But at length, in the month of December, the observations on Pichincha were completed, and they proceeded to other points, where the same fatigues and privations were encountered. Only the hut was now exchanged for a field-tent, which, although in some respects more troublesome, was less inconvenient than their Pichincha hut. Nevertheless, as the tents were necessarily placed in exposed situations to serve as signals, they were frequently overthrown by the violence of the wind, which rose in those wild paramos to a pitch altogether indescribable.

But by degrees their bodies became inured to the hardships which they endured.
