ONE:"I will show you where she is," he said hoarsely.It may be assumed that the same conditions apply to the standards of a common planing machine, but the case is different; the upright framing is easily made strong enough by increasing its depth; but the strain upon running joints is as the distance from them at which a force is applied, or to employ a technical phrase, as the amount of overhang. With a moving platen the larger and heavier a piece to be planed, the more [132] firmly a platen is held down; and as the cross section of pieces usually increases with their depth, the result is that a planing machine properly constructed will act nearly as well on thick as thin pieces.
THREE:Modern agnosticism occupies the same position with regard to the present foundation and possible future extension of human knowledge as was occupied by the ancient Sceptics with regard to the possibility of all knowledge. Its conclusions also are based on a very insufficient experience of what can be effected by experience, and on an analysis of cognition largely adopted from the system which it seeks to overthrow. Like Scepticism also, when logically thought out, it tends to issue in a self-contradiction, at one time affirming the consciousness of what is, by definition, beyond consciousness; and at another time dogmatically determining the points on which we must remain for ever ignorant. It may be that some problems, as stated by modern thinkers, are insoluble; but perhaps we may find our way our of them by transforming the question to be solved.
THREE:enwrapt, the lightning wieldest;Assuming, for example, that a machine will cost as much as the wages of an attendant for one year, which is not far from an average estimate for iron working machine tools, and that interest, wear, and repairs amount to ten per cent. on this sum, then the attendance would cost ten times as much as the machine; in other words, the wages paid to a workman to attend a machine is, on an average, ten times as much as the other expenses attending its operation, power excepted. This assumed, it follows that in machine tools any improvement directed to labour saving is worth ten times as much as an equal improvement directed to the economy of first cost.
