OIL CANS OF RATIONAL DESIGN - Just why certain peculiar forms of oil cans are used by rail-roads is a question, when we consider the severe service towhich they are subjected. Like many other things it is possiblydue to lack of study and consideration on the part of thosein charge of this work, or in the blind following of of the peculiar shapes in which they are made and the. An Oil Can Designed to Withstand Severe Service damage to which they are subjected is clearly shown in one ofthe photographs. The second photograph shows a new design which was intro-duced on the St. Louis & San Francisco a couple of yearsago and has given excellent service. The cars shown are of5 and 10 gal. capacity, made of No. 16 galvanized iron. These
