Three teams of horses needed to pull load out to main road er and never-tired in an emergency, tractors can be run with an extra crew day and night, and thus effect a clean-up on a log haul that would otherwise be impossible. Again where a. cable team and match block or a hoist can be used for a short time only, a tractor can be used until the small "corner" had been cleaned up. A light-weight tractor is essential when lakes, small ponds, or wet muskegs have to be crossed, or where the teams are usually carried in scows to reach the job. Weight on the tractor is needed where the road is hard and the load heavy. This should and can be adjustable at the foreman's discretion. The Mechanism Should be Simple Again the parts and mechanism should be simple. The work is generally far from the machine shop. Some tractors are hard to steer and accidents have happened. A tractor will travel more than twice as fast as a team of hoses, loaded or otherwise, and thus fully double the number of trips that can be made. 50 cords of pulp logs may be considered a reasonable sleigh train-load. Unless the road is properly iced, this load is best carried on six sleighs rather than on five, and saves side cutting. Three trains of sleighs, to save time, should be used with each tractor. A little planning is needed in arranging the loaded sleighs to prevent delay. Turnouts are as usual though fewer are needed and "go back" hills are not required. Sanding is needed a little less than with teams. Sleigh poles and draw-bars which are quickly interchangeable, can be used so that single loads can be brought out of side roads by teams, if de- sired. A great saving in cost is made by using standard sleighs which can be used again elsewhere when needed. The only material changes are in the rutt
