Here was seen in operation the process of turning wet pulp to various grades of paper, from the manipulation of the pulp in the "beaters," the flowing across the wires, the drying, and winding. More than ordinarily interesting was the presentation to all visitors of samples of excellent blotting paper recently taken from the machine— the first of the product, by the way, to be made in the Dominion.

Here was seen in operation the process of turning wet pulp to various grades of paper, from the manipulation of the pulp in the "beaters," the flowing across the wires, the drying, and winding. More than ordinarily interesting was the presentation to all visitors of samples of excellent blotting paper recently taken from the machine— the first of the product, by the way, to be made in the Dominion. There was seen also the Depart- ment of Timber tests where a Hatt- Turner Impact testing machine, a 30,000 lb. Olsen Universal machine, a lb. Wicksteed and 150,000 lb. Emery machines are available for experiments in establishing the strength characteristics of important Canadian wood species. The testing proceedure includes eight strength tests, static bending, compression parallel to grain, compression per- pendicular to grain, shear, tension, impact bending, cleavage and hard- ness. Important work has been ac- complished here in the testing of Nova Scotia mine timbers. Timber physics forms yet another major di- vision of the laboratories in which the equipment includes microtome, microscopes, photomicrographic ap- paratus, projection lantern, cameras, electric ovens, autoclave, balances and so forth. The work has to do largely with determining the physi- cal and structural properties of wood by extended and varied tests. The Division of Wood Preservation was organized in October, 1914, and includes the study of wood preser- vatives and methods of treating wood to prolong the life of railroad ties, paving blocks, etc. Curbing the Waste. The inspection of the Laboratories was followed by a number of brief addresses. Hon. Dr. Roche expres- sed the sense of satisfaction he felt in having brought into existence during his administration of the De- partment of the Interi
