ONE:When their train approached ours they looked out of the windows, or opened the doors, and waved and greeted and shouted at the top of their voices.CHAPTER XIV. "CROWNER'S QUEST." TWO:It may also be remarked that the special knowledge involved in applied mechanics is mainly to be gathered and retained by personal observation and memory, and that this part is the greater one; all the formul? relating to machine construction may be learned in a shorter time than is required to master and understand the operations which may be performed on an engine [8] lathe. Hence first lessons, learned when the mind is interested and active, should as far as possible include whatever is special; in short, no opportunity of learning special manipulation should be lost. If a wheel pattern come under notice, examine the manure in which it is framed together, the amount of draught, and how it is moulded, as well as to determine whether the teeth have true cycloidal curves.

ONE:Lawrence crossed and opened the street door. Prout stood before him. TWO:Presently he walked to an old soap box holding metal odds and ends, washers, bolts and so on. This he up-ended. He sat down, his lean jaws working as he chewed his own gum slowly. Around him, like three detectives watching the effect of a surprise accusation, stood the chums.In the use of hydraulic apparatus for transmitting and applying power, there is, however, this difficulty to be contended with: water is inelastic, and for the performance of irregular duty, there is a loss of power equal to the difference between the duty that a piston may perform and what it does perform; that is, the amount of water, and consequently the amount of power given off, is as the movement and volume of the water, instead of as the work done. The application of hydraulic machinery to the lifting and handling of weights will be further noticed in another place.

ONE:Nothing mattered now, the thing was done, the victory accomplished. In a vague kind of way Hetty heard the cry of rage and disappointment uttered by her companion, she felt the key snatched with cruel force from her hand, there was a whirl of draperies and footsteps flying down the stairs."ENOUGH DESTROYED, ENOUGH DISTRESSED!

ONE:When I was half way between Li��ge and the Netherland frontier, I noticed that the village of68 Vivignes was burning in various places. It is a beautiful spot, quite concealed between the green trees on the slope of the hills, west of the canal. And the finest and largest farms were exactly those ablaze. The fire crackled fiercely, roofs came down with a crash and a thud. Not a living being could be seen. From the windows of the burning houses small white flags hung, and they too were one by one destroyed by the fire. I counted forty-five farms that were burning, destroyed by the raging flames. TWO:170In working to regular scales, such as one-half, one-eighth, or one-sixteenth size, a good plan is to use a common rule, instead of a graduated scale. There is nothing more convenient for a mechanical draughtsman than to be able to readily resolve dimensions into various scales, and the use of a common rule for fractional scales trains the mind, so that computations come naturally, and after a time almost without effort. A plain T square, with a parallel blade fastened on the side of the head, [80] but not imbedded into it, is the best; in this way set squares can pass over the head of a T square in working at the edges of the drawing. It is strange that a draughting square should ever have been made in any other manner than this, and still more strange, that people will use squares that do not allow the set squares to pass over the heads and come near to the edge of the board.
