Wood is a heterogeneous, hygroscopic, cellularand anisotropic(or more specifically, orthotropic) material. It consists of cells, and the cell walls are composed of micro-fibrils of cellulose(40–50%) and hemicellulose(15–25%) impregnated with lignin(15–30%).
Mahogany. Mahogany is a straight- grained, reddish-brown timber of three tropical hardwood species of the genus Swietenia, indigenous to the Americas [ 1] and part of the pantropical chinaberry family, Meliaceae.

Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees).

Each additional cut is then made parallel to the one before. This method produces the widest possible boards with the least amount of log waste.
