It is universally admitted, we believe, that every boiler that is large enouo-h toadmit a maa should be provided with at least one man-hole. In boilers that are toosmall to be entered, the man-hole is not so useful ; but in these cases it should bereplaced by a number of hand-holes, judiciously placed, through which the interior ofthe boiler may be examined, and scale-matter and other deposits removed. A man-hole is not intended for ornament, but for use ; and hence it should be con-venient of access, and large enough to admit a man of ordinary size.

If it is really necessary toeconomize space to such an extent, a trap door should be cut through the floor over theman-hole, so that access to the interior of the boiler may be as easy as possible. Wespeak feelingly about the inspector, because we have frequently seen the difficulty fromhis point of view. He is not the only one to be considered, however, for it stands toreason that your own engineer, unless he is a gymnast or a contortionist, will not openup your boiler and clean it out any oftener than he has to, if you handicap him when the space above the boiler is ample, it is not uncommon to find the
