He fancied he heard a voice very indistinctly begging his pardon. Again he clutched wildly at a shoulder and merely snapped his fingers. "Strike a light," he muttered, under his breath, "this ain't good enough. It ain't[Pg 92] nearly good enough." Reaching forward he stumbled, and to save himself from falling placed a hand against the wall. The next moment he leapt backwards with a yell. His hand and arm had gone clean through the filmy shape.
"I'm Miss Coralie Rothvelt," she added, and then how she sparkled in the dark as she said, "I see you remember me.""The hatchways were covered with gratings to admit of a free circulation of air, and they were so firmly fastened that the coolies could not disturb them. Several men were on deck when the trouble began, and one of them tried to get through the grating to join his companions. He managed to squeeze his body through the opening, and then discovered too late that he had a fall of nearly thirty feet before him, as the hatch of the lower deck was open. He struggled a moment, then dropped to the lower hold, and was killed by the fall.
For the life of him Bruce could not say. It was absurd to suppose that by some mistake the Bank of England had issued two sets of notes of the same series of numbers. There was no mistake about the murdered man's letter either.
"I fancy you could," said Lawrence.For loading and unloading carts and waggons, the convenience of the old outside sling is well known; it is also a well-attested fact that accidents rarely happen with sling hoists, although they appear to be less safe than running platforms or lifts. As a general rule, the most dangerous machinery for handling or raising material is that which pretends to dispense with the care and vigilance of attendants, and the safest machinery that which enforces such attention. The condition which leads to danger in hoisting machinery is, that the power employed is opposed to the force of gravity, and as the force of gravity is acting continually, it is always ready to take advantage of the least cessation in the opposing force employed, and thus drag away the weight for which the two forces are contending; as a weight when under the influence of gravity is moved  at an accelerated velocity, if gravity becomes the master, the result is generally a serious accident. Lifting may be considered a case wherein the contrivances of man are brought to bear in overcoming or opposing a natural force; the imperfect force of the machinery is liable to accident or interruption, but gravity never fails to act. Acting on every piece of matter in proportion to its weight must be some force opposing and equal to that of gravity; for example, a piece of iron lying on a bench is opposed by the bench and held in resistance to gravity, and to move this piece of iron we have to substitute some opposing force, like that of the hands or lifting mechanism, to overcome gravity.
Shaping machines as machine tools occupy a middle place between planing and slotting machines; their movements correspond more to those of slotting machines, while the operation of the tools is the same as in planing. Some of the advantages of shaping over planing machines for certain kinds of work are, because of the greater facilities afforded for presenting and holding small pieces, or those of irregular shape; the supports or tables having both vertical and horizontal faces to which pieces may be fastened, and the convenience of the mechanism for adjusting and feeding tools."But how did you know that I had it?"
