“ The words, 'pay proper,' we see no reason to think are to be construed differently from the word 'pay.' The term means compensation, pensation, which may properly be described or designated as 'pay,' as distinguished from allowances, commutations for rations, or other methods of compensation, not specifically described as pay. ”

“ The term 'pay proper' used in the acts of May 26, 1900, and March 2, 1901, includes, in our opinion, the longevity pay under § 2162 as well as the sum named as pay under § 1261, the latter being the minimum sum for the grade. Every five years of service, under § 1262, up to a certain percentage of the yearly pay of the grade, as provided by law (§ 1263) entitles the officer to be paid 10 per centum of his yearly pay. ”

“ Under the language of the act of March 15, 1898, the Comptroller of the United States had held that the language used in that act showed that the compensation of enlisted men, upon which the per centum provided for was to be computed, was the minimum pay, not enlarged by any longevity pay to which the person was entitled. ”
