It is true that in addition to the men who are actually working the tractors we ought to take into account the workers who are employed in the workshops where the tractors are made, those who are employed in getting petroleum, etc., before we decide how many desyatinas of land one men can plough. This will somewhat reduce our estimate of the advantage of tractor ploughing, but the adventage will still remain exceedingly great.
