The people develop a dliincllno-Uo dliincllno-Uo to work, nnd become strangers to ambition of any description. Ou homogeneous irons and low-carbon steels, not subjected to heat-treatment, It appears that each one per cent, of picked added, up to five per cent., causes an increase of about 5.00U pounds elastic limit and 4,000 pounds tensile strength, Mnlne stand second among the state In the daily output of pulp and paper. Including the product of th three planti now building It is estimated that the dally output will be 2.1G5 tons ami hc total investment In this elan, (if property will be $30,000,000. Aluminium stoppers for bottles arq now being made nt the rate of beveral thousand pounds u week. Tlie blanks are cut from sheet ineinl and, nfter shaping, rubber gaskets are forced over them. Surhtoppers hae retained tho gas of eiTerescent fluids for four jeers. Artificial silks are made of wood fiber, reduced to cellulose by the action pf acids. This is dissolved to n glue-like glue-like consistency, forced through holes In glass and drawn out into threads which dry and harden in the nlr just 8 those of the silk worm or spider do. The Slmplon tunnel, which is now be-Ing be-Ing bored, and which will be the second sec-ond connecting link between Switzerland Switzer-land and Italy, is to be tho largest tun-nel tun-nel In tho world.
