SIBERIA. To the love of science which the enlightened Emperor of Russia, has always manifested, we are indebted for an expedition, the most successful which has yet been undertaken for the exploration of the northern and eastern parts of Siberia. The results of this extensive exploration of a region not before examined by scientific men, are of the greatest interest to science, and have earned for its distinguished and undaunted leader, Prof. Von Middendorff, the applause of the savans of Europe. Not having seen any detailed account of this journey, I am indebted to Sir R. Murchison for some particulars of its results.[94] The expedition traversed the whole extent of Siberia, from east to west, and from south to north, even to the extreme northern headland of Taimyr. "Undaunted by the severe privations he had undergone in obtaining his knowledge of the far northern lands of Siberia, he next undertook the not less arduous task of traversing the whole of that vast continent to the Shantar Isles, at its southeastern extremity, and thence to return to Nertchinsk, along the Chinese frontier. His journey through thickly-wooded rocks, deep morasses and over swollen rivers, was so successfully accomplished, that the stores he has brought back to St. Petersburgh, will fully lay open the Fauna and Flora of a region never previously explored by a man of science." "Floating down the sea of Okotsk from Udskoi in frail canoes, M. Middendorff and his friends, braving shoals of floating ice and perpetual rains, reached Nitka on the great Shantar island. The wild regions which were traversed, in many parts could only be threaded by _following the tracks formed by bears beneath the dense matting of underwood and birch trees_" In his return journey, he examined the frontier line of China, a tract never explored even by a Cossack, and ascertained that between the Udskoi of the Russians and the mouth of the Amur, there is a considerable tract quite independent both of Russia and China, and occupied by a people called Guilaiques, who pay no tribute to either Emperor.
