An important industry, according to La Nature, has sprung up within the last few years in the French department of Landes, It consists in extraction and applications of oils from pine. These oils are of two sorts, the heavy (pinoleum), obtained by distilling the resinous wood at a low temperature, and used for painting and wood-preserving; and the light oil for illumination, got by distilling in special apparatus, and purified with chemical agents. This light oil has the same chemical composition as oil of turpentine (C20H16), and distils at the same temperature (150° to 160°), but has the advantage of not resinifying. It contains neither pinic nor sylvic acid. As it. does not emit vapors except at a high temperature, its use for lighting purposes is quite safe. Its luminous intensity is greater than that of petroleum;. it contains 88 per cent. of carbon, while petroleum has 82 per cent. Two similar burners showed the pine oil to have an advantage of 33 per cent. in luminous intensity; the consumption was also less.

In the department of Landes roots and old stumps of pine, formerly unutilized, are now made to render considerable quantities of oil.
