The Act, in paragraph (7) of section 7, exempts from its provisions
``any contract with the Post Office Department, [now the U.S. Postal
Service], the principal purpose of which is the operation of postal
contract stations.'' The exemption is limited to postal service
contracts having the operation of such stations as their principal
purpose. A provision of the legislation which would also have exempted
contracts with the U.S. Postal Service having as their principal purpose
the transportation, handling, or delivery of the mails was eliminated
from the bill during its consideration by the House Committee on
Education and Labor (H. Rept. 948, 89th Cong., 1st sess., p. 1).
