[AS.] A black, sticky liquid, distilled from pine trees and from coal. When charcoal is produced, an arrangement is made for collecting far. From wood tar is distilled wood-vinegar or pyro-lignean acid, from which is produced wood-naphtha. Wood-tar is got from the Scotch fir, the Siberian larch, and other fir-tree roots. Coal-tar is a product in making gas, and yields crude naphtha and pitch. Mixed with wood-naphtha, crude naphtha is a solvent of resins. Benzole, carbolir. acid, and aniline colors are all obtained from coal-tar. (See Coal-tar.)
