Owners of steamers built of mild steel (says an exchange) are beginning to find out that when subjected to heat and the action of acids it deteriorates much more rapidly thaD iron. In some cases the inner plating of the double bottom in the range of the engine room has corroded through in a very short time. To meet this difficulty in numbers of new vessels, in the parts most likely to be affected, iron has been used. These are in addition to the inner plating of the double bottom, the frames and reverse frames in the coal bunkers. In a large cargo steamer now building, the difficulty has been met by a large increase of the thickness of the inner bottom plating. Not only has the reduction allowed for the use of steel instead of iron not been taken advantago of, but tho plating has been made thickec than it would bo required if of iron.
Recent dismissals from the mines at Broken Hill have swelled the ranks of the unemployed to such an extent that the matter is becoming as serious as ever.
