Founded by Stephen Van Rensselaer in 1824, the first engineering school that has had a continued existence to be founded in America. The old buildings were de- stroyed by fire in 1904, so that the pres- ent buildings are new, well arranged, and well equipped with modern appara- tus.

RENT, a sum of money, or other valu- able consideration, payable periodically for the use of lands or tenements; the return made to the owner by the occupier or user of any corporeal inheritance. It does not necessarily consist in money. Adam Smith considers rent as the price paid for the use of land. Ricardo and his followers considered that the rent of superior soils is equal to the difference between their produce and that of the worst soils cultivated. There is great doubt as to the accuracy of this view. Land let by a landlord to a ten- ant for purpose of cultivation is anal- ogous to money lent to a borrower. The rent of the land is virtually the interest on the land viewed as a loan. See Single Tax.
