A Hungarian gentlemen has, we are told, constructed a railway five miles in length on a mountain in the heart of Hungary. A remarkable peculiarity is the total absence of all permanent way. Square beams of oak 3 inches high and 14 inches broad are laid on the ground, and only at rare intervals, where the great unevenness of the ground abso lutely requires it, cross sleepers are laid under them. Each of these longi tudinal beams has a length of 18ft, and on the two edges* of the beams are tha rails, which are only 2in. broad, and so thin that they weigh about lib. per foot. These beams and rails may be taken up at any moment, and the railway tlius relaiil whenever it is required The trucks run on two pairs of wheels Sin. in diameter; the bodies of ihe trucks are about three times the width of the rails, and are placed so low on the wheels that they have just room to pa*a over them. The arrangement of the weight and the system of breaks are said to be so perfect that the train may be stopped when on a gradient of one in seven, and going at the rate of twenty or thirty miles an hour, within six to eight jards. The five miles cost 10,000 dollars, and after the experience now gained the work may be done for about 1,000 dollars per mile.—Scientific American,

The organ of the Zurich Society of Natural iiiVtory publishes a curioua account of the travels* of the glacier of Mount Jtiosa during the last sixty yearn. For fiftv years it steadily and surely approached the town of Zeraiatt, mov ing at the rate of about three feet a week during the spring months. Its way was through pastures and grain-fields, over which it passed like a devouring pestilence. Its approach was heralded by great boulders, which it kept con stantly moving before it. Seiious ap prehensions were at one timeentertained for the safety of the town, which lay directly in its track.
