The large island right opposite to Svjatoinos was discovered in 1770 by LJACHOFF, whose name the island now bears. In 1788 Billings' private secretary, MARTIN SAUER, met with Ljachoff at Yakutsk, but he was then old and infirm, on which account, when Sauer requested information regarding the islands in the Polar Sea, he referred him to one of his companions, ZAITAI PROTODIAKONOFF. He informed him that the discovery was occasioned by an enormous herd of reindeer which Ljachoff, in the month of April 1770, saw going from Svjatoinos towards the south, and whose track came over the ice from the north. On the correct supposition that the reindeer came from some land lying to the north, Ljachoff followed the track in a dog-sledge, and thus discovered the two most southerly of the New Siberian Islands, a discovery which was rewarded by the Czarina Catherine II. with the exclusive right to hunt and collect ivory on them.[234] [Illustration: LJACHOFF'S ISLAND. After a drawing by O. Nordquist. ] Ljachoff states the breadth of the sound between the mainland and the nearest large island at 70 versts or 40'. On Wrangel's map again the breadth is not quite 30'. On the mainland side it is bounded by a rocky headland projecting far into the sea, which often formed the turning point in attempts to penetrate eastwards from the mouth of the river Lena, and perhaps just on that account, like many other headlands dangerous to the navigator on the north coast of Russia, was called _Svjatoinos_ (the holy cape), a name which for the oldest Russian Polar Sea navigators appears to have had the same signification as "the cape that can be passed with difficulty." No one however now thinks with any apprehension of the two "holy capes," which in former times limited the voyages of the Russians and Fins living on the White Sea to the east and west, and this, I am quite convinced, will some time be the case with this and all other holy capes in the Siberian Polar Sea. The sea water in the sound was much mixed with river water and had a comparatively high temperature, even at a depth of nine to eleven metres. The animal life at the sea bottom was poor in species but rich in individuals, consisting principally of _Idothea entomon_, of which Dr. Stuxberg counted 800 specimens from a single sweep of the dredge. There were obtained at the same time, besides a few specimens of _Idothea Sabinei_, sponges and bryozoa in great abundance, and small mussels, crustacea, vermes, &c. Various fishes were also caught, and some small algae collected. The trawl-net besides brought up from the bottom some fragments of mammoth tusks, and a large number of pieces of wood, for the most part sticks or branches, which appear to have stood upright in the clay, to judge from the fact that one of their ends was often covered with living bryozoa. These sticks often caused great inconvenience to the dredgers, by tearing the net that was being dragged along the bottom.
