THREE:In the centre of it all sat Leona. Lawrence could see now that there were marks and bruises on her face, the result of the autocar accident, which showed out now there was no artist to attend to them.I dont know, Jeff spoke dubiously, uncertainly. Weve gone over all the things we can think of that might go wrongbut

Well-minded persons, who are willing to perform these duties, are urgently requested to present themselves at the town-hall to-day at four o'clock in the afternoon.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.
TWO:(1.) If milling tools operate faster than planing or turning tools, why are they not more employed?(2.) How may the effect produced by cutting tools generally be computed?(3.) To what class of work are milling machines especially suited?(4.) Why do milling processes produce more accurate dimensions than are attainable by turning or planing?(5.) Why can some branches of manufacture be said to depend on milling processes?
