This practical idea did not pass into working form, but itseconomy was thoroughly demonstrated through a most inter-esting model test which has been described and illustrated inthis and which effectually substantiated all claims theinventor had originally advanced for his patent. Notwithstanding, however, the general apathy exhibited in. SECTION OF A WATER TUBE FIREBOX DESIGNED BY S. S.

The versatility exhibited by these clever designersis well attested to in the patent reports of the various European t See American Engineer, June, 1909, page 263. December, 1910.

A study of the majority of these devices carries noparticular appeal, but it is an interesting fact that differing fromthe timidity so noticeable here, it appears that each new designwas actually built and given a tryout, and this despite the factthat the greater number must appeal from a disinterested stand-point at least as utter absurdities. Before attempting the full consideration of this now important the cylindrical portion, arranged in the manner with which weare familiar, or, in other words, a fire tube boiler with a
