Is the reason (as we said) because wheat takes up more nourishment; and barley cannot bear so much, but is choked with it?

Or is the one temperament congruous and harmless to wheat, because it is hot; and the other to barley, because it is cold? Or are men afraid to sow wheat in a dry soil, because of the ants, which presently lie in wait for it; but they cannot so easily deal with barley nor carry it away, because it is a larger grain?
