  16. A thick, dark- colored, viscid product obtained by the destructive distillation of organic substances and bituminous minerals, as wood, coal, peat, shale, etc. Wood- tar, such as the Archangel, Stockholm, and American tars of commerce, is generally prepared by a very rude process. A conical cavity is dug in the ground, with a cast- iron pan at the bottom, from which leads a funnel. Billets of wood ( such as pine or fir) are thrown into this cavity, and being covered with turf are slowly burned without flame. The tar which exudes during combustion is conducted off through the funnel. In England wood- tar is chiefly obtained as a by- product in the destructive distillation of wood for the manufacture of wood- vinegar ( pyroligneous acid) and wood- spirit ( methyl alcohol). It has an acid reaction, and contains various liquid matters of which the principal are methyl- acetate, acetone, hydrocarbons of the benzene series, and a number of oxidized compounds, as carbolic acid. Paraffin, anthracene, naphthalene, chrysene, etc., are found among its solid products. It possesses valuable antiseptic properties, owing to the creasote it contains, and is used extensively for coating and preserving timber and iron in exposed situations, and for impregnating ships’ ropes and cordage. Coal- tar is also extensively obtained in the process of gas manufacture. It is a very valuable substance, in as much as the compounds obtained from it form the starting- points in so many chemical manufactures: a sailor is called a tar from his tarred clothes, hands, etc. " Hearts of oak are our ships, jolly tars are our men."- Sea song.
