 lifted by new patent lifting machines. The saws are called treble 



circulars, which nevertheless have four saws, two of them being used 

 to slice off part of the top of a log eight feet through, so that the 

 part to be cut by tlie main saws shall be less than six feet in depth. 

 By an ingenious adaptation of the Alpine tindjer shoot, vessels are 

 loaded at spots where there is no harbour.
