    LEWIS M. HAUPT v. THE UNITED STATES.
    [53 C. Cls., 591 ; 254 U. S., 272.]
    Judgment was rendered in favor of the United States in the court below. On appeal the judgment was affirmed, and the Supreme Court decided:
    Appellant sued to recover a large sum of money for the use, which he claimed, the Government had made of his patented improvements in dikes and breakwaters in the construction of jetties, which, with dredging, had resulted in rendering navigable to seagoing vessels the channel of Aransas Pass, on the coast of Texas. Held, that the appropriation acts evinced the willingness of Congress to expend money in testing his patented devices, but no intention to pay him until their usefulness should be proved, and that no promise of the Government to pay him for the use made could be reasonably implied.
   Mr. Justice Clark

delivered the opinion of the Supreme Court December 6, 1920.
