m CANADA LUMBERMAN and WOOD-WORKER Volume XXV. Number 6. ) TORONTO. MONTREAL JULY. 1905 WINNIPEG, VANCOUVER /Terms, $1.00 Per Year \ Single Copies, 10 Cents TO PREVENT SAP STAIN IN LUMBER. At the request of a subscriber, we have en- deavored to obtain some information regarding the possibility of successfully preventing sap stain in lumber. Our investigations show that many experiments have been made but that most processes which have been successful are too expensive. The Lumber Anti-Stain Company, of Sault Ste. Marie, Mich., have a process which con- sists of dipping the lumber in its undressed condition into a tank containing a certain chemical in a solution of water, or if preferred sprinkling with same instead of dipping. This is done when the lumber is in its undressed state. It is piled after treatment, and any sap in the lumber, whether on the edge or across the face of the board, is thus prevented from staining and the lumber comes out white and bright. This process is very simple and we understand quite successful, but taking into consideration the royalty and the expense of doing the work, it is not generallay con- sidered advantageous. The Yawkey Lumber Company, of Hazel- hurst, Wis., experimented about three years ago with a system of putting sap lumber into vats and steaming it, but they did not carry their investigations into general practice. They found that by piling their lumber in a more open manner it did not stain and con- sequently concluded that the expense of steaming was unnecessary. They have ex- ceptionally good piling ground and get very little stained lumber. A method of steaming lumber to prevent stain has been adopted by the Daniel Shaw Lumber Company, of Eau Claire, Wis. They load, say, 1,500 feet of lumber on to rollers and stick the lumber with ordinary lath, make the load four feet wide, then provide a steam box large enough to hold the load and fitted with iron rollers on the bottom. The load is then rolled into the steamer, the door closed, live steam turned on and the lumber boiled for
