"The star-spangled banner! O, long may it wave!--" "Don't laugh, dear," Hetty whispered. "The place haunts, me. I never seem to be able to get away from the horrors of it. And last night----" Here was the gas meter under the stairs as usual. Behind it was the grimy, dirty card, which showed no entry for years. It was marked "taken 5 Feb.," in other words the meter had been read the day the owner had disappeared. By reading the index Prout saw that a hundred odd cubic feet of gas had been used since. Lawrence gave the necessary information. He was a little surprised to hear that his hostess had never heard of the tuberose. Nor, fond of flowers as she seemed, did she appear in the least interested. Let the reader compare a hammer with a wheel and axle, inclined plane, screw, or lever, as an agent for concentrating and applying power, noting the principles of its action first, and then considering its universal use, and he will conclude that, if there is a mechanical device that comprehends distinct principles, that device is the common hammer. It seems, indeed, to be one of those provisions to meet a human necessity, and without which mechanical industry could not be carried on. In the manipulation of nearly every kind of material, the hammer is continually necessary in order to exert a force beyond what the hands may do, unaided by mechanism to multiply their force. A carpenter in driving a spike requires a force of from one to two tons; a blacksmith requires a force of from five pounds to five tons to meet the requirements of his work; a stonemason applies a force of from one hundred to one thousand pounds in driving the edge of his tools; chipping, calking, in fact nearly all mechanical operations, consist more or less in blows, such blows being the application of accumulated force expended throughout a limited distance. If these various plans of arranging screw-cutting machines had reference to different kinds of work, it might be assumed that all of them are correct, but they are as a rule all applied to the same kind of work; hence it is safe to conclude that there is one arrangement better than the rest, or that one plan is right and the others wrong. This matter may in some degree be determined by following through the conditions of use and application. What! to see thee no more, and to feel thee no more, Higher and higher they went, probably out of sight of anyone without strong field glasses, and while they swung in a wide circle, Larry’s binoculars swept the horizon. “Why, Dick! Wait till everybody was gone, then take to the rubber boat, get himself picked up——” “I corrected the tendency of the wind to turn the crate as we taxied, and I lifted her off and leveled for a couple of seconds so that the prop could bring back flying speed before climbing.” Foster hastened to assure him that two days would easily do it. "We know the country round here, [Pg 113]Colonel, know it better than the hostiles themselves; and a big party of us volunteers to put you on the trail and bring you to them. You can't hardly refuse, seein' as you say you are here to protect us, and this is the protection we ask, to get back the stock we've lost." The boys listened with sinking hearts. More than three times as many rebels as they themselves numbered, and perhaps fiercer and stronger than those they had already encountered. Shorty glanced listlessly from the head of the table toward the foot. There his eye rested on the Second Lieutenant for a minute, and then he muttered to himself, "No, he's no worse than the rest ought to be on me," and shook his head in answer to the Judge-Advocate's formal question. "Don't say that, dad—we care for you very much, and we're coming back."
