The Geology of this part of Tierra del Fuego was, as indeed every place is, to me very interesting. The country is non-fossiliferous, and a common- place succession of granitic rocks and slates; attempting to make out the relation of cleavage, strata, etc., etc., was my chief amusement. The mineralogy, however, of some of the rocks will, I think, be curious from their resemblance to those of volcanic origin.英文原著 · 《The Life and Letters-1》
