To realize increase in or decrease in cost it is considered essential that total mechanized of the logging process must be brought about. By total mechanization is meant that all phases of the operation, from standing tree delivery to the final point of utilization, are carried out by mechanical means and the wood is "untouched by human hands". The intrusion of manual labour at any point production process will prohibit the attainment of the productive potential of a wholly mechanized system. Wherever there have been significant breakthroughs in increasing productivity or in cost reduction in mlnlng, agriculture, and in many kinds of manufacturing, it has been through total mechanization. Mechanization in agriculture has in the past 50 years reduced the man-hours to produce 100 bushels of corn from 135 to 23, to produce 100 bushels of wheat from 106 to 17, to produce a bale of cotton from 276 to 77^2. We can expect the same sort of reduction in labour content with complete mechanization in the forest.
