TREE-FELLING BY STEAM. 



The machine constructed a few years ago by Messrs. Ransome, and 

 which was tried at Roupell Park, near London, seems to combine all the 

 desiderata in the matter of mechanical tree-felling. Many experiments have 



been previously made by people to cut down trees by means of steam 

 machinery, but none of them included all the conditions necessary for 

 success. The Ransome Machine cut down four large trees in forty minutes. 

 The apparatus, as shown in the illustration, is not unlike, in appearance, 

 the perforating machines employed in boring rocks, in which the drill is
