Note 23 — Art. XV. On the Revolving Steam-Engine.

But it is not necessary (as in the plate) to crowd the engine into the after-part of the boat, the boilers maybe placed forward, and near them, or over them, the cylinder, &c. The power is then communicated to the stern-wheel by a long shaft, supported on, or immediately under, the deck. This arrangement gives room for loading both behind and before the boilers and engine, and equalizes the burden. This is the actual arrangement of the Merrimack boat.
