Contributions in geographical exploration . up by theshifting ash and sand. Xo. 44. T. 100° C. Mud Volcanoes, first area. IX. \ 13 W Ml. Magcik, S 31 E. X, S 23 W. From a distance this appeared as a gentle area of steamers. It was not until we had approached the center of the area, waist dtx-j) in steam. blown close to the ground by the wind, that we realised it was difTcR-iU. 276 The Ohio Jonnial of Science [Vol. XIX, No. 5, Globules of blue mud shot into the air with a pop and fell back intoits basin with a splash, only to be followed by many similar outbreaksall around us. Going to windward we saw the seat of the ground was covered with boiling blue mud pots, some with aconsistency of well cooked mush, while in others the boiling water wasalmost clear. It was to secure satisfactory pictures of theperfomiance, because of the thick blanket of rising steam that coveredan area of an acre or more. The mud was blue black. The temperaturewas that of steam, 100° C. Photographs 4146, 4151, 4152, 4558, 45( Photograph by Paul R. Hagelbarger PLACING THE THERMOCOUPLE IN FUMAROLE 33. This inconspicuous crack, with the thermocouple placed as in the picture, gave a temperature of 432° C, the highest measured in the valley. The ground near the fissure was too hot to stand on very long, so we supported the cold junction of the thermocouple on a spade. No. 45. T. 412°C. IX, N low. X, S 19 W. Mt. Mageik, S 35 E. Between No. 33 and No. 36 and the east bank of the canyon fromKnife Peak Valley was a conspicuous steamer. As we approached it,200 yards to the eastward, we came upon the end of the fissure whichgave forth a big column of steam where it was crossed by the deposits here were light colored. At different places in the smallcracks in the roof of the fissure the temperatures were 289° C., 318° C,387° C., 412° C., 402° C., 397° C. The main steamer, we found,had a temperature of 360° C. at the surface of the ground. No. 46. T. 171°
