of considerable importance,but it now merely sends forth puffs of steam from asmall orifice at the top. Near it is a quiet hot-spring with a most elegantly scalloped rim. Backof this Pyramid is the Punch Bowl, and still furthersouth, the Black Sand Geyser, neither of whichhas been specially described. Eeturning to the river and crossing we find at thewaters edge, nearly opposite the Grotto, the Kiver-side Geyser, and a short distance below, on thesame side, is the Fan. The latter geyser has adouble orifice, which discharges five radiating jetsto the height of sixty feet, the falling drops andspray giving the appearance of a feather fan. Theeffect is very beautiful. Its eruptions are frequent,lasting usually from ten to thirty minutes. A ventconnected with it, about forty feet distant, expelsdense masses of vapor fifty or sixty feet high, ac-companied by loud, sharp reports, during the timethe geyser is in action. Lieutenant Doane describesthe curious action of these vents as follows :

UPPER GEYSER BASIK I59 First the steam would rush from the upper cra-ter, roaring violently, then this would suddenlycease, to be followed by a fan-like jet of water risingfrom the lower crater to the height of over fortyfeet, playing for perhaps two minutes; then thiswould suddenly stop flowing, and the steam wouldrush forth again for a time. Occasionally the smallcrater threw a transverse stream, alternating withthe others; and thus they played on for hours, afterwhich all would subside to a gentle bubbling. Along both banks of the river are small cratersbuilt up in every conceivable shape. Severalstreams pour out cascades from round holes inthe rocky bank of the river, and all around are littlegeysers playing at intervals from six to forty feet. A plateau opposite the Fan contains fifteen hotsprings of various characteristics ; some are of adeep blue color and have fantastic caverns distinctlyvisible below the surface of the water. The open-ings at the surface are often beautifully
