Great Fountain, Enville to conceive. This, the large fountain, is on a level with the surface of the lake, and composed of five jets, the central one throwing a column of water 150 feet high; the supply being obtained from a large reservoir on the hill, to which it is first pumped by the united action of two engines, each of thirty horsepower.".

For de-icing purposes, Diamond opted for pneumatic boots on the wing's leading edges, bleed air for heating the inlets and ducts, and electric heating for the windshields and probes; in particular, Goodrich developed a considerably thinner de-icing system for the
