La Perouse had some intercourse with the natives of Crillon Cape, and stated that they were handsome men, far more industrious than the Orotchys of Casters Bay, but less liberal in their dealings. "They have," he says, "one most important article of commerce--unknown in the channel of Tartary--from which they derive their riches, namely, whale oil. Of this they collect considerable quantities. They extract it in a way which is far from economical. They cut the flesh into pieces, and dry it upon a slope in the open air, by exposing it to the sun. The oil which flows from it is caught in vessels made of bark, or into bottles of dried sealskin." After sighting the Cape Arniva of the Dutch, the vessels coasted along the barren, treeless, uninhabited country in possession of the Dutch Company, and shortly reached the Kurile Islands. They then passed between Marikon Island and the Island of the Four Brothers, calling the strait--the finest amongst the Kurile Islands, through which they penetrated--La Boudeuse. On the 3rd of September the coast of Kamtchatka was reached. This coast was uninviting enough. "There the eyes rest painfully, and often fearfully, upon enormous masses of rock, which are already covered with snow in the beginning of September, and which never appear to have had any vegetation." Three days later Avatscha Bay, or the Bay of Saint Peter and Saint Paul, was reached. The astronomers at once proceeded to take observations; the naturalists made the perilous and arduous ascent of a volcano, some eight leagues inland; whilst those of the crew who were not engaged upon the vessels gave themselves up to hunting and fishing. Thanks to the welcome accorded by the governor, their pleasures were varied.
