An Important Improvement In Gunnery.
Mr Krupp has introduced an important improvement whioh it is thought may lead to a material reduction in the expenditure on ordnance. All the heavy Krapp guns consist of a steel body strengthened by hoops, the 30| the centimeter guns having three tiers of hoops, 26" centimeter and 24 centimeter two, and the remainder one tier. The Interior of the body, drthe bdre'ofTfte goo,' being the part subjected co the greatest wear and tear, becomes rapidly worn out, and hitherto it has been found necessary after, at the very most, 1000 rounds have been fired, to melt up the whole gun, on account of the damaged condition of the bore, although the outer parts of the piece were practically as good and sound as ever. Since she construction of these outer hoops is very o >Btlf , the idea ocourred to one of the members of the firm that it might be possible to localise the melting operation, and this it has now been found possible to accomplish by treating tbe body of the piece with a cold producing preparation of oarbonlc add, whioh coatraots it to such an extent that the hoops, expanded at the name time by the application of heat, can be easily removed*
