Occasionally the joints thus formed are " supported " on a sleeper, as was the practice in the early days of railway construction, but they are generally " suspended " between two sleepers, which are set rather more closely together than at other points in the rail.
At one end of each rail the flange spread out to form a foot which rested on a cross sleeper, being secured to the latter by a spike passing through a central hole, and above this foot the rail was so shaped as to form a socket into which was fitted the end of the next rail.
Each length was thus fastened to a sleeper at one end, while at the other it was socketed into the end of its fellow.
In that most largely used, known as " creosoting," dead oil of tar, to the amount of some 3 gallons per sleeper, is forced into the wood under pressure, or is sucked in by vacuum, both the timber and the oil being heated.
Sometimes a strip of felt is interposed between the chair and the sleeper, and sometimes a serrated surface is prepared on the sleeper for the chair which is forced into its seat by hydraulic pressure.
The mere immobility of the body was sufficient to show that its state was not identical with that of waking; when, in addition, the sleeper awoke to give an account of visits to distant lands, from which, as modern psychical investigations suggest, he may even have brought back veridical details, the conclusion must have been irresistible that in sleep something journeyed forth, which was not the body.
Dreams are sometimes explained by savages as journeys performed by the sleeper, sometimes as visits paid by other persons, by animals or objects to him; hallucinations, possibly more frequent in the lower stages of culture, must have contributed to fortify this interpretation, and the animistic theory in general.
The Bororos of Brazil fancy that in that shape the soul of a sleeper passes out of the body during night-time, returning to him at his awakening.
It is regarded by many savage peoples as highly dangerous to arouse a sleeper suddenly, as his soul may not have time to return.
Still more dangerous is it to move a sleeper, for the soul on its return might not be able to find the body.
Epicureanism generally was content to affirm that whatever we effectively feel in consciousness is real; in which sense they allow reality to the fancies of the insane, the dreams of a sleeper, and those feelings by which we imagine the existence of beings of perfect blessedness and endless life.
The mummy thus prepared was then laid on its side like a sleeper, the head supported by a head-rest, in a sarcophagus of wood or stone.
The list of his works of fiction includes The Stolen Bacillus and other Stories (1895), The Wonderful Visit (1895), The Island of Doctor Moreau (1896), The Plattner Story and Others (1897), When the Sleeper Wakes (1899), The First Men in the Moon (1901), The Food of the Gods (1904), In the Days of the Comet (1906), The War in the Air (1908), Anne Veronica (1909), The History of Mr Polly (191 0).
And when they run over a man that is walking in his sleep, a supernumerary sleeper in the wrong position, and wake him up, they suddenly stop the cars, and make a hue and cry about it, as if this were an exception.
Purposes: they diminish the wear of the sleeper under the rail by providing a larger bearing surface, and they help to support the spikes and so to keep the gauge.
