This view, it is hoped, will not lead to anything in the book being construed as a disparagement of the importance of theoretical studies.Coming closer as it dropped lower, the amphibian circled in a tight swing over the fairway several times and finally straightened out, flying toward the wind that came from almost due North on this first cool day after a humid July week, and began to grow smaller to the watchers.

      No human hand touched the switch that ran that door down!

      Drilling, more than any other operation in metal cutting, requires the sense of feeling, and is farther from such conditions as admit of power feeding. The speed at which a drill may cut without heating or breaking is dependent upon the manner in which it is ground and the nature of the material drilled, the working conditions may change at any moment as the drilling progresses; so that hand feed is most suitable. Drilling machines arranged with power feed for boring should have some means of permanently disengaging the feeding mechanism to prevent its use in ordinary drilling.
