About 365 versts below Turuchansk is situated Plachina, the fishing-station of a small tribe of Samoïedes, among whom Castrén tarried three weeks. He had taken possession of the _best_ of the three huts of which the place consisted, but even this would have been perfectly intolerable to any one but our zealous ethnologist. Into his study the daylight penetrated so sparingly through a small hole in the wall, that he was often obliged to write by the light of a resinous torch in the middle of the day. The flame flickering in the wind, which blew through a thousand crevices, affected his eyes no less severely than the smoke, which at the same time rendered respiration difficult. Although the roof had been repaired, yet during every strong rain--and it rained almost perpetually--he was obliged to pack up his papers, and to protect himself from the wet as if he had been in the open air. From this delightful residence, Castrén, still pursuing his study of the Samoïede dialects, proceeded down the river to Dudinka, and finally, in November, to Tolstoi Noss, whose pleasant climate may be judged of by the fact that it is situated in the latitude of 71°. This last voyage was performed in a “balok,” or close sledge, covered with reindeer skins. The tediousness of being conveyed like a corpse in a dark and narrow box, induced him to exchange the “balok” for an open sledge; but the freezing of his feet, of his fingers, and of part of his face, soon caused him to repent of his temerity. As soon as this accident was discovered at the next station, Castrén crept back again into his prison, and was heartily glad when, after a nine days’ confinement, he at length arrived at Tolstoi Noss, which he found to consist of four wretched huts. Here again he spent several weeks studying by torchlight, for the sun had made his last appearance in November, and the day was reduced to a faint glimmering at noon. In January we find him on his return-voyage to Turuchansk, a place which, though not very charming in itself, appeared delightful to Castrén after a six months’ residence in the tundras beyond the Arctic Circle.
