These latter qualities or principles do not have asdirect a bearing upon the character of the framing as the neces-sary requirements of reliability and the economics of productionand operation, but the real merit of any design and the extremecare manifested in its completion will be shown by the disposi-;ion of the framing so as to secure a maximum of these desirableends with a minimum of material and productive labor, and theutilization of each detail of the design to perform a multiplicity. fig. 4. of functions wherever possible, with each proportioned to itsrequired service. The time element involved in the designing ofsuch equipment, by the variation of conditions in the arrange-ment and framing in order to note to just what degree the prod-uct can be simplified, is well repaid in the final result. The cen-tralization of functions in one unit to eliminate numerous sepa-rate parts should, however, be solved with a regard for thefacility for repairs. Other conditions being equal, the simplestdesign is the best and displays the best thought. Summary.—The car shortage is now being felt in passengerservice as well as freight and the necessity for large orders in the immediate future, especially those for tunnel operation, war-rants the building of equipment of the highest class. Since 1902American designers have been developing those ideas in steelequipment which, though net new nor brought before the publicnow for the first time, are still of the highest value and worth.
