From the summit the stream is continually arising from a number of vents, each one of which is lined with sulphur. Quantities of steam are ever ascending from the springs, but on a damp morning the entire slope of the mountain is enveloped in clouds of vapor. The question of the an- Fig. 19. tiquityof these springs is one of great interest, and yet, with all the evidence before us, it is somewhat obscure. Upon the mar-- gins of tlie mountain, high above the present position of the hot sx)rings, is a bed of very Avhite or yeliowish- white limestone, 50 to 150 ^S feet thick, and appearing - "^ in the distance like very pure Carboniferous lime- stone. (Fig. 20.) It is reg- ularly stratified, and the jointing is complete, and immense masses have fallen down on the slope of the mountain side. There is a belt a mile long and one-fourth, of a mile wide, covered with ,. SirgS^, - ,„.
