Show Science and Industry The stems of several different shrubs and trees are used by the natives of Santo Domingo In the nature na-ture of a toothbrush, or as what the natives call a "chew stick." Among others the stems of the orange, the lemon, and the membrlllo or quince tree are used on account of the agreeable agree-able flavor of these woods. But the most commonly used is a pla it ordl-i.arily ordl-i.arily called "guano" which is probably prob-ably the same as the one called in Spanish "palma de guano" with the scientific name Trynax argentca. "Guano" grows in large quantities in the vicinity of Bani and Sa,n Chlsto-bal. Chlsto-bal. The natives use the green stem, the end of which they chew up and use in the nature of a toothbrush. It is said that the natives of Porto Rico, Jamaica, and other West Indian countries coun-tries allow the chew sticks to become cry before using them. Sunlight is so important to life that it is little wcider tho sun worshipers wor-shipers prevailed In primitive days. Plant a potato in your cellar, and if there is a little light the potato will pprout and try to grow. Surround it with the best fertilizer, water it, and do the best you can for it except that ou keep it in the dark, and it cannot can-not digest and grow. See how slender i rid' pale It Is! The process of digestion, di-gestion, the great function of assimilation, assim-ilation, cannot go on without sunshine. sun-shine. Nature's laws are the same In the animal world. It is just as true that the only girls with red cheeks and sweet breaths, the only girls who become fully ripe and sweet, are those who baptize themselves fully in glorious sunshine. The many pale Mrls who are to be seen with a bloodless, blood-less, half baked sort of face, whose ualk, whose voice, and whose whole expression Is devoid of spirit, are not half ripe. The suggestion that there are air-quakes, air-quakes, due to explosions of meteorites, meteor-ites, and quite independent of earthquakes earth-quakes and volcanoes, comes from no less an authority than W. F. - Denning, Den-ning, the astronomer. That such explosions ex-plosions are sometimes audible Is well known. Prof. W. M. Foote has Just recorded that a large meteorite falling near Holbrook, Ariz., at 0:80 p. m. on July IT. 1912, broke up with a loud r.olse that lasted half a minute or wore, und scattered over a stretch of three miles of sandy desert, more than 14,000 of the fragments of a total weight of nearly 500 pounds having 1 een picked up and preserved. The exploding bodies, of course, are not always- seen. Other similar Instances have been recorded, a.nd two meteorite meteor-ite explosions noted In 1877 on Nov. fl and 28 were estimated to have created air disturbances more than a hundred times as lolent ns a loud peal of thunder. The peculiar agricultural limitations limita-tions of Japan were brought out in I a recent paper by Miba E. C. Semple I 1o the Royal Geographical society ol England. With an equable Islant climate and food from both land and sea, the conditions favored the de--velopment of early civilization, but the lack of new area to cultivate for' the growing population soon brought the stage of intensive agriculture. Production within the Islaad area has been handicapped. Forests and barren bar-ren land make cultivation rare above 3,300 feet, and the arable land of Japan is only 14.37 per cent of the total area, which Is a lower percentage percent-age than is known elsewhere except in Finland, Sweden, and Norway sparsely populated countries. The. staple crop, rice, Is confined to the vicinity of rivers and streams. The available soil is not of fertile kind, and low efficiency is promoted by the practical absence of stock raising. A few attempts to reclaim barren and ill watered wastes are being made by wealthier 'farmers or companies. Dr. Leo Frobenius, chief of the German Central African explorat'on epedlMon, who asserts that he has located the exact site of the lost Atlantis, has just expounded his views and the results of his travels before the kaiser. The kaiser is much Interested in the trophies that Frobenius Fro-benius obtained In support of his Atlantis views, particularly the collection col-lection of terra cottas. "Uno sees that these never were made by negroes," was his majesty's terse comment. , The rnperor also thought the terra cottas were portraits, as every head is different. dif-ferent. Dr. Frobe .ilus exhibited the pVitojraph of a Mjt.antinc Imperial -89 castle which he had discos cred in the MM heart o Africa.
