5. _The main forms of wealth whose usufruct is still sold under long renting contracts are land and its more durable improvements._ In England farms are let under long leases, a very common form being the thirty-year lease. Under the old, almost fixed, conditions in agriculture such a lease was equitable, but when prices are rapidly changing and when new methods are being introduced, it gives rise to great hardships. About twenty-five years ago, the great fall in the price of agricultural products brought ruin to many of the tenant farmers. The land troubles in Ireland have been largely about tenants' improvements. When the lease expired, the landlord could appropriate all the improvements that the tenant had made. In America farms are let usually on shares, and from year to year, but the plan of a money rent is increasingly followed. The difficulty of getting an equitable arrangement between landlord and tenant is recognized by all. The landlord must make the proper repairs or see that they are made; he must specify in the contract whether the products can be taken away or are to be fed on the place so that the soil may not be impoverished, and he must provide for the purchase of other fertilizers. On the other hand, the tenant under the renting contract has little motive for improvement, and many occasions for discontent. So in America, far more than in the older countries, land changes hands by sale, the purchaser going into debt for it, giving his note and paying interest on the loan rather than rent for the farm. [Sidenote: But many other goods are rented] Many less durable goods are rented for brief periods. Carriages are rented for the day, bicycles by the week or month. Sewing-machines, boats, guns, tents, and even diamond engagement rings, yield their joys under the renting contract. People frequently hesitate between the renting and the purchase of a piano, and in some cases renting is the more convenient and desirable way of securing its use. The purchase of a dress-coat or of a masquerade-suit to be worn but once, involves for some an excessive and needless sacrifice. For a moderate sum its temporary use may be had, and it is then returned, little the worse for wear, to the accommodating clothier. [Sidenote: Economic rent much wider than the renting contract]
