also required in manipulating the bolts so that they will be pro- 

 perly presented to the keen edge of the quick falling knife. 



The advantages of this kind of mill are many. It can be 

 readily moved from one part of the forest to another so that 

 thereby a great deal of "junk" can be utilized which would other- 

 wise be discarded and left to rot in the woods. This advantage 

 is especially true in regard to the short butt ends of telephone 

 poles and piling, affected with center rot, which at present can be 

 used for no other purpose. This type of mill even makes pos- 

 sible the use of the shell of decayed butts down to 5 inches in 

 thickness. 



There is no waste in kerf or sawdust or in trimmed ends and, 

 therefore, from the same amount of timber a greater number of 

 shingles can be produced by this type of mill than by a sawn 

 shingle mill. The shingle produced is of high grade, has a 

 smooth surface, and is always a quarter-cut shingle. 



2. A Log Pipe Plant in Washington. 



At Curlew, Washington, not far from the Canadian boundary, 

 there is a most interesting establishment turning out solid wooden 

 pipes from ten foot logs. 



While making the customary wait there recently for the down 

 train, I strolled up the dusty main street of the village and was 

 attracted by the chug chug of a gasoline engine to a spacious 

 shed, not unlike a blacksmith shop in appearance. On closer 

 approach, I found outside the shed a pile of small Douglas fir 

 and western larch peeled logs, each 10 feet long and from 8 to 10 

 inches in diameter. From their very slight taper and the absence 

 of knots they seemed to have been cut from trees which had been 

 naturally well pruned in a close growing stand. 



At the back of the shed two men were loading the logs, now 

 converted into neat looking wooden pipes, onto a wagon. 



Within the shed I found that a 5 H. P. gasoline engine fur- 

 nished all the power for the simple plant, which at that time was 

 being operated by only one man. First, a peeled log was placed in 

 a trough-like receptacle where it was held firmly during the pro- 

 cess of boring. This operation removed a core, 4 inches in 

 diameter, from the center of the log and was performed by a 

 special boring instrument slightly more than 5 feet long. The
