tremendous precipices, where, had they made one false step, they must have inevitably toppled over and perished. The extraordinary dexterity of the mules in descending the fearful slopes of these mountains is one of the most surprising things related of the sagacity of animals. The mules themselves are sensible of the caution requisite in these descents; for coming at the top of an eminence they stop, and having placed their fore-feet close together, as in a posture of stopping themselves, they put their hind-feet together, but a little forwards, as if going to lie down. In this attitude, having taken a survey of the road, they slide down with the swiftness of a meteor. All the rider has to do is to keep himself fast on the saddle without checking the beast; for the least motion is sufficient to disorder the equilibrium of the mule; in which case they both unavoidably perish. The address of these creatures is here truly wonderful; for in this rapid motion, when they seem to have lost all government of themselves, they follow exactly the different windings of the road, as if they had before accurately reconnoitred, and previously settled in their minds the route they were to follow, and taken every precaution for their safety among so many irregularities. There would indeed otherwise be no possibility of travelling over such places, where the safety of the rider depends on the experience and address of his beast.

But the longest habit of travelling these roads cannot entirely free them from a kind of dread or horror, which appears when they arrive at the top of a steep declivity; for they stop without being checked by the rider; and, if he inadvertently endeavours to spur them on, they continue immoveable, nor will they stir from the place till they have put themselves in the above-mentioned posture. Now it is that they seem to be actuated by reason; for they not only attentively view the road, but tremble and snort at the danger which, if the rider be not accustomed to these emotions, cannot fail of filling him with terrible ideas.

On the 18th they crossed the summit of the mountain, and descended into the province of Chimbo, where they were met by the corregidor, the provincial alcalde, and the principal persons of the town; and on their nearer approach a number of Dominican monks, with a large portion of the inhabitants, came out with a troop of Indian dancing and singing boys to welcome them. Here they remained three days to refresh themselves after their fatiguing passage across the mountains; and then, continuing their journey, entered the desert of Chimborazo, keeping the mountain of the same name on the left, and travelling, over different eminences and heights, most of which were of sand, the snow for a great, distance forming, as it were, the sides of the mountain. During their journey across this desert they suffered greatly from the cold, the severity of which was much increased by the violence of the wind. They lodged at night in caverns in the rock; and on emerging from the more dreary part of the waste, passed the ruins of a palace of the ancient incas of Peru.

On their arrival at Quito, they were received with splendid hospitality by Don Dioneso de Alzedo y Herrera, who provided them with apartments in the palace of the Andencia, while the clergy and the principal inhabitants vied with each other in their attention and civilities. Among the many remarkable natural curiosities observed by our traveller during his journey is a species of cane, from thirty-five to fifty feet in height, and about six inches in diameter. “From the time of their first appearance till they attain their full perfection, when they are cut down or begin to dry, most of the tubes contain a quantity of water; but with this remarkable difference, that at full moon they are entirely or very nearly full, and with the decrease of the moon the water ebbs, till at the conjunction little or none is found. I have myself cut them at all seasons, so that I here advance nothing but what I know to be true from experience. I have also observed that the water during the decrease appears turbid; but about the time of the full moon it is as clear as crystal.”

The travellers had spent one whole year in reaching Quito, and the first few days after their arrival were necessarily devoted to rest and an exchange of civilities with the inhabitants. They then commenced their operations with measuring a piece of ground, which was to be the base of the whole work, and in this the remainder of the year 1736 was consumed. The plain of Yaruqui, selected for this purpose, is situated one thousand four hundred and ninety-four feet lower than Quito, and is four leagues to the north-east of that city. “The quality, disposition, and lower situation, all contribute to render it less cold than Quito. Eastward it is defended by the lofty cordillera of Guamani and Pambamarca, and westward by that of Pichincha. The soil is entirely sand; so that besides the heat naturally resulting from the direct rays of the sun, it is increased by the rays being reverberated by the two cordilleras: hence it is also exposed to violent tempests of thunder, lightning, and rain. But being quite open towards the north and south, such dreadful whirlwinds form here that the whole interval is filled with columns of sand, carried up by the rapidity and gyrations of violent eddy winds, which sometimes produce fatal consequences; one melancholy instance happened while we were there—an Indian, being caught in one of these blasts, died on the spot. It is not indeed at all strange that the quantity of sand in one of these columns should totally stop all respiration in any living creature who has the misfortune of being involved in it.”

The daily labour of the whole party was measuring the length of this plain in a horizontal direction, while the inequalities of the ground were at the same time corrected by means of a level. They commenced their task early in the morning, and, unless when interrupted by bad weather, or the too intense heat of the sun at noon, continued actively employed until the evening. The plain of Cazambe had first been made choice of; but after a short trial, during which M. Couplet, one of the French academicians, died suddenly, this position was abandoned. It was now determined, therefore, to continue the series of triangles to the south of Quito, and the whole company dividing itself into two parties, the one to which Don George Juan was attached proceeded to the mountain of Pambamarca, while Ulloa, La Condamine, and Bouguer climbed up to the highest summit of Pichincha. “Our first scheme,” says Ulloa, “for shelter and lodging in these uncomfortable regions, was to pitch a field-tent for each company; but on Pichincha this could not be done, from the narrowness of the summit, and we were obliged to be contented with a hut, so small that we could hardly all creep into it. Nor will this appear strange if the reader considers the bad disposition and smallness of the place, it being one of the loftiest crags of a rocky mountain, one hundred toises above the highest part of the desert of Pichincha. Such was the situation of our mansion, which, like all the other adjacent parts, soon became covered with ice and snow. The ascent up this stupendous rock, from the base, or the place where the mules could come to our habitation, was so craggy as only to be climbed on foot, and to perform it cost us four hours’ continual labour and pain, from the violent efforts of the body, and the subtilty of the air—the latter being such as to render respiration difficult. It was my misfortune, when I climbed something above half-way, to be so overcome that I fell down, and remained a long time without sense or motion, and, I was told, with all the appearances of death in my face. Nor was I able to proceed after coming to myself, but was obliged to return to the foot of the rock, where our servants and instruments remained. The next day I renewed the attempt of climbing the rock, though probably I should have had no better success than before, had not some Indians assisted me in the most steep and difficult places.”

The picture which Ulloa has given of their extraordinary manner of living would lose so much of its interest by being transferred into any other language than his own, that I cannot resist the temptation to continue the narrative in his words: “We generally kept within one hut,” says he; “indeed, we were obliged to do this, both on account of the intenseness of the cold, the violence of the wind, and our being continually involved in so thick a fog that an object at six or eight paces was hardly discernible. When the fog cleared up, the clouds, by their gravity, moved nearer to the surface of the earth, and on all sides surrounded the mountain to a vast distance; representing the sea, with our rock like an island in the centre of it. When this happened, we heard the horrid noises of the tempests, which then discharged themselves on Quito and the neighbouring country. We saw the lightning issue from the clouds, and heard the thunders roll far beneath us; and while the lower parts were involved in tempests of thunder and rain, we enjoyed a delightful serenity; the wind was abated, the sky clear, and the enlivening rays of the sun moderated the severity of the cold. But our circumstances were very different when the clouds arose; their thickness rendered respiration difficult; the snow and hail fell continually; and the wind returned with all its violence; so that it was impossible entirely to overcome the fears of being, together with our hut, blown down the precipice on whose edge it was built, or of being buried under it by the daily accumulation of ice and snow.

“The wind was often so violent in these regions, that its velocity dazzled the sight, while our fears were increased by the dreadful concussions of the precipice, and by the fall of enormous fragments of rocks. These crashes were the more alarming, as no other noises are heard in these deserts; and during the night our rest, which we so greatly wanted, was frequently disturbed by such sudden sounds. When the weather was any thing fair with us, and the clouds gathered about some of the other mountains which had a connexion with our observations, so that we could not make all the use we desired of this interval of good weather, we left our huts to exercise ourselves, in order to keep us warm. Sometimes we descended to some small distance; and at other times amused ourselves with rolling large fragments of rocks down the precipices, and these many times required the joint strength of us all, though we oftentimes saw the same performed by the mere force of the wind. But we always took care in our excursions not to go so far but that, on the least appearance of the clouds gathering about our cottage, which often happened very suddenly, we could regain our shelter. The door of our hut was fastened with thongs of leather, and on the inside not the smallest crevice was left unstopped; besides which it was very compactly covered with straw. But notwithstanding all our care, the wind penetrated through. The days were often little better than the nights, and all the light we enjoyed was that of a lamp or two, which we kept burning that we might distinguish one another, and improve our time as much as possible in reading. Though our hut was small and crowded with inhabitants, besides the heat of the lamps, yet the intenseness of the cold was such, that every one of us was obliged to have a chafing-dish of coals. These precautions would have rendered the rigour of the climate supportable, had not the imminent danger of perishing by being blown down the precipices roused us, every time it snowed, to encounter the severity of the outward air, and sally out with shovels to free the roof of the hut from the masses of snow that were gathering on it. Nor would it, without this precaution, have been able to support the weight. We were not indeed without servants and Indians, but they were so benumbed with cold, that it was with great difficulty we could get them out of a small tent, where they kept a continual fire; so that all we could obtain from them was to take their turns in this labour,—and even then they went very unwillingly about it, and consequently performed it slowly.

“It may easily be conceived what we suffered from the asperity of such a climate. Our feet were swelled, and so tender that we could not even bear the heat, and walking was attended with great pain. Our hands were covered with chilblains, our lips swelled and chopped, so that every motion, speaking and the like, drew blood; consequently we were obliged to observe a strict taciturnity, and were but little disposed to laugh—an extension of the lips producing fissures, very painful for two or three days together.

“Our common food in this inhospitable region was a little boiled rice, with some flesh or fowl, which we procured from Quito; and instead of fluid water, our pot was filled with ice; we had the same resource with regard to what we drank; and while we were eating every one was obliged to keep his plate over a chafing-dish of coals, to prevent his provisions from freezing. The same was done with regard to the water. At first we imagined that drinking strong liquors would diffuse a heat through the body, and consequently render it less sensible of the painful sharpness of the cold; but, to our surprise, we found no manner of strength in them, nor were they any greater preservative against the cold than common water. For this reason, together with the apprehension that they might prove detrimental to our health, besides the danger of contracting an ill habit, we discontinued their use; having recourse to them but very seldom, and then sparingly. We frequently gave a small quantity to our Indians, together with part of the provisions which were continually sent us from Quito, besides a daily salary four times as much as they usually earn.
