The beach here is formed of a low bank of sand which runs between the sea and a small shallow lagoon or fresh-water lake, whose surface is nearly on a level with that of the sea. Farther into the interior the land rises gradually to bare hills, clear of snow or only covered with a thin coating of powdered snow from the fall of the last few days. Lagoon formations, with either fresh or salt water, of the same kind as those which we saw here for the first time, are distinctive of the north-eastern coast of Siberia. It is these formations which gave rise to the statement that on the north coast of Siberia it is difficult to settle the boundaries between sea and land. In winter this may be difficult enough, for the low bank which separates the lagoon from the sea is not easily distinguished when it has become covered with snow, and it may therefore readily happen in winter journeys along the coast that one is far into the land while he still believes himself to be out on the sea-ice. But when the snow has melted, the boundary is sharp enough, and the sea by no means shallow for such a distance as old accounts would indicate. A continual ice-mud-work also goes on here during the whole summer. Quite close to the beach accordingly the depth of water is two metres, and a kilometre farther out ten to eleven metres. Off the high rocky promontories the water is commonly navigable even for vessels of considerable draught close to the foot of the cliffs. The villages of the Chukches commonly stand on the bank of sand which separates the lagoon from the sea. The dwellings consist of roomy skin tents, which enclose a sleeping chamber of the form of a parallelepiped surrounded by warm well-prepared reindeer skins, and lighted and warmed by one or more train-oil lamps. It is here that the family sleep during summer, and here most of them live day and night during winter. In summer, less frequently in winter, a fire is lighted besides in the outer tent with wood, for which purpose a hole is opened in the top of the raised tent-roof. But to be compelled to use wood for heating the inner tent the Chukches consider the extremity of scarcity of fuel. [Illustration: CHUKCH TENT. (After a photograph by L. Palander.) ]
