nary steel wire about a yard in length, which is provided with a 

 single handgrip at each end, which he pulls rapidly back and 

 forth around a chair or table leg, the wire thus burning a groove 

 into the wood. 



"A small wire is used on trees, to the end of it being attached 

 cables run by an engine or motor. 



"In cutting down trees the cable is chosen long enough to 

 make it possible to place the machine out of reach of the falling 

 tree. The machine may also be used in cutting logs or timber 

 already felled, in which case a shorter cable may be used. The 

 power required for European varieties of wood range from 1.5 

 to 7 horsepower, depending upon the hardness and dimensions of 

 the timber. A 4-horsepower machine is said to cut down a pine 

 2 feet in diameter in about 5 minutes. The machine requires 

 less than one-half of the time required for sawing down a tree 

 by hand and about two-thirds of the time required for sawing 

 logs or timbers that are lying on the ground. In the case of 

 larger stems the machine requires only about one-fourth the time 

 for sawing by hand. 



"The wires are cheap and the whole machine with motor costs 

 $650." 



A manufacturer of wood block paving machinery has sug- 

 gested that "the most economical way to get out blocks is for 

 several miles in one city or, say, within a radius of ten to twenty 

 miles, to put in small block machines right near the edger where 

 the regular crew can do the cutting. Then, by shipping their 

 blocks to a central creosoting plant, all the mills so doing can 

 save a great deal in fixed charges, fuel, and many other ex- 

 penses which otherwise would be incurred."
