The growth of the plant is slow, and its durability proportionately great, its death being determined generally by that of the tree on which it has established itself.
The principal supply is in West Rutland, Proctor and Pittsford; this, the "Rutland marble," is a duller, less lustrous white, and of a greater durability than the Carrara marble, and is used largely for monuments and statuary.
Most woods in durability, and none stand better alternate exposure to drought and moisture, while under cover it is nearly indestructible as long as dry-rot is prevented by free admission of air.
Pedunculata as far as durability in water is concerned; but when grown under favourable circumstances the sessile oak is certainly equally lasting if kept dry.
The wood is hard, heavy and of fine grain, quite equal to the best British oak for indoor use, but of very variable durability where exposed to weather.
