Any stipulated quan- tity from six to twelve pounds per foot can be forced in, according to the specification and kind of timber, but, owing to the variation in the grain of different wood, one piece may, of course, absorb more or less oil than another, but the average will be reached, and all will be found impregnated with the spirit of the creo- sote, which completely sterilizes the wood, thus preserving from decay the sap wood as well as the heart. It is desirable that wood should not be cut nor the face removed after creosoting if it can be avoided, as the heavier and more valuable part of the creosote oil will be nearest the sur- face. It is claimed that the mere superficial. Creosoting Tank Ready for Closing. coating of wood by dipping or steeping in creosote oil or applying it by a brush is of no use whatever as a preservative. The two illustrations show the tank employ- ed for creosoting timber. The Canadian import duty on lubricating oils has been reduced from 5 cents to 2% cents per gallon. The Canadian import duty on pails and tubs of wood has been advanced from zq to 25 per Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Don Mills, Ont. : Southam Business Publications
