Japan, on the terrestrial globe, lies furthest away in that direction beyond the Far West of America, and beyond the wide Pacific. The Japanese structure has a simple and solid aspect, resembling the portal of a half-fortified mansion, with massive timber frames at the sides; but it is adorned with two handsome porcelain fountains, and each of these is designed to represent the stump of a tree supporting a shell into which the water is poured from a large flower. Before entering the porch a large map of Japan and a plan of the city of Tokio are seen displayed on the walls to right and left.--_Illustrated London News._ * * * * * =Machinery for New York State Capitol Building.= The Buckeye Engine Company of this city have been awarded the contract for a pair of condensing engines, cylinders 14 inches diameter, stroke 28 inches, for the State Capitol Building at Albany, New York. The engines will be of the company's usual horizontal type with automatic cut off, and will be elaborately finished. * * * * * =The Explosiveness of Flour.= Professors Peck and Peckham, of the University of Minnesota, have been making an extensive series of experiments to determine the cause of the recent flour mill explosion at Minneapolis. The substances tested were coarse and fine bran, material from stone grinding wheat; wheat dust, from wheat dust house; middlings, general mill dust, dust from middlings machines, dust from flour dust house (from stones), and flour. When thrown in a body on a light, all these substances put the light out. Blown by a bellows into the air surrounding a gas flame, the following results were obtained: Coarse bran would not burn. Fine bran and flour dust burn quickly, with considerable blaze. Middlings burn quicker, but with less flame. All the other substances burn very quickly, very much like gunpowder. In all these cases there was a space around the flash where the dust was not thick enough to ignite from particle to particle; hence it remained in the air after the explosion. Flour dust, flour middlings, etc., when mixed with air, thick enough to ignite from particle to particle, and separated so that each particle is surrounded by air, will unite with the oxygen in the air, producing a gas at high temperature, which requires an additional space, hence the bursting. There is no gas which comes from flour or middlings that is an explosive; it is the direct combination with the air that produces gas, requiring additional space. Powerful electric sparks from the electric machine and from the Leyden jar were passed through the air filled with dust of the different kinds, but without an explosion in any case. A platinum wire kept at a white heat by a galvanic battery would not produce an explosion. The dust would collect upon it and char to black coals, but would not blaze nor explode.
