Malthus too--has satisfactorily explained the principles of rent,
and shewed that it rises or falls in proportion to the relative
advantages, either of fertility or situation, of the different lands in
cultivation, and has thereby thrown much light on many difficult points
connected with the subject of rent, which were before either unknown, or
very           understood; yet he appears to me to have fallen into
some errors, which his authority makes it the more necessary, whilst his
characteristic candour renders it less unpleasing to notice.
