Similar investigations have since been made, among others, by M. TISSANDIER in Paris, and during NARES' English Polar Expedition.
It may appear to many that it is below the dignity of science to concern one's self with so trifling an affair as the fall of a small quantity of dust. But this is by no means the case. For I estimate the quantity of the dust that was found on the ice north of Spitzbergen at from 0.1 to 1 milligram per square metre, and probably the whole fall of dust for the year far exceeded the latter figure. But a milligram on every square metre of the surface of the earth amounts for the whole globe to five hundred million kilograms (say half a million tons)! Such a mass collected year by year during the geological ages, of a duration probably incomprehensible by us, forms too important a factor to be neglected, when the fundamental facts of the geological history of our planet are enumerated. A continuation of these investigations will perhaps show, that our globe has increased gradually from a small beginning to the dimensions it now possesses; that a considerable quantity of the constituents of our sedimentary strata, especially of those that have been deposited in the open sea far from land, are of cosmic origin; and will throw an unexpected light on the origin of the fire-hearths of the volcanoes, and afford a simple explanation of the remarkable resemblance which unmistakably exists between plutonic rocks and meteoric stones.[192]
On the 14th August, when the fog had lightened a little, we got up steam, but were soon compelled to anchor again in a bay running into Taimur Island from the north side of Taimur Sound, which I named Actinia Bay, from the large number of actinia which the dredge brought up there. It is, besides, not the only place in the Kara Sea which might be named from the evertebrate life prevailing there, so unexpectedly abundant.
Unfavourable weather detained us in Actinia Bay, which is a good and well-protected haven, till the 18th August, during which time excursions were made in various directions, among others farther into Taimur Sound, where a variable strong current was found to prevail. The Sound is too shallow to be passed through by large vessels. The rocks round Taimur Sound consist of gneiss strata, which form low ridges that have been so shattered by the frost that they have been converted into immense lichen-clad stone mounds. Between these stretch extensive valleys and plains, now free of snow, if we except a snow-drift remaining here and there in the hollows. The plains were all covered with a very green continuous vegetation, which however on a closer examination was found to be not a true turf, but a mixture of grasses, allied plants, and a large number of different kinds of mosses and lichens. Actual flowers were found here only sparingly.[193] In this respect the coast tundra shows a remarkable difference from the coast lands on Vaygats Island and Novaya Zemlya. On the other hand, the abundance of luxuriant lichens and mosses was striking. The mosses along the beach and the borders of the snow-drifts remaining here and there bore fruit in abundance. Animal life on land was scanty; some few reindeer were seen, a mountain fox was killed, and a lemming caught.
Only the following birds were seen: owls (Strix nyctea) rather numerous, of which one was killed; a species of falcon, which was hunted unsuccessfully; snow buntings, breeding very generally in the stone mounds; a covey of snow ptarmigan, of which some young birds were shot; six species of waders, the most common birds of the region, of which a large number were shot; two kinds of gulls (Larus glaucus and tridactylus); Lestris parasitica and Buffonii, the latter the more common of the two; Anser bernicla, very common; and finally the long-tailed duck (Harelda glacialis) in great flocks swimming in the Sound. Bird life, viewed as a whole, was still scanty here, in comparison with that which we were accustomed to see in the northern regions west of Novaya Zemlya.
In the sea the higher animal life was somewhat more abundant. A walrus had been seen during the passage from the Yenisej, and on the ice drifting about in the Sound a number of seals, both Phoca barbata and Phoca hispida, were observed. This gave rise to the supposition that at the sea-bottom animal life was richer, which was also confirmed by the dredging yield. Nowhere was seen on our arrival any trace of man, but a cairn now indicates the place, off which the Vega and the Lena were anchored.
In this sea never before visited by any vessel, however, we were nearly coming in contact with a countryman. For while we lay at anchor in Taimur Sound, Captain Edward Johannesen came into the neighbourhood of the same place with his sailing vessel Nordland from Tromsoe. He had left Norway on the 22nd May 1878, had come to Gooseland in Novaya Zemlya on the 6th June, and had reached the northernmost point of that island on the 22nd July. Here loud thunder was heard on the 26th July. On the 10th August he steered eastwards from Novaya Zemlya across the Kara Sea between 76° and 77° N.L. in open water. On the 16th he had the Taimur country in sight. Here he turned, and steered first to the west, then to the north. In 77° 31' N.L. and 86° E.L. from Greenwich he discovered and circumnavigated a new island, which was named "Ensamheten" (Solitude). The island was free of snow, but not overgrown with grass. The animals that were seen were some bears and bearded seals, terns, fulmars, ivory gulls, flocks of black guillemots, and a "bird with a rounded tail and long bill," probably some wader. On the north-east side of the island a strong northerly current prevailed. The remote position and desolate appearance of the island gave occasion to the name proposed by Johannesen. Hence Johannesen sailed with a great bend to the north, which brought him to 78° N.L., back to the northern extremity of Novaya Zemlya, and thence on the 12th September to Norway. During the return voyage across the Kara Sea also scarcely any ice was met with.[194]
