THREE STAGES OF THE ERUPTION AT SAN SALVADOR VOLCANO 'tahe last remnant of the lake has disappeared completely. In its place a gate to Pluto's world hadformed and initscenter blazes afiery foun tain It seems incredible that clouds of such volume filled with gigantic stones and lava could shootfrom comparatively sosmall anopening. They bound forth with such tremendous force, such terrific thundering crashes, that the crater wallstremble asviolently astheearth. The air pressure is so strong that we are thrown off our feet. A smoke column rises about Ioo yards high inthe air,followed byanexplosion compared with which that of the n2cm. guns would seem like that of a toy. The crater itself is like the sounding board ofaphonograph and thecrater walls repeat the detonation twenty times and more. It sounds for all the world like a continuous bombardment. The gases make their escape with hissing and whizzing and evaporate in long bluish flames."-Note from Mrs. Martha Toeplitz.
