Westinehouse ACHIEVEMENT & OPPORTUNITY MARCH, '1925 3 General Motors Building Detroit, Michigan ALBERT F. KAHN, Architect "In 'Cferms of Drawn by Hugh Ferriss the Colossal" THE co-ordination of commercial strength, architectural vision and engineer- ing skill which created this titanic quadruple office building represents the motive and creative force which has turned the eyes of the world toward this type of American architecture. This, the largest office building in the world, possesses fundamentally magnificent largeness in irs conception, and a clean-cut directness in its ex- ecution which place ir among the most significant of American buildings. With such existing structural achievements no architectural future is impos- sible, no project too vast or too complex to come readily to our imagination. Certainly modern i~vention-modern 'engineering skill -and organization, will prove more than equal to the demands of the architecture of the future. o TIS ELEVATOR COMPANY Offices in all principal Cities of the World 4 THE CO-OPERATIVE ENGINEER GATHERING·LINE HEADERS AT PLANT NO.9 OF CHESTNUT AND SMITH CORPORATION, KIEFER,OKLAHOMA KEEPING FAITH WITH THE OIL INDUSTRY'S FAITH IN CRANE Experienced engineers in oil fields and Crane engineers regard this confidence as refineries place their confidence in the a definite responsibility.
