ONE:He left his support, swam across the smaller channel, carefully, and secured the life preserver which had dropped into a heavy clump of the grass and then had floated free of the mud, held only by the end of a tangled stringand the skin of an empty, oilskin pouch, torn and ripped to tatters, that hung to the cord."Why do you foist me off with paste jewels?" Maitrank asked, coolly. "Ah you may stare with amazement! You are a very clever actress, madam."
TWO:"Knowledge is power," said Lawrence, "so long as you keep it to yourself. Why did you tell me that you had never heard of the tuberose perfume?"A learner should, in fact, consider the application and operative conditions of gearing as one of the main parts of the subject, and the geometry or even the construction of wheels as subsidiary; in this way attention will be directed to that which is most difficult to learn, and a part for which facilities are frequently wanting. Gearing may be classed into five modificationsspur wheels, bevel wheels, tangent wheels, spiral wheels, and chain wheels; the last I include among gearing because the nature of their operation is analogous to tooth wheels, although at first thought chains seem to correspond more to belts than gearing. The motion imparted by chains meshing over the teeth of wheels is positive, and not frictional as with belts; the speed at which such chains may run, with other conditions, correspond to gearing.
