      It was a false alarmthere was no fire! Larry decided.He shook hands and accepted the lounging chair Dick offered.


      Thats so. But somebody said she did, or thought she must know the real ones.But patience is always rewarded!


      Yes, Dickthe beginning of Gaston, we thought.

      The airplane, selected for its wing-camber and span that gave it a low landing speed and good sustentation, was not fast.They took me to two officers who stood near the bridge, and told them that I "pretended" to be a Netherland journalist. Having proved this by my papers, the officers gave me an escort of three men, who conducted me to the bridge-commander, on the other side of the Meuse.

      It remained only to get information, he stated, and then went up.Presently Jeff looked up at them.


      There goes the chute! Dick was equally thrilled.

      A set of lathe tools should consist of all that are required for every variety of work performed, so that no time will be lost by waiting to prepare tools after they are wanted. An ordinary engine lathe, operating on common work not exceeding [126] twenty inches of diameter, will require from twenty-five to thirty-five tools, which will serve for every purpose if they are kept in order and in place. A workman may get along with ten tools or even less, but not to his own satisfaction, nor in a speedy way. Each tool should be properly tempered and ground, ready for use 'when put away;' if a tool is broken, it should at once be repaired, no matter when it is likely to be again used. A workman who has pride in his tools will always be supplied with as many as he requires, because it takes no computation to prove that fifty pounds of extra cast steel tools, as an investment, is but a small matter compared to the gain in manipulation by having them at hand.

      Cutting, as a process in converting material, includes the force to propel cutting edges, means to guide and control their action, and mechanism to sustain and adjust the material acted upon. In cutting with hand tools, the operator performs the two functions of propelling and guiding the tools with his hands; but in what [58] is called power operations, machines are made to perform these functions. In nearly all processes machines have supplanted hand labour, and it may be noticed in the history and development of machine tools that much has been lost in too closely imitating hand operations when machines were first applied. To be profitable, machines must either employ more force, guide tools with more accuracy, or move them at greater speed, than is attainable by hand. Increased speed may, although more seldom, be an object in the employment of machinery, as well as the guidance of implements or increased force in propelling them. The hands of workmen are not only limited as to the power that may be exerted, and unable to guide tools with accuracy, but are also limited to a slow rate of movement, so that machines can be employed with great advantage in many operations where neither the force nor guidance of tools are wanting.

      Sandy, not fully aware of the situation, but tense, thought of his chute, in the seat-pack. Would there be time? Could he use it? He waited, watching Jeff and Larry.
