and while I employed these portions, the rent would remain the same, although the produce of each should have an equal augmentation. If, instead of 100, 90, 80, 70, the produce should be increased to 125, 115, 105, 95, the rent would still be 60, or the difference between
| 95 and 125 = 30 | whilst the produce would be increased to 440 | 125 |
|---|---|---|
| 95 and 115 = 20 | 115 | |
| 95 and 105 = 10 | 105 | |
| — | 95 | |
| 60 | —— | |
| 440 |
But with such an increase of produce, without an increase of demand, there could be no motive for employing so much capital on the land; one portion would be withdrawn, and consequently the last portion of capital would yield 105 instead of 95, and rent would fall to 30, or the difference between
| 105 and 125 = 20 | whilst the produce would be still adequate to the wants of the population, for it would be 345 quarters, or | 125 |

the demand being only for 340 quarters.—But there are improvements which may lower the relative value of produce without lowering the corn rent, though they will lower the money rent of land. Such improvements do not increase the productive powers of the land, but they enable us to obtain its produce with less labour. They are rather directed to the
