Show LOGGING TRUCKS MAKE ROAD One Type of Car Used in Far West Has Front Tires of Ten Inches and Rear Ones of Twenty. Powerful wide-tired trucks are now being used in logging regions in Oregon Ore-gon and Washington, which virtually make their own roads as they go. One type of these cars is described in Popular Popu-lar Mechanics' Magazine. It has front tires 10 inches wide. An experienced experi-enced driver carefully selects his course as he goes over a route for the first time and the weight of his machine ma-chine makes a road as it moves along. A few trips over the same line of travel serves to make a hard, smooth, surface which will withstand considerable consid-erable bad weather. Four-wheeled trailers are often used with these trucks. |
