The first fall has a head of 350 feet, and operates five turbines of 500 horsepower each, direct-connected to low-tension alternators, while the second fall, of 680 feet, drives ten similar turbines with high-tension dynamos ; the two-phase system is used. The first fall gives 2,500 horse-power, which is all utilised for the production of carbide; the second fall gives 5,000 horse-power, and one M. Rossel describes a number of other plants, including that of Vernoya, with turbines of 4,500 horse-power, 900 of which is used for carbide ; Thusis, using 3,000 horse-power, with plant, disposing of 5,000 horse-power, and using 1,800 for carbide, etc. In the second part of his paper M. Rossel speaks of the raw’. material used. Limestone of very good quality is found in Switzerland, which gives lime of 99 per cent. purity, and containing no trace of © phosphoric acid. The carbide delivered to commerce is guaranteed to give4:8 cubic feet per lb., but generally it exceeds this by 2 to 5 per | cent. aust OIA oe Ethics of Lanterndom. ; By D. TURNER. Mx HAT nonsense! iiubbish!! Who 4 ever heard of such!!! Ah! but stay your exclamations and remember ‘“‘ There is an ethical side to all things.” And among the thousands of things are found ee music, sculpture, painting, astronomy, i physics, physiology, natural history, electricity, chemistry, photography. The arts and sciences generally, any one, all of them, together with others too numerous to detail, play important parts in the arena of lanterndom. | Rob any main factor, or science, or study, of the right of entrance to this arena, it becomes, as it were, outside the radius of advancement ; it loses part of its clothing, its progress is impeded, it is all but dead, its morale becomes a dead letter. could never happen. Lanterndom has built up and is still building, developed and is still developing, and perfecting all that is great, all that is grand, all that is noble, all that is good, all things worthy of the name of study, and in this year of grace, This robbery is but a surmise, it : way, did what I bid, some accompanying us for . kissed both of them. twelve furnaces of 250 horse-power ; the Nidau | 1900, few, if any, studies outside its curriculum. And it came about in this way. Our earliest recollections will no doubt bring to our minds associations of the old nursery at home with its toy cameleon top, its toy wheel of life, its toy kaleidoscope with its shifting crossings of green and gold, its toy camera obscura, its toy camera lucida, its optical marvels and delusions, and lots more. Then are attempted | the nursery literature, the fairy tales ever half of this energy is used for the same purpose. | foremost. What a wonderful chap “Jack, the giant-killer”’ was. What a little angel we thought the child-girl ‘‘ Cinderella.” Her wonderful godmother, too, who couldn’t have “Jack and the beanstalk,” the rapid growth of the latter, surprising the minds of thousands of the juvenile fraternity. Next came Grimm’s goblins, displaying to our mental vision all that was ghostly and ghoulish and demonlike, ” “ Gulliver’s Travels” were the most magnified dreams imaginable. The fables, too. Who doesn’t remember the fables? Fairy-like, perhaps, but cram full of truths, of solid hard facts of yesterday, to-day, and to-morrow. It was in the nursery, too, that the nurse-tutor gave the reading lesson, short and to the point. Two specially crop up in the memory analogous to our subject. First, Humphrey Davy working in a garret, inventing his safety lamp, which lamp was the means later of his name being inscribed on the historical scroll. Davy was puzzled—and he wouldn’t have done what he did if he hadn’t have been—and groaned ‘ Oh, that this were a magic lamp, and do as I bid it.” Again, an incident in the travels, adventures, and explorations of the bare-footed factory lad, afterwards Dr. Iuivingstone. ‘The tribes were most troublesome,” so read the nurse, ‘“ | knew not what to do to subdue their savagery, and did not want to use force, when suddenly, as if by witchcraft, I thought of my magic lantern, and hastened to unpack. In a very short time the noises ceased. Men, women, and children were held spell-bound. They were captivated, I had won, and before many more | hours had passed they who had thirsted for my blood and the blood of my followers worshipped me now as their god. They helped me in every some days.” So the nursery was—andis— responsible for the first introduction to lanterndom. The first charm was there set, the first steps of interest were there taken, interests that were foundations of morals that were clutched at.
