Assuming that 9,000 lb. of dry hay are necessary for keeping one head of horned cattle every year, the following figures (taken from Toubeau’s Répartition métrique de impôts) willshow what we obtain now under usual and under intensive culture:
| Crop per acre. Eng.lb | Equivalent in dry hay. Eng.lb | Number of cattle fed from each100acres. | |
|---|---|---|---|
| Pasture | -- | 1,200 | 13 |
| Unirrigated meadows | -- | 2,400 | 26 |
| Clover, cut twice | -- | 4,800 | 54 |
| Swedish turnips | 38,5000 | 10,000 | 108 |
| Rye-grass | 64,000 | 18,000 | 180 |
| Beet, high farming | 64,000 | 21,000 | 210 |
| Indian corn, ensilage | 120,000 | 30,000 | 330 |
