the action of tAe elemeatS, would produce bat one-third the lisp19e- ment AS when formed Of iron, thus proportlonately increasing their ton- mage or carrying capacity, or, with the same cargo as now enabling them to traverse waters comparatively shallow and with vastly greater speed.
 Tine present iron work of a'i our passenger and freight cars would piyr place to the stronger, han"- somcr, and safer meta! !--alunn'i D. with lWo-,hirds reduction It "e'oA. ' both for the saving in the wear and tear of the rails and track, and the expenditure of motive power for transportation. The locomotive alone might still require to be made of steel and iron, it> weight being needed Tor traclloh.
 For guns of every description the oreat .tenacity or tensile strength of aluminium would cause it at once to take the place of steel, bronze, or any other metal of like weight, whiie for ordnance of large caiiber. either for artillery uses on land or for the naval service. the ease with which such large guns could be handled would give the new metal decided preference the projectiles alone still requiring to be made of the weightier metals.
 The same distinctive conditions apply also in a marked degree to bridge. of every description, where the maximum tensile strength and indestructibility combined with ex- treme hexibility and liyhtness, con stitute the essential factors in these now mightiest engineering sttnct- ures of the world. Spans of enor- mOusIy greater lengths and breadth than any that now exist, would glad den the ambitious enterprise of our eminent mechanical and civil engin- eers. and inspire new projects hith- erto deemed impracticable, which would result in numberless advanta- ges in the progress of modern clvlll- zation including also in every class of bridges much greater safety to human life.
 In the details of domestic and gen eral use. it is impossible to ennamer- ate all the purposes to which the ne" metal would at once be applied witt increased utility. Take, for exam ple, the manufacture of bells O every description from the smalles to the largest zes,-in which de partment of manufacture all othel metals must at once go out of use no other metal compares with aluml mum for sonorous properties, either in intensity of sound or quality oi tone-while its superior levity would permit the hanging of large bells il much higher towers than at present and of two or three times the size o even the monster bell at Moscow, SC famed Tn history.
 For electrical purposes, such es pecially as in the case of suspended telegraph wires, all heavy metals would have to give way, since the conducting power of aluminium i' nearly equal to that of copper
 In every description also of cut lery and table service, such as steel plated, and silver wares, aluminium would at once be placed upon the throne and forever after be allowed to reign supreme in harmonious con- cert with the same beautiful and un. tarnishable metal wrought into every variety of cooking utensils and kitchen appliances, including stoves ranges, etc.
 Oil-tanks, as we'll as barrels, casks and wooden vessels generally, now universally employed for holling anc transporting wines, liquors, ect. would at once be supplanted by tho unavoidable aluminium, while ever bottles. carboys, demljohns, etc, O every variety, and for nearly every purpose, where transparency was mol an essential factor, would cease tt be made of glass, so easily broken and would take their places il beautifully polished vessels of alum mum.
 Time fails us to speak of the tubu lar aluminium masts and spars o yachts and other sailing craft, iighte than spruce and stronger than steel
