6 ½” x 9” black and white glossy photograph pasted on 8 ½” x 11” sheet of paper (WJE written upper and lower right corners). (typed caption) Chatelard Aqueduct, Canton Valais, Switzerland, 1925. Robert Maillart, engineer. 100-foot span. The structure is hybrid, for the arch springs conventionally from its abutments, then merges with the box girder that carries the water. This fusion of two seemingly incompatible forms is curiously successful.
