ON THE USE OF STEAM POWER IN FORESTRY. 273 



are persuaded that the use of the road locomotive may be made a 

 source of great gaiu. To those who give the latter a trial, in a year 

 or two they will be surprised to find the large amount of profit 

 arising from its use in all work connected with forestry to which 

 'it is applicable. 



In conclusion, a word may be said with regard to the engines 

 themselves. They should always be of the best material, which 

 implies lightness as well as durability. From 6 to 10-horse power 

 are proved to be the most serviceable for all purposes ; even on turn- 

 pike roads an engine over 10-horse power is cumbersome. Aveling 

 and Porter, Eochester, England, are the best makers of road loco- 

 motives ; but as we have no experience of their common portable 

 engines, we would recommend those made by Hornsby, Grantham, 

 as being complete in almost every particular.
