the New World." In 1850 sixteen millions sterling of specie annually did less for the wants of the world than ten millions had done in 1810, and much less than two mill- ions had done nearly three centuries pre- viously, in the reign of Queen Elizabeth. " Whenever the supply of money becomes stationary in the civilized world, or in a progressive community, prices begin to fall, owing to the steady increase of population and monetary requirements. Thus, . . . during the silver age, although the annual production of the precious metals increased continuously throughout three hundred years well-nigh doubling in each succes- sive century the monetary wants of the world increased quite as fast, and ere long began to outstrip the growth of the mone- tary supply." A careful analysis of the statistics of coinage and other uses, and of the supply of the precious metals, based upon the reports of the Director of the United States Mint, shows that "the cur- rent requirements for coinage of themselves exceed the total annual supply of the pre- cious metals by four millions sterling, while the consumption in the arts amounts to nine- teen millions indicating a reduction, or at least an inadequate supply, of metallic mon- ey to the extent of twenty - three millions annually." The disastrous effects of a mon- etary dearth are extensive. It affects not only current trade, but real property, or fixed wealth of all kinds. The value of money is rising, and consequently the sale value of all other commodities is falling. Even the moneyed class lose also, owing to the low rate of interest and the lack of re- munerative kinds of investment; but agri- culture is most affected by a change in the value of the circulating medium, because such a change comes upon it with di- rect and unbroken force. Thus, the mis- chief works round the whole community, or indeed the civilized world. No human power can prevent the embarrassment aris- ing from an inadequate production of the precious metals. "But, fortunately, the source of our present difficulties is no longer the mystery that it was, even to statesmen in former times. The fact that nowadays it can be traced to its fundamental causes constitutes the best hope amid our present difficulties."

Is Tea-drinking salntary? The Dean of Bangor has charged tea-drinking with destroying the calmness of the nerves, mak- ing people uneasy and irritable, and acting as a dangerous revolutionary force. Some medical men, including American doctors

and Dr. Richardson,

agree with him;


Dr. Gordon Stables has pronounced tea "the drink of pleasure and health," and has ex- pressed the opinion that it ought to be the national drink of England. The general current of public opinion and practice ap- pears to be favorable to the latter view. In the British army, says the "Pall Mall Gazette," the use of tea is slowly but surely supplanting the use of grog. The soldiers who captured Tel-el-Kebir dr ank nothing but tea. It was served out to them three times a day, and they found it most pleasant and invigorating on the march. Its use among athletes and others who perform physical feats is becoming more general. The use of alcohol and tobacco is universally con- demned in the various hand-books on train- ing, but the use of tea is always recom- mended. To the charge that tea-drinking stimulates revolutionary tendencies may be answered that the greatest tea-drinking na- tion in Asia, the Chinese, is the most con- servative, and that the Russians, the great- est tea-drinkers in Europe, are the most stolid of Western peoples. Of great men, Dr. Johnson described himself as "a hard- ened and shameless tea-drinker." Kant used to breakfast on a cup of tea and a pipe of tobacco, and to work on them for eight hours. De Quincey usually drank tea from eight o'clock at night till four o'clock in the morning. Buckle was a most fas- tidious tea-drinker. William Howitt regu- larly took tea and coffee, and found the greatest refreshment in both; and Mr. Glad- stone is one of the greatest tea-drinkers of the century.

Variation in Earthquake-Vibrations.

Professor Milne, of Tokio, Japan, making a seismic survey of the ground near bis house, placed similarly constructed and test- ed seismographs at different places, but in similar positions. The result of observing many earthquakes was that all the instru- ments, the positions of which would be in- cluded within a triangle, the sides of which
