Wall and Sawkins saw with their own eyes, in 1856, about two miles from this Cedros Salse, the results of an explosion which had happened only two months before, and of which they give a drawing.

A surface two hundred feet round had been upheaved fifteen feet, throwing the trees in every direction; and the sham earthquake had shaken the ground for two hundred or three hundred yards round, till the natives fancied that their huts were going to fall.
There is a third Salse near Poole River, on the Upper Ortoire, which is extinct, or at least quiescent; but this, also, I could not visit.

It is about seventeen miles from the sea, and about two hundred feet above it.

As for the causes of these Salses, I fear the reader must be content, for the present, with a somewhat muddy explanation of the muddy mystery.
