wheatgrowing

Improvements may easily be imagined which would annihilate vast portions of the productively invested wealth of individuals; such (e. g.) as a mechanical invention that superseded railways in England, or a development of trade that rendered English wheatgrowing unprofitable: and economic changes of this kind, though smaller in degree, are continually occurring.

Thus, while the recent fall in the value of English wheat, in consequence of the development of foreign production and trade, has led to a marked diminution in the area of wheatgrowing land in England, I cannot find that it has led to anything like an equally discernible change in the amount of capital economically applicable to the land that still grows wheat.
