The rear end is oval, the lower portion extending below far enougli to hold theshort tubes leading from the furnace to the back connection. The furnace is brick-lined, andcan be detached when desired. The fire-brick are held in place by iron rods, which are pro-tected from the fire and can be removed and replaced when necessary. The cylindricalcrown-sheet gives a large effective lieating surface, and is always fully protected by are no water sides to fill with sediment, and the fire-brick lining of the furnace insuresa very high degree of temperature and combustion of the gases, and consequent economy infuel. TheEconomizer Boiler.—Another semi-portable boiler, known as the by the Porter Mfg. Co., Syracuse, N. Y., is shown in Fig. 8. It is largely used for Section 15 5edimihrru^h C D Tig! WrJn-U-m KALEVI
