Science needed two thousand years to disentangle the earth's orbital movement from the revolutions of the other planets, and the incomparably more arduous problem of distinguishing the solar share in the confused multitude of stellar displacements first presented itself as possibly tractable a little more than a century ago. In the lack for it as yet of a definite solution there is, then, no... more...

Editor Prairie Farmer—I write you in regard to the corn question. I would like to know if angle-worms damage corn. Eight years ago I came to the conclusion that I could raise double the number of bushels of corn that I was then raising. I then commenced experimenting on a small scale. I succeeded very well for the first three or four years. I got so that I could raise over ninety bushels per acre. In... more...

DATES AND THE DATE PALM. Even those whose knowledge of the customs of the Orient extends no further than a recollection of the contents of that time-honored story book, the "Arabian Nights," are doubtless aware that, since time immemorial, the date has been the chief food staple of the desert-dwellers of the East. The "handful of dates and gourd of water" form the typical meal and daily... more...

THE FRENCH SCIENTIFIC STATION AT CAPE HORN. In 1875 Lieutenant Weyprecht of the Austrian navy called the attention of scientific men to the desirability of having an organized and continual system of hourly meteorological and magnetic observations around the poles. In 1879 the first conference of what was termed the International Polar Congress was held at Hamburg. Delegates from eight nations were... more...

batalões turned from the open waters of the lower Tapajos River into the igarapé, the lily-smothered shallows that often mark an Indian settlement in the jungles of Brazil. One of the two half-breed rubber-gatherers suddenly stopped his batalõe by thrusting a paddle against a giant clump of lilies. In a corruption of the Tupi dialect, he called over to the white man occupying the other frail craft.... more...

A huge agave, or century plant, is now blooming at Auburn, N.Y. A few days ago the great plant became tinged with a delicate yellowish-white color, as its 4,000 buds began to develop into the full-blown flowers, whose penetrating fragrance, not unlike that of the pond lily, now attracts swarms of bees and other insects. The plant was purchased in 1837 by the owner, and was then twelve years old. For... more...

An officer of the Special Patrol Service dropped in to see me the other day. He was a young fellow, very sure of himself, and very kindly towards an old man. He was doing a monograph, he said, for his own amusement, upon the early forms of our present offensive and defensive weapons. Could I tell him about the first Deuber spheres and the earlier disintegrator rays and the crude atomic bombs we tried... more...

MR. E. H. PLUMACHER, U. S. Consul at Maracaibo, sends to the State Department the following information touching the wealth of coal and petroleum probable in Venezuela: The asphalt mines and petroleum fountains are most abundant in that part of the country lying between the River Zulia and the River Catatumbo, and the Cordilleras. The wonderful sand-bank is about seven kilometers from the confluence of... more...

THE TEMPLE ON THE ACROPOLIS BURNT BYTHE PERSIANS. The excavations conducted by the Greek Archæological Society at Athens from 1883 to 1889 have laid bare the entire surface of the Acropolis, and shed an unexpected light upon the early history of Attic art. Many questions which once seemed unanswerable are now definitively answered, and, on the other hand, many new questions have been raised. When, in... more...

ELECTRICAL LABORATORY FOR BEGINNERS. By GEO. M. HOPKINS. It is only when theory and practice, study and experiment, go hand in hand that any true progress is made in the sciences. A head full of theory is of little value without practice, and although the student may apply himself with all his energies for years, his time will, to a great extent, have been spent in vain, unless he by experiment rivets... more...
