might give them time to recover with profit whatever they should lay out in the further improvement of the land. The expensive vanity of the landlord made him willing to accept of this condition; and hence the origin of long leases.

Even a tenant at will, who pays the full value of the land, is not altogether dependent upon the landlord. The pecuniary advantages which they receive from one another are mutual and equal, and such a tenant will expose neither his life nor his fortune in the service of the proprietor.

But if he has a lease for a long term of years, he is altogether independent; and his landlord must not expect from him the most trifling service beyond what is either expressly stipulated in the lease or imposed upon him by the common and known law of the country.
