The only brick required is in the founda-tion and around the grate, fire brick being, of course,used in the latter place. The tubes all being short thereis very little expansion. One interesting feature aboutthe boiler is the circulation, which, it is claimed, is kept up between the top and bottom. The feed water entersat the top mud and steam drum. From there it flowsdown through the four water tubes in the bottom of thedrum to the bottom of the boiler, thence up to the firstset of tubes and then back to the steam drum. Thiscirculation, if kept up, will keep an even temperature inall parts of the boiler, and, it is said, will prevent All things considered there are many desirable features,and would appear to be a very efticient and durable typein places where the scale difliculty is not too great; andon this point the manufacturers claim almost absolutefreedom, owing to the rapid and complete circulation.
