The exact position of the plots in the field should be noted by measured distances from the corners of the plot to permanent stakes by the fence, as shown. Stakes left at the corners of the plot invariably become misplaced through intertillage during the growing seasons and being unnoticed may cause damage to harvesting implements. The plots should be a sufficient distance from the fences of the field so as to be free of the headlands and well away from any trees. Keep the boundaries of the plots at right angles. There should be a dividing strip between each plot, so that the treatment of one plot will not be contaminated with that of another and the results will be entirely separate. The size of the plots may vary according to the convenience of the experimenter, but one-twentieth or one-tenth of an acre is usually most satisfactory for farm crops. ^If no platform scales large enough to take a waggon or cart is available, the difficulties of dealing with the harvest of large areas are too great. With small areas, greater accuracy is required owing to the multiplication of any errors in calculating quantities per acre. Fertilizer plots with vegetables and market garden produce may be very small. The shape of the plots should be long and narrow rather than square so as to ensure a better uniformity of soil. Where the crop is in drills particular attention should b
