The union of a cloudless sky, low temperature, and a furious gale of wind, must be, I should think, in all parts of the world an unusual occurrence.
JUNE 29, 1835.
We gladly travelled down the valley to our former night's lodging, and thence to near the Agua amarga.

On July 1st we reached the valley of Copiapo.

The smell of the fresh clover was quite delightful, after the scentless air of the dry sterile Despoblado.
Whilst staying in the town I heard an account from several of the inhabitants, of a hill in the neighbourhood which they called "El Bramador,"-- the roarer or bellower.

I did not at the time pay sufficient attention to the account; but, as far as I understood, the hill was covered by sand, and the noise was produced only when people, by ascending it, put the sand in motion.

The same circumstances are described in detail on the authority of Seetzen and Ehrenberg, as the cause of the sounds which have been heard by many travellers on Mount Sinai near the Red Sea.
