...second six months of 1938 I anticipate a price of something like $57 a short ton, which is preparatory to $65 for 1939. A price of $65 is not unusual or excessive. In 1925 the price in Canada was $75, although then there was nothing like the demand for pulp for other than news print purposes that there is today. Demand has definitely overtaken supply, and if there is no major international disturb ance, there is nothing can avert an acute shortage in five years' time...
...world responded. In 1933, 161 deep-sea ships cleared Albany. Last year 255 ships dropped down the river to the sea, 625 barges plied up & down the deepened and renovated canal. Total volume of Albany's 1935 harbor traffic: 500,000 tons, chiefly grain, oil, wood pulp, canned goods. About 90% of the world's ships can use Albany's harbor. Latest figures of the U. S. Shipping Board list Albany as eleventh in foreign imports, 21st in total foreign trade...
...possibilities of naval stores. As the price of naval stores declined after the post-War inflation his interest in waste rose. Starting with the common knowledge that wood can be softened and bent by steaming, Inventor Mason finally arrived at the explosion process for reducing wood to pulp. The process...
...first it was thought that the pulp could be made into paper but insulating board soon promised a better use. Backed by a group of Wisconsin lumbermen, Inventor Mason began to experiment with methods of forming and pressing his pulp. Once when he went to lunch he left a wet slab on a hot press, hurried back, when he remembered, to remove it. Meantime a cranky steam valve had permitted the press to grow hotter and heavier with the result that Inventor Mason found, instead of a fibrous board, a dense, grainless, rigid sheet of material, which, in its present...
Different as they are in appearance, the only real difference between the two boards in manufacture is in the amount of heat and pressure applied. In neither case is there anything added to the pulp, the natural lignins in the original wood serving as the sole binder. In its early days Masonite used to sell more insulating board than hard board but a steady accumulation of new uses for Presdwood has changed the story. Last year 100 carloads of Presdwood were sold to Hollywood producers for scene sets, 200 carloads to the automobile industry, another 200 carloads to trailer makers...
