Here is a property consisting of a hundred _rubbia_[16] (not quite three hundred acres).

If it were farmed on the proprietor's own account, the cultivation, harvesting, threshing, and storing would amount to the value of 13,550 days' labour.

The wages, seed, keep of horses and cattle, the interest of capital invested in stock, cost of superintendence, wear and tear of tools, etc., would stand him in 8,000 scudi, or 80 scudi per rubbio.

The earth returns sevenfold on the seed sown.

If 100 measures of seed are sown, the return will be 700.
