Our Current Weights and Measures.—The absurdities of our present no-system of weights and measures surpass belief: they have their parallel in the absurdities of our present no-system of "orthography," but hardly anywhere else. The question of reducing to rule the current English orthography is now receiving attention, but the prospects of anything being done are gloomy enough. So, too, we hear occasionally of the necessity of reforming our weights and measures, but as yet no real progress has been made in any of the English-speaking countries. Our excellent contemporary, the Engineering and Mining Journal, in the course of an article favoring the adoption of the "metrical" system, gives the following apt illustration of the deplorable multiplicity of standard tons now in use:

"In a copper-works ore is measured and paid for by the (tribute) ton of 2,352 pounds, from the mine through the mill, till it comes out of the jigs, when suddenly it is transformed into a ton of 2,240 pounds (the difference, perhaps, going out in the tailings), which is the ton of the roasting and smelting furnaces and of the teamsters. This continues till the copper is sold or carried over some roads, when the ton shrinks again and becomes 2,000 pounds. At the iron-works there are still more tons, different from these, and on the railroads one will report the coal carried in tons of 2,240 pounds, and another connecting road uses
