Larch, or Larix, is a genus of hardy, deciduous, coniferous trees of very graceful habit. They bear monoecious flowers, the male catkins being small and oval, whilst the female ones are much longer. The leaves are bright green, linear, soft, and usually produced in short bundles on each side of the spray. They appear very early in the spring. The timber, which is very hard and tough, is much used in shipbuilding and for railway sleepers, and in cabinet work is capable of taking a very high polish. The species most commonly planted is 'L. europaea', whcich grows to about 100 ft in height. Other species are 'L. occidentalis', a tall and handsome American tree and 'L. laricina', the tamarack, or hackmatack, of North America. This is a straggling tree, most common in swampy soils, with smaller cones than has the the European species. It reaches a height of 70 ft., and the wood is valuable for the same purposes  as that of other larches.

A lemming is a small, yellowish-brown rodent, closely related to the vole, and belonging to the genus Myodes. The Norwegian lemming (M. lemmus) is about five inches in length, with the tail extremely short. It excavates shallow burrows in the soil of the mountain meadows in which it lives, and in winter tunnels beneath the snow for its food, which is wholly vegetable, consisting of roots, shoots, catkins, moss, and lichens. Special interest attaches to this rodent from the fact that at irregular intervals, varying from five to twenty years, it suddenly appears in vast numbers in Northern Europe; great bodies, said to number millions of individuals, migrate from place to place in search of food, leaving behind them a track of desolation as they eat their way through fields of corn and grass. They show a remarkable persistency both in the act of migration and in the general direction of the movement, and swim without hesitation any bodies of water which may block their path. As, from the contour of the Scandinavian peninsula, they inevitably come eventually to the sea, those which have not perished from overcrowding, from disease, or from the attacks of their enemies, die in attempting to swim across it. The lemming of Northern Europe is known is replaced in North America by the allied M. obensis and the banded lemming (Cuniculus torquatus); the latter is circumpolar, and turns white in winter. Other allies, called lemming-mice, inhabit Northwestern Canada, and have somewhat similar habits, but rarely, if ever, migrate from their habitat.
