Here and there were traces of lava.

Sulphur springs sometimes stopped their way, and they had to go round them.

In some places the sulphur had formed crystals among other substances, such as whitish cinders made of an infinity of little feldspar crystals.
In approaching the first plateau formed by the truncating of the lower cone, the difficulties of the ascent were very great.

Towards four o'clock the extreme zone of the trees had been passed.

There only remained here and there a few twisted, stunted pines, which must have had a hard life in resisting at this altitude the high winds from the open sea.
