Within the last few years an important in- dustry has sprung up in the French department of Landes. It consists in the extraction and application of oils from pine. These oils are of two sorts, the heavy (pinoleum) obtained by distilling the resinous wood at a low tempera- ture, and used for painting and wood preserving ; and the light oil for illumination, got by distill- ing in special apparatus, and purified with chemical agents. This light oil has the same chemical composition as oil of turpentine and distils at the same temperature (150 to 160 de- grees), but has the advantage of not turning into resin. It contains neither pinic nor syl vie acid. As it does not emit vapour except at a high temperature, its use for lighting purposes is quite safe. Its luminous intensity is said to be 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 is also less. In the department of Landes, roots and old stumps of pine, formerly unutilized, are now made to yield considerable quantities of oil. CHARCOAL. We have before spoken of the process that has now passed beyond the stage of experiment, for making charcoal from wood and saving dur- ing the operation more in value of various chemical constituents than ikcosts to make the charcoal. The Chicago Tribune in speaking of it says that the Milwaukee, Lake Shore & Wes- tern Kailway Company has sold about 5,000 acres of land near Birnamwood, Shawano coun- ty, Wisconsin, to a number of New York capi- talists. The hardwood therein will be utilized in the manufacture of charcoal, acetic acid and alcohol, and a plant costing $25,000 is to be established at once for this purpose. The capi- talists have s
