Fuel Economy.—If American locomotives were of a morehighly developed type such as are much employed for foreignservice, if they were designed with compound cylinders or withsuperheaters, the amount of fuel required would be less and theannual coal consumption would be reduced 6,000,000 to 10,000,000tons.—Dr. W. F. M. Goss before A. S. M. E. 288 AMERICAN ENGINEER AND RAILROAD JOURNAL. LUCAS HORIZONTAL BORING, DRILLING AND MILLING MACHINE. HORIZONTAL BORING, DRILLING AND MILLINGMACHINE. The No. 3 Precision horizontal boring, drilling and millingmachine shown in the illustration is giving splendid results inthe railroad shops in which it is being used, because of its ac-curacy and adaptability to a wide range of work. Special at-tention has been given to. the design and construction of thistype of machine to make it as useful for tool room work, requir-ing great accuracy, as for general manufacture, where power andrigidity are the principal essentials. To illustrate its adaptabilitytwo examples may be taken from railroad shop practice; theholes may be bored in a tumbling shaft and the hubs faced par-allel, and true with the holes, by milling at one setting; air pumpcylinders may be bored and both ends faced by milling at onesetting. It will be seen that instead of raising and lowering the platenwith its load, the weight of wh
