Nevertheless, the group is inhabited, and the number of Europeans and Americans who formed the nucleus of the Kerguelen population at the date of the 2nd of August, 1839, had been augmented for two months past by a unit in my person. Just then I was waiting for an opportunity of leaving the place, having completed the geological and mineralogical studies which had brought me to the group in general and to Christmas Harbour in particular. Christmas Harbour belongs to the most important islet of the archipelago, one that is about half as large as Corsica. It is safe, and easy, and free of access. Your ship may ride securely at single anchor in its waters, while the bay remains free from ice. The Kerguelens possess hundreds of other fjords. Their coasts are notched and ragged, especially in the parts between the north and the south-east, where little islets abound. The soil, of volcanic origin, is composed of quartz, mixed with a bluish stone. In summer it is covered with green mosses, grey lichens, various hardy plants, especially wild saxifrage. Only one edible plant grows there, a kind of cabbage, not found anywhere else, and very bitter of flavour.
