A GIFT FOR THE SMITHY.
Something was said last week of a German discovery for preserving wood in out-of-door situations. One of its alleged merits was that the preservative could be applied without moving the post, plank or what-not that needed this attention. A metal material has now been compounded which, it is said, enables iron to be welded without dismantling. It is called " Sif bronze " and has a melting point little more than half that of cast iron. This quality has a score of advantages. It can easily be melted under the blowpipe and " being deposited on the cast iron surface, it alloys with it and forms a very strong bond indeed." The invention is strongly urged upon the attention of village blacksmiths, a number of whom are now in possession of acetylene welding plant and by means of it are reviving the village smithy. " Sif bronze " will join with equal strength dissimilar metals. Those rural revivalists who wish to restore prosperity to the local smith can do no better service than help him to an acetylene-welding plant. The total cost is no more than £10 and in capable hands it should pay for itself within a month or two.
