The wood of P. Larix is used in Switzerland for covering the roofs of houses, being cut into shingles of about one foot square, and half an inch in thickness, which are nailed to the rafters. At first the roofs appear white, but in the course of two or three years become perfectly black, and the joints are stopped by the resin which the sun extracts from the pores of the wood, and which renders the roof impenetrable to rain. (Desc. Pinus)
Synonym of Larix decidua Mill.
