New. T Type of Lake Freie ' ~The Ralleay and Siasine World gives lin the current number. the following -- | description af a new freight steamship, ! ' The Toiler, now being built in Eng: 'land for the 'Canadian canal and lake trade? which it sats will be a decided | 'innovation. It is simply a hull, with-/ 'ont any top hampe?, masts, or 'cven! funnels, as it will be operated by ine. 'ternal combilstion oil engines, -- the 'same as automobiles. It will be the! Hirst bout of the kind to be operated | 'the Great Lakes for* commercial! 'purposes, and will also be the first: | vessel in the canal carrying trade to! juse double propellers, which, it is 'elaimed, Will prove of great advantage in manoeuvering, The adoption of this type of boat ts! in line with the natural evolution of! the canal freighiter. With the short, season and high wages paid, shippers have been using all their ingenuity to get as much out of a given site ol ves- | sel as is possible, The lake tongage fe 'is divided into two classes, «the ig upper freighter-and the canal boat, ' while the latter is divided into two | types, the package freighter and the} i hulk carrier. The great increase in the | bulk shipments "of coal from Lakes {Krie and Ontario points to Montreal, | | the building of the Port Colborne cles} tvator and the elevators in Montreal, | together with the pulpwood trade,have of late tended to make the bulk! ' | freighter A-Mmost important .type, The | = 'continual struggle has been to get the} greatest possible deadweight on the limited draft. But) with the Limita-/ tions of the canals and locks, it is im-| he possible td increase the dimensions of, "gs | tito; so that any increase in dead-: R. weight must be taken out of the ma-! e, terial and equipment. The limit in| nt reduction, of weight of material tsed in construction has Tong been Fetched. | | i] ye e>m 2 kL is so-that-the--only method_ot increasing | e en carrying capacity was -by reducing the) -- ry weight of the propellinb machinery. i | im!
