The Chautauqua University recognizes the importance of this matter. Its aim is to help, to guide, and to instruct, and it is now, through the liberality of its friends, able to help, guide and instruct all who wish to learn something of the art of producing food and saving money. It sees hundreds of boys and girls totally ignorant of these common things. It sees young people wondering what they shall do, perplexed and worried over this question of earning a living, and discouraged at the high cost of living, when a part of their living is going to waste beneath their feet. The Chautauqua Town and Country Club was formed to help those who wish to help themselves. It aims to show by simple lessons how to raise plants of all kinds, how to care for animals, how to take care of your garden so that it will be a source of pleasure and profit. Half a thousand people have already joined the club and are now at work in good earnest. Should you wish to know more about it, write to Miss K. F. Kimball, Plainfield, N. J.
Of which so much has been said in these pages, continues to be discussed with increasing interest by astronomers of both hemispheres, who every day supply their quota of new ideas as the result of their investigations. In THE CHAUTAUQUAN for March, 1884, the statement was made that “it has already been demonstrated that the colored prominences may be examined at any time when the sun can be seen; and it is believed that Mr. Huggins has accomplished the difficult feat of photographing the corona, so that it, too, may be scrutinized _at leisure_.” In the April number of the _Nineteenth Century_, we find a very interesting account by Mr. Huggins himself, of his operations in this line. As yet the experiments have not been in all respects satisfactory; but so much has been done as to leave no doubt of the final result. As Mr. H. tells us, the great obstacle to overcome is the immense curtain of air, which “hangs” between us and the sun, and absorbs some forty per cent. of the sun’s light (and heat). This absorption renders our atmosphere as light at least as the sun’s corona, and makes it as difficult of observation as a lesser light placed behind a greater. The same atmosphere being as bright, or brighter, than the stars, prevents our seeing the latter in daylight. During an eclipse of the sun, the shadow of the moon affords us a long, funnel shaped tube through this great air curtain (which may be forty, or one hundred, or more miles in thickness) and we are enabled through it to see the sun’s corona. But “on an average, once in two years this curtain of light is lifted for from _three_ to _six_ minutes”—a very contracted period in which to obtain a knowledge of a phenomenon that we know is constantly changing. If we had a Joshua, who could command sun, moon and earth to stand still for the space of a few hours even, we might discover what we so much wish to know, what is this corona. Or, if we could go beyond this atmosphere of ours—place it between us and the earth, we might do without a Joshua. But we can not get outside. Then the next best thing is to get as nearly outside as possible. Dr. Copeland tried this by climbing an elevation of 12,400 feet. Prof. Langley ascended Mt. Etna, and on Mt. Whitney ascended to the height of 15,000 feet; but at these heights the curtain was still too heavy, and no view of the corona was obtained; or, as Prof. Langley expressed it, he “met with entire non-success.” From reports in regard to observations made in Egypt of the total eclipse of 1882, Mr. Huggins conceived the idea of making a photographic plate so sensitive that it would distinguish differences imperceptible to the eye, and on this plate take a picture of the corona, and then examine it as one would the “photo” of a friend, and mark its peculiarities. He made his first experiment in 1882, and as a result “there seemed to be good ground to hope that the corona had really been obtained upon the plates.” In 1883, a second attempt, under more favorable circumstances was made, and “images of the sun exquisitely defined, and free from all sensible trace of instrumental imperfection were obtained.” On the 6th of May of the same year (1883) a total eclipse of the sun occurred at Caroline Islands, and was there photographed by Messrs. Lawrence and Woods, photographers of the Royal Society; and on a comparison of these photographs of the sun’s corona during an eclipse with his own taken both before and after the time of the eclipse (which was not visible to Mr. H.), he had the satisfaction of seeing so strong a resemblance as to convince him that he had photographed the corona without an eclipse.
