Nevertheless, it is gratifying to record that, in addition to the slight increase al ready mentioned, 77,306 tons of shipping were commenced in this country during the last three months, this figure exceeding by more than 5,000 tons that of the tonnage commenced during the'] whole of the year 1932.

In the "mercantile marine, how ever, the water-tube boiler has made very great hoadway, partly because boiler weights, relatively high as they may be, generally con- stitute but a small fraction of the total displacement. Nevertheless, in an instructive paper read some twenty years ago before the Institu- tion of Engineers and Shipbuilders The vessels under construction in in Scotland, Mr. E. M. Speakman British shipyards at the close of maintained that there were certain the quarter under review number services in which the adoption of ed 88; of these, 47 were steamships, water-tube boilers would prove 15 were matorships, and six were highly advantageous.

Much, however, has happened during the last twenty years, and in a paper by Engineer Rear-Ad- miral W. M. Whaymar and Major W. Grogaon, M. Inst.C.E. read on February 24 before the North-East Coast Institution of Engineers and Shipbuilders, the authors put for ward a reasoned plea for installing the water-tube boiler, in tramp steamers.
Foreign Countɣles.
All the principal foreign ship.. building countries, with the excap- tion of Sweden, have reduced to- tals. France retains first place with the greatest tonnage in hand, namely, 97,489; Sweden moves up. to 'second place with the increased total of 82,332 tons; Italy is third with 58,098 tons; Japan fourth with 53,570 tons; and Germany fifth with 32,585 tons. The vessels under construction in the world's shipyards at the end of March in- cluded seven motorships, each of between 8,000 tons and 10,000 tons, seven motorships of between 10,000 and 20,000 tons each, and three steamers each of 20,000 tons and upwards..?
