FORE:I am not aware that any one has defined what constitutes civil engineering, or mechanical engineering, as distinguished one from the other, nor is it assumed to fix any standard here [14] farther than to serve the purpose of explaining the sense in which the terms will be used; yet there seems to be a clear line of distinction, which, if it does not agree with popular use of the terms, at least seems to be furnished by the nature of the business itself. It will therefore be assumed that mechanical engineering relates to dynamic forces and works that involve machine motion, and comprehends the conditions of machine action, such as torsional, centrifugal, intermittent, and irregular strains in machinery, arising out of motion; the endurance of wearing surfaces, the constructive processes of machine-making and machine effect in the conversion of materialin short, agents for converting, transmitting, and applying power."I found you in the road," Balmayne said boldly. "I was going away from here, seeing that my services were no longer required. I happened to find you. I was just in time, for one of the street prowlers was going through your pockets. Probably your fur coat attracted his attention. It is fortunate----"

FORE:Flat or plane joints nearly always admit of adjustment between the fitted surfaces; that is, the material scraped or ground away in fitting can be compensated by bringing the pieces nearer together; but parallel cylindrical joints cannot even be tried together until finished, consequently, there can be nothing cut away in trying them together. Tapering, or conical joints, can of course be trial-fitted, and even parallel fits are sometimes made by trial, but it is evident that the only material that can [149] be cut away in such cases, is what makes the difference between a fit too close, and one which will answer in practice.

FORE:A second point to be noticed in hammers of this class is the nature of the connection with the driving power. In all cases there will be found an equivalent for the elastic helve of the trip-hammereither air cylinders, deflecting springs, or other yielding attachments,interposed between the crank and the hammer-head, also a slipping frictional belt or frictional clutches for driving, as in the case of trip-hammers.The man, before he sank again into silence, uttered one wordor half a word:
FORE:"Come my man, what's your name?" Lawrence panted.If there was a dark mystery any longer it was confined to the Corner House now. Hetty was not likely to see any more of Lytton Avenue. It was fortunate for her that Mamie was so much better in the morning, for as soon as the business of the day had commenced there was a rush of people to Lytton Avenue.
