the work of such a system as the one shown in our illustration is shown more clearly and to better advantage by making separate elevations of different parts of the work, viewing the several parts from the most advantageous position, rather than to show it all in one elevation. However, it sometimes happens

which the stacks pass through the roof brings to mind the fact that a roof plan is sometimes very useful in showing this location.
