4. Third Comer - Further Rise of Rent
The third comer has to use the two-bushel land (which now becomes the margin). Wages on all lands are now two - for that is the most that can be had without the payment of rent. If the third comer wanted to work on the three-bushel land, its owner would take one bushel as rent. The rent represents what the landowners can get without working, but solely by virtue of their ownership.
