Late in June, however, Colonel Bulkley learned that a small Russian trading-vessel named the _Olga_ was about to sail from San Francisco for Kamchatka (kam-chat'-kah) and the south-western coast of the Okhotsk Sea, and he succeeded in prevailing upon the owners to take four men as passengers to the Russian settlement of Nikolaievsk (nik-o-lai'-evsk), at the mouth of the Amur River. This, although not so desirable a point for beginning operations as some others on the northern coast of the Sea, was still much better than any which could be selected on the Asiatic coast of the North Pacific; and a party was soon organised to sail in the _Olga_ for Kamchatka and the mouth of the Amur. This party consisted of Major S. Abaza, a Russian gentleman who had been appointed superintendent of the work, and leader of the forces in Siberia; James A. Mahood, a civil engineer of reputation in California; R. J. Bush, who had just returned from three years' active service in the Carolinas, and myself,--not a very formidable force in point of numbers, nor a very remarkable one in point of experience, but strong in hope, self-reliance, and enthusiasm. On the 28th of June, we were notified that the brig _Olga_ had nearly all her cargo aboard, and would have "immediate despatch." This marine metaphor, as we afterward learned, meant only that she would sail some time in the course of the summer; but we, in our trustful inexperience, supposed that the brig must be all ready to cast off her moorings, and the announcement threw us into all the excitement and confusion of hasty preparation for a start. Dress-coats, linen shirts, and fine boots were recklessly thrown or given away; blankets, heavy shoes, and overshirts of flannel were purchased in large quantities; rifles, revolvers, and bowie-knives of formidable dimensions gave our room the appearance of a disorganised arsenal; pots of arsenic, jars of alcohol, butterfly-nets, snake-bags, pill-boxes, and a dozen other implements and appliances of science about which we knew nothing, were given to us by our enthusiastic naturalists and packed away in big boxes; Wrangell's (vrang'el's) _Travels_, Gray's _Botany_, and a few scientific works were added to our small library; and before night we were able to report ourselves ready--armed and equipped for any adventure, from the capture of a new species of bug, to the conquest of Kamchatka!
