Southeast. The original machine was invented by Horace V. But- 

 ters, of Ludington, Mich., in 1883. It was a crude device, which used 

 manila rope for skidding lines; improvements made from time to 

 time have brought it 

 to its present state of 

 efficiency. 



The first Lidger- 

 wood overhead skid- 

 der on the Pacific 

 coast was introduced 

 in 1904. It was of 

 the tree- rigged type 

 and was the largest 

 machine of this de- 

 sign built up to that time, having 10 by 12 inch skidding and 9 by 

 10 inch loading engines. While it did fairly satisfactory work from 

 the beginning, several changes had to be made to adapt it to the 

 new conditions. For the last 10 or 11 years it is said to have done 



satisfactory work. In 

 1907 several 12 by 12 

 inch overhead skidders 

 were installed in the 

 region. The following 

 year a 12 by 12 inch 

 skidder of a heavier 

 type was introduced, 

 and this is the type of 

 machine that is now 

 being used by a num- 

 ber of operators. The 

 manufacturers of the 

 skidder are now build- 

 ing a 13^ by 16 inch 

 tree-rigged machine, 

 which they hope will 

 successfully handle any 

 log required by the 

 conditions in this re- 

 gion. During 1916 at 

 least five coast opera- 

 tors purchased steel- 

 tower skidders. 



Machines. — The tree-rigged machine of the type that has been 

 installed within the last few years is made up of two sets of double 

 engines, one for skidding and one for loading.
