knows the width of the farm in inches, and even half- 
inch spaces are taken into account in making the rows. 
That is, with many crops the distance from center to cen- 
ter of rows is 123/2 inches rather than 12 or 13. This 
example is given to show how very particular the owner 
is as a garden mechanic. Although often 20 to 30 men 
are working on the farm, every row for every crop is 
marked by the owner. The seed drills are then guided 
over the shallow marks, or the plants are set in them. 
All the small crops are cultivated with hand wheel hoes 
and inter-cropping is practiced extensively. The second 
crop is often well started before the first is harvested. 
At such times the rows are only 634 inches from center 
to center. The reader can readily see how difficult, if not 
impossible, it would be to use a wheel hoe if the spaces 
between the rows were not uniform in width. The 
marker used on this farm is shown in Figure 31. It may 
be purchased of seed-supply houses. The teeth are 
easily adjusted, and the scale on the bar to which they 
are attached makes it possible to space the rows as may
