One curious thing about slate is that the layers are often twisted or wrinkled. This has been caused, partly at least, by their being thrust up when half hardened, so as to cause a sort of fold or crease. This was chiefly done by the still harder granite.
It is wonderful to think of the succession of plants and animals that slate has had to do with; it was in existence when the coal forests were forming, and it must have been trodden by the strange creatures of other strata, which are now extinct, but of which relics are dug up. Another remarkable fact is that the slate-beds have had wonderful ups and downs over and over again during the earth's changes—being at one time under a deep sea, at another lifted to form hills, as we frequently see them now.
FROST-BITTEN IN THE RED SEA.
A strange accident happened a few years ago on board a large steamer in the Red Sea.
One of the assistant-stewards had occasion to go to the ship's ice-room to fetch something which had been forgotten when the day's provisions were given out in the morning.
The man was not missed for some time, and, when search was made, the poor fellow was found nearly frozen to death. Some one had thoughtlessly slammed the door of the refrigerator, which could only be opened from the outside.
The prisoner had a terrible experience, and after doing what he could to attract attention, had sunk exhausted on the floor.
Fortunately, the head steward noticed that the key of the ice-room was missing, and this led to the man's discovery. If he had not been found till the following day, he would probably have been the first man to be frozen to death in one of the hottest parts of the world.
