SAWDUST CAR WHEELS.
The Lumberman says—We have been shown a model of a car wheel consisting of an iron rim of seven inches outward diameter by one-half inch thick, fitted with a well proportioned hub, the space between the hub and rim filled with pine sawdust, pressed in so solidly that wc arc ready to believe the assertion that resting the iron rim upon bearings, a pressure equal to 23 tons applied to the hub failed to develop any signs of weakness. We hesitate in these days of progress to assert that anything is impossible, and we begin to think that even sawdust possesses elements of value hitherto unsuspected, and that the day may come when the filled grounds adjacent to all sawmills may be seen to have a great value in the mechanical development and utiisation of the now useless debris placed upon them to get it out of the way. Sawdust car wheels, sawdust bricks, sawdust fence posts j railroad ties, and even sawdust windoAV and door frames, wainscoting and mouldings, begin to appear among the possibilities of the immediate future.
