British engineers interested in the building of rivetless shins'Have been verymuch encouraged by the satisfactory pepformanoes of the 500-ton ship Fullagar in her sea-going trials. There is not a rivet in this vessel from bow to stem; everything is electrically welded. The design was arranged so as to get the best results from electric welding with the least expenditure of time, labour, and materials. Where the plates were joined end on they were welded with a strap behind, and where the plates were lapped a weld was put on on both sides. In some-cases’a watertight joint was not required, and labour and material were saved hy a system of “broken welding.” Short lengths were welded with unwelded spaces between, giving a sufficiently good joint for all purposes except keeping out water. British pioneering work in electric welding is expected to receive a great impetus from the successful demonstration on the Fullagar, and future methods of ship construction are bo"nd to be radically affected. The new scheme to connect the Great Lakes of America with the ocean has been, estimated to cost something under £1,000,000, which would be shared between the Governments of Canada and the United States,
