"It is the dew, Chanito; it is almost as abundant as the night dews in the Terre-Chaude."

"Are not morning and night dews the same thing?"

"Not exactly," I replied; "the morning dew is generally of a beneficial nature; but the Mexicans dread the other, which falls after sunset, and is said to be productive of fever."

"But from whence does all this moisture come?"

"From the air, which always contains a certain quantity, some of which it deposits on the ground, on stones and plants, as they become cool by radiation."

Just at this moment our attention was attracted by the first ray of the sun, which, piercing through a light cloud, shot across the plain like a bright arrow. The horizon, which had been visible, was now obscured by a mist, which gradually rolled towards us. By degrees, however, it drew off, and the trees a short distance away showed their rounded tops; while wide breaks opened here and there in the semi-transparent veil, and vanished as quickly as they had arisen.

The telescope was passed from hand to hand, and each tried to discover if there was a hut where the glimmering fire had been descried the night before. The search was in vain; the reflection of the sun's rays quite dazzled us, and restricted the prospect; but, once in the right course, we might advance without fear of missing our point, and, according to our calculations, we would meet with habitations the next day or the following.

Gringalet's tongue hung out of his mouth; he found the journey over the nitrous soil very irksome, and the scanty leaves of the mimosa failed to screen him from the sun. What a contrast it was to the pleasant regions we had hitherto travelled through!

"Your country, after all, is not so nice a one as mine," said Lucien, addressing l'Encuerado.

"My real native country is much more beautiful than that we are now in, Chanito; in the first place, it has mountains and woods, and there it sometimes rains."
