The apartment for the hot-water boiler may be utilized as a coal-house, and for the barrows, forks, shovels, buckets, and other tools which form the necessary outfit of a stable-yard. Slow-combustion stoves are now made with a boiler sufficient to supply hot-water pipes for the coachhouse and harness-room. It may sometimes be possible to combine an auxiliary pipe for the coach-house with a set for the green-house, but it is not desirable to sacrifice convenience in other respects for this purpose.
