A hundred yards distant from The Giantess \Yas a siliceous coue, very symmetrical but slightly corrugated upon its exterior surface, 3 feet in height and 5 feet in diameter at its base, and having an oval orifice 24 9. by 36J inches in diameter, with scalloped edges. Xot one of our company supposed that it was a ge^'serj and among so many wonders it had almost escaped notice. While we were at breakfast u^dou the morning of our departure a Col- umn of water, entirely filling the crater, shot from it, which, by accurate triangular meas- il urement, we found to be 219 feet in height. The stream did not deflect more than four or five degrees from a vertical line, and the eruption lasted eighteen minutes. We named it'' The ; (Fig. 60.) The illustration of the Gi- antess in action, for the use of which in this report, I am indebted to the liberality of the editors of Scribner^s Monthly, shows most admirably the suc- cession of impulses by which the column of water is held up, apparently so steadily for so long a time. We did not see this wonderful geyser in operation during our visit; but it has been so graphically described by Mr. Langford, and so faith- fully depicted by Mr. Moran, the artist, that little more need be added. The Fan Geyser consists of a group of five geysers, which play at one time, throwing the water in every direction. There is one quite conspicuous cone, marked on the chart. Pyramid, which is now extinct, except that from the summit steam is constautl}^ escaping. This has been a geyser of some importance, and has built up a structure 25 feet high, and 100 feet in diameter at the base. Near it is a quiet spring with a most elegantly scalloped rim. the careful study of a month under the most favora- to obtain full and clear information in regard to all. THE GIANTESS.
