Dogwood for shuttle blocks is contracted for by the cord in 

 4, 6, and 8-foot lengths — 5 inches at small end; weight about 

 4,000 pounds per cord. Shuttle blocks are cut into sizes from 

 I2| X i-|- X if up to 23 X 2f X 3|. Thirty-five thousand blocks 

 from 12^ to 16 inches long in these sizes weight about 50,000 

 pounds. Timber is wanted free from knots and other defects. — 

 Southern IvUmberman. 



Matches manufactured from Alder worth perhaps $7.00 per 

 thousand instead of from high priced pine is an innovation in 

 Washington. The logs are sawed to 16 inch lengths and cut on 

 a veneer machine instead of being stamped out with delicate dies, 

 which are considerably damaged when knots are encountered. 

 The loss in waste is reduced by the lower cost of the material. —

A new paving block has been invented by A. D. Wilson of 

 Beaumont, Texas. By treating sawdust with refuse of oil refiner- 

 ies, then pressing, a brick is formed which is claimed to be prac- 

 tically indestructible. It is being tested for paving value in that 

 city. — Lumber Trade Journal. 



In the Southern mountain country where Sassafras grows to 

 merchantable size it has an independent market at a price above 

 that of chestnut. It is used for wardrobes, closet linings, and re- 

 frigerators. The odor it is claimed keeps out moths. — Hardwood 

 Record. 



The burning of charcoal in pits in Germany 

 Charcoal gives 500 to 550 pounds of charcoal per 



Data. cord of beech wood or 215 to 250 pounds 



per cord of pine wood. The wood burned 

 is small material 4 to 7 cm. (i|" to 2%") diameter at the small end. 

 In case larger material 7 to 14 cm. in diameter is burned the pro- 

 duction rises to 650 to 680 pounds per cord for beech and to 280 

 to 325 pounds per cord for pine wood.
