717. The artists or architects of gardens, in Britain, are of three classes. First, head-gardeners, who have laid out the whole or part of a residence, under some professor, and who commence artist or ground workmen, as these are generally denominated, as a source of independence. Such were Brown, White, &c. Secondly, architects who have devoted themselves chiefly to country buildings, and, thus acquiring some knowledge of country matters, and the effects of scenery, combine with building the laying out of grounds, depending for the execvition of their ideas on the practical knowledge of the gardener pro tempore. These are commonly called ground-architects. Such was Kent. Thirdly, artists who have been educated and apprenticed, or otherwise brought up entirely or chiefly for that profession. These are often called landscape-gardeners; but the term is obviously of too limited application, as it refers only to one branch of the art. Such were Bridgeman, Emes, &c.
