For many years this fact has beenuniversally recognized in Europe, but in this country, with afew notable exceptions, of which the locomotive here consid-ered is one of the best examples, it has not received the atten-tion which it unquestionably deserves. Crane Hooks, depending from large traveling cranes inmachine shops, ought to be painted white, so as to be easilyseen. With this improvement in visibility workmen will beless likely to run against a hook or to be struck by one whichis moving. This point is brought out in National SafetyNews No. ^ A SELF-CLEARING HOPPER CAR BUILT EXCLU-SIVELY FOR GRAIN SERVICE In the construction of freight cars there is apparently atendency to adapt them to carrying a wide variety of is therefore interesting to note that the Canadian Pacifichas recently built a large capacity hopper car which is de-signed to handle but one commodity, grain. This car wasconstructed to determine by actual service test the net ad-vantages to be obtained from a grain-tight self-clearing carof tonnage capacity, as compared to standard boxcars of ordinarj- capacity. The limiting tonnage adopted as the basis of the design The car is all-steel, with the exception of the runningboard and the ridge on top of the center sill. The generaldesign is practically the same as is commonly used for coalcars of equal capacity, except that this car is built with asteel roof. The roof is provided with three hatch openingson each side of the running board, which are lo
