The mushroom-like algous growthsseen in some of the bordering pools are of interest to thescientist who knows what an important part the algae havein the rate and manner of deposition of silica, and on ac-count of their peculiar forms and colors. The Oblong Geyser is on the opposite side of theFirehole Eiver from Chromatic Pool. Its crater is re-markable in that no better example of interior geyserstructure is seen in the entire park. Large globular massesof tan colored geyserite form the rim; the water is a deli-cate blue color and of such transparency that the twofissures in the bottom of the crater are plainly seen.

GEOLOGICAL.—^A geyser may be defined as aperiodically erupting hot spring, its water is not volcanicbut simply hot meteoric water; so a geyser is not a volcanoejecting water but a true spring. Were the heat suflBcientand the tube long enough all hot springs would erupt. Sounds like cannonading are heard directly preced-ing a geyser eruption; this is caused by the collapse ofsteam bubbles from the hot region below rising throughthe cooler strata of water. The surface of the pool, fromwhich the geyser plays, bulges and overflows, and some-times jets of water are thrown upward preceding activity. The famous scientist, E. W. Bunsen, after making acareful study of geyser action by extensive observationand experiment, advanced the following authoritative ex-planation : It is well known th
