[Illustration: “_* * * and behold! The whole country beyond was

smoking with vapor from boiling springs, and burning with gases

issuing from small craters, each of which was emitting a sharp,

whistling sound. * * * The general face of the country was smooth

and rolling, being a level plain, dotted with cone-shaped mounds. On

the summit of these mounds were small craters from four to six feet

in diameter. Interspersed among these on the level plain were larger

craters, some of them four to six miles across. Out of these

craters, issued blue flames and molten brimstone._”
