(26) THE ALDER

The ALDER (Alnus glutinosa, D.C. ) is an indigenous tree met with commonly on the banks of streams, but of smaller size than the poplars and tree willows; it often, however, attains to 40 or 50 feet.

It is readily propagated by seeds, but throws up root suckers abundantly.

The alder is important as coppice-wood on marshy ground. The wood is soft, white when first cut, and turning to pale red; the knots are beautifully mottled.

It is adapted for piles in embankments and bridges; and charcoal of alderwood is valued in the manufacture of gunpowder.
