But Austria is not beery alone. She has fine exhibits in horology, electric and pneumatic telegraphy, and in tools, grain-mills, gang-saw mills, and machines for making paper bags. More important, as some might say, are the admirable locomotives and stationary engines, cars, fire-engines, and her collection of iron-work, in which are exhibited cast-iron car-wheels, made by Ganz & Co. of Buda-Pesth, which have been in use twenty-one years and have run without apparent severe injury a distance of 549,108 kilomètres, or nearly 280,700 miles.
The beet-root sugar interest is becoming very important in Austria, but the evidences of the Exhibition indicate that the diffusion-process holds better credit there than in France, where it is not approved of. The rotative apparatus shown is an immense affair, with a series of eight tall tanks arranged on a circular carriage and rotating on a vertical axis, so as to bring each in turn to the charging and discharging positions. Each tank has its own system of pumps. Beet-root is difficult to exploit for various reasons, chemical and other. Like the vine, it is particular in its nutriment, requires great skill to remove extraneous substances, and can hardly be handled by the French system without a set of machinery costing about eighty thousand dollars.
From Austria to Spain is but a step, but it is not productive of much information in the matter we have in hand. A beaming-machine for cotton warps, red, white and yellow, stands solitary in its section, and next to it is a model of a _cirque de taureau_, composed of nineteen thousand pieces of tin laboriously put together without solder, as if that were a merit, and stated to be the work of two years. In the arena the wooden bull regards with indifference two mounted cavaliers and seven footmen in various provoking attitudes. Near by are various machines and presses for the treatment of grapes and olives, grinders and presses in variety, a sugar-cane press and a turbine. Barcelona would seem to be the most enterprising of Spanish cities. Several exemplifications of the excellent iron of Catalonia and Biscay suggest the direction in which Spain has taken its most important industrial start of late years. An admirable model of the quay of the copper-mining company of the Rio Tinto is another evidence in the same line which the maps, plans and ores amply corroborate.
