At least the direction of the rivers appears to havebeen unchanged since then. Perhaps even the differencebetween the Siberia where Chikanovskis Ginko woods grewand the mammoth roamed about, and that where now at alimited depth under the surface constantly frozen ground is tobe met with, depends merely on the isothermal lines havingsunk slightly towards the equator.

In the middle of the severe cold of February its watershad a temperature of + 69° C. Hot steam and drifting snowcombined had thrown over the spring a lofty vault of dazzlingwhiteness formed of masses of snow converted into ice andcovered with ice-crystals. The Chukches themselves appearto have found the contrast striking between the hot springfrom the interior of the earth and the cold, snow, and ice on itssurface. They offered blue glass beads to the spring, andshowed Hooper, as something remarkable, that it was possibleto boil fish in it, though the mineral water gave the boiled fisha bitter unpleasant taste.^ The interi
