I saw lemmings here – “Lummick” to the Lapps – which had grey bodies, black faces, black hind-legs and blackish rumps, very short tails and ears; they feed on grass and reindeer moss, but are not eaten. They live mostly in the mountains but in some years they descend in their thousands down into the forest, go straight across lakes, bogs and morasses, and thus many of them die. They are not especially timid and they whine at passers-by from their holes like dogs. 5 or 6 young, dig holes in the ground, 3 inches long.
