might appear a mere feather-head. But those who have read his more serious works will have discerned in him a vein of deep poetic pathos. I hardly know anything finer than the apostrophe in which he turns from those
A Sunday walk,

Each cloud-capped mountain is a holy altar;
An organ breathes in every grove;
And the full heart's a Psalter,
II.—STEAM AND HOT-AIR ENGINES.
SMALL steam-engines of from two to ten horse-power are made by a number of engine-builders, and are quite extensively used. They are of varied excellence, like those of larger size, and are well enough known to need no description here. Those of powers of one horse and under suitable for use in the household, for amateurs, etc., are, however, comparatively rare. The danger of explosion, and the requirement of skilled attendants, which in cities the law in consequence imposes, have operated to prevent their use; while, on account of the but little greater cost of the larger and more serviceable machines, makers have preferred to construct the latter. Some of these small engines are, however, made, two of the best designs of which, the invention of Mr. H. S. Maxim, are shown in Figs. 4 and 5. The one illustrated in
