COFFEE. The discovery of coffee, according to the Oriental writers, took place towards the close of the thirteenth century; and, like most other discoveries of importance, it is attributed to chance. An Arab chief, the Scheik Omar, was flying from the pursuit of his own tribe. Having, with a small body of his adherents, taken refuge in the mountainous part of the province of _Yemen_, all ordinary means of sustenance failed them. In his extremity, perceiving a coffee-bush, the famishing chief essayed to gnaw the berries; but finding them too hard for mastication, he hit upon the expedient of boiling them――drank the decoction――found himself not only refreshed but invigorated both in mind and body; and from him the virtue of the precious berry afterwards became famous throughout the world. But with all its claims to notice, it required upwards of two hundred years for coffee to make its way to general appreciation. Like a prophet in his own village, it long remained slighted and neglected by its own native land. Three centuries elapsed from the date of its first discovery before the use of coffee, as a beverage, was generally adopted in the neighboring state of Egypt and in Turkey; whilst in Europe, as we all know, the introduction of the sober berry is, comparatively of but modern date. * * * * * MOTION. The common watch, it is said, beats or ticks 17,160 times an hour. This is 411,840 a day, 150,424,560 a year, allowing the year to be 365 days and six hours. Sometimes watches will run, with care, 100 years. In this case it would last to beat 15,042,456,000 times! The watch is made of hard metal; but I can tell you of a curious machine, which is made of something not near so hard as brass or steel――it is not much harder than the flesh of your arm――yet it will beat more than 5000 times an hour, 120,000 times a day, and 43,830,000 times a year. It will sometimes, though not often, last 100 years; and when it does, it beats 4,383,600,000 times. One might think this last machine, soft as it is, would wear out sooner than the other; but it does not. I will tell you one thing more. You have this little machine about you. You need not feel in your pocket, for it is not there. It is in your body, you can feel it beat; it is――your heart! * * * * *
