We left the city by the gate of Guadalupe, and passed by the great cathedral, our road lying over the marshy plains once covered by the waters of Lake Tezcuco.

To the east lay the great lake, its broad waters shining like a sheet of molten silver, and the two great volcanoes: the rising sun forming a crown of rays on the white brow of Popocatepetl.

To describe once for all the general aspect of the country on this side of the valley of Mexico, suffice it to say, that there is a universal air of dreariness, vastiness, and desolation. The country is flat, but always enlivened by the surrounding mountains, like an uninteresting painting in a diamond frame; and yet it is not wholly uninteresting. It has a character peculiar to itself, great plains of maguey, with its huts with uncultivated patches, that have once been gardens, still filled with flowers and choked with weeds; the huts themselves, generally of mud, yet not unfrequently of solid stone, roofless and windowless, with traces of having been fine buildings in former days; the complete solitude, unbroken except by the passing Indian, certainly as much in a state of savage nature as the lower class of Mexicans were when Cortes first traversed these plains—with the same character, gentle and cowardly, false and cunning, as weak animals are apt to be by nature, and indolent and improvident as men are in a fine climate; ruins everywhere—here a viceroy's country palace serving as a tavern, where the mules stop to rest, and the drivers to drink pulque— there, a whole village crumbling to pieces; roofless houses, broken down walls and arches, an old church—the remains of a convent…. For leagues scarcely a tree to be seen; then a clump of the graceful Arbol de Peru, or one great cypress—long strings of mules and asses, with their drivers— pasture-fields with cattle—then again whole tracts of maguey, as far as the eye can reach; no roads worthy of the name, but a passage made between fields of maguey, bordered by crumbling-down low stone walls, causing a jolting from which not even the easy movement of Charles X's coach can save us. But the horses go at full gallop, accustomed to go through and over everything.

The first village we saw was Santa Clara, to our left, lying at the foot of some dark hills, with its white church and flat-roofed or no-roofed houses. There being no shade, frequently not a tree for leagues, the sun and dust very disagreeable, and became more so as the day advanced. Here it came to pass, that, travelling rapidly over the hot and dusty plains, the wheels of our carriage began to smoke. No house was in sight—no water within ken. It was a case of difficulty; when suddenly ——- recollected that not far from thence was an old rancho, a deserted farmhouse at present occupied by robbers; and having ordered the coachman to drive to within a few hundred yards of this house, he sent a servant on horse- back with a medio (fourpence) to bring some water, which was treating the robbers like honourable men. The man galloped off, and shortly returned with a can full of water, which he carried back when the fire was extinguished.

Meanwhile we examined, as well as we could, the external appearance of the robbers' domicile, which was an old half-ruined house, standing alone on the plain, with no tree near it. Several men, with guns, were walking up and down before the house—sporting-looking characters, but rather dirty—apparently either waiting for some expected game, or going in search of it. Women with rebosos, were carrying water, and walking amongst them. There were also a number of dogs. The well-armed men who accompanied us, and the name of ——-, so well known in these parts, that once when his carriage was surrounded by robbers, he merely mentioned who he was, and they retreated with many apologies for their mistake, precluded all danger of an attack; but woe to the solitary horseman or the escorted carriage that should pass thereby! Nor, indeed, are they always in the same mood, for Señor ——-'s houses have been frequently attacked in his absence, and his hacienda at Santiago once stood a regular siege, the robbers being at length repulsed by the bravery of his servants.

We set off again au grand galop, drivers and outriders giving, from time to time, the most extraordinary shrieks to encourage the horses and to amuse themselves, wild and shrill enough to frighten any civilized quadruped. The road grew more picturesque as we advanced, and at length our attention was arrested by the sight of the two great pyramids, which rise to the east of the town of San Juan Teotihuacan, which are mentioned by Humboldt, and have excited the curiosity and attention of every succeeding traveller. The huge masses were consecrated to the sun and moon, which, in the time of Cortes, were there represented by two vast stone idols, covered with gold. The conquerors made use of the gold, and broke the idols in pieces, by order of the first bishop of Mexico. Unfortunately, our time was too limited to give them more than a passing observation. Fragments of obsidian, in the form of knives and of arrows, with which the priests opened the breasts of their human victims, are still to be found there; and numerous small idols, made of baked clay, are to be seen both there and in the plains adjoining. The Indians rather dislike to guide travellers to these pyramids, and their reluctance to do so has increased the popular belief of the existence of great concealed treasures near or in them.

The whole plain on which these great pyramids stand was formerly called Micoatl, or the Pathway of the Dead; and the hundreds of smaller pyramids which surround the larger ones (the Temples of the Sun and Moon) are symmetrically disposed in wide streets, forming a great burial-plain, composed perhaps of the dust of their ancient warriors, an Aztec or Toltec Pere-la-Chaise, or rather a roofless Westminster Abbey. So few of the ancient teocallis now remain, and these being nearly the only traces now existing of that extraordinary race, we regretted the more not being able to devote some time to their examination. Fanaticism and policy induced the Spanish conquerors to destroy these heathen temples; and when we recollect that at the time of the Reformation in civilized England, the most splendid Catholic edifices were made level with the ground, in compliance with the ferocious edict of John Knox, "Ding down the nests, and the rooks will fly off," we can have little wonder or blame to bestow upon Cortes, who, in the excitement of the siege, gave orders for the destruction of these blood- stained sanctuaries. In the afternoon we arrived at San Juan, a pretty village, boasting of an inn, a school-house, an avenue of fine trees, and a stream of clear water. It is true that the inn is a Mexican posada, bearing as much resemblance to what is generally called an inn, as an hacienda does to an English country-house; the school-house, a room with a mud floor and a few dirty benches, occupied by little ragged boys and girls; but the avenue is pretty, the grass as green as emeralds, and the water crystal. We walked out while they changed horses, of which Señor ——- had fresh relays of his own prepared all along the road; and entered the school-house, attracted by the noise and the invitingly open door. The master was a poor, ragged, pale, careworn looking young man, seemingly half-dinned with the noise, but very earnest in his work. The children, all speaking at once, were learning to spell out of some old bills of Congress. Several moral sentences were written on the wall in very independent orthography. C—-n having remarked to the master that they were ill-spelt, he seemed very much astonished, and even inclined to doubt the fact. I thought it was one of those cases where ignorance is bliss, and fear the observation may have cost the young man a night's rest.

A row of grinning skulls was ranged round the wall of the churchyard, and the sexton, who gave us admittance to the church, taking up one to show it off, it all crumbled into dust, which filled the air like a cloud.

At the posada they gave us rancid sheep's milk, cheese, and biscuits so hard, that C—-n asked the host if they were made in the same year with the church; at which he seemed mightily pleased, and could not stop laughing till we got into the carriage.

Soon after leaving San Juan we were met by the Señora de ——-, in an open carriage, coming with her children to meet us; and though she had travelled since sunrise from her hacienda, she appeared as if freshly dressed for an evening party; her dress, amber-coloured crape, trimmed with white blonde, short sleeves and decolletee; a set of beautiful Neapolitan strawberry- coral, set in gold, straw-coloured satin shoes, and a little China crape shawl, embroidered in bright flowers; her hair dressed and uncovered.
