Up to date the com-pany has constructed twelve such stations, locating theseat section camps where store and tool houses are pro- bottom of the stack and the fuse ignited through theflue door, the latter then being closed.

It is said that ordinarily three or four shots willclean a stack. A coal-rationing scheme will shortly be introduced inGreat Britain to compensate for the shortage in coalsupply caused by the going into war service of a largenumber of miners. 424 Electric Railway Journal Vol. 52, No. 10. FOUR-SPINDLE BORING MILL ARRANGED FOR BORINGMOTOR SHELLS, CHICAGO SURFACE LINES Utilizing a Four-Spindle Boring Millto Rehabilitate 3000 Motors Chicago Surface Lines Rebores Four GE-80 Motor-Bearing Seats Simultaneously, With aRecord of Eleven Shells Per Day ON THE Chicago Surface Lines it was for some timethe practice to rebore motor shells on an ordinaryengine lathe. Later a standard horizontal boring millwas used. With either of these machines it was neces-sary to reset the shell and change the boring bar eachtime a shell was bored. In 1917 it was decided to pro-cure a machine which would handle this work more effi-ciently. A four-spindle boring machine built by the Beaman &Smith Company was purchased, and after it had been re-modeled in the Chicago shops it was fitted with Davisexpansion boring bars made especially for this bars run in special guides and have micrometeradjustment of the cutters.
