Under the old postal arrangement, the salary of postmasters of the principal cities was limited to $2000. This compensation was derived from a commission out of their receipts, which could not exceed the amount named. This would appear at first as small pay for such an important position,—more particularly as under the administration of Postmaster Blair the salary was raised to $4000: yet there is not a postmaster but would willingly go back to the old system. Under the former provision of the postal law postmasters were allowed the amount arising from the rent of letter-boxes in their respective offices as a perquisite, and also certain other matters, which shrewd men knew well how to place under this head. During the existence of this system the desire for the office far exceeded that which was and is likely to be manifested under the latter, inasmuch as $4000 per annum and _no perquisites_ is scarcely a desirable position for an ambitious and popular politician. Many a business-man, outside of the political ring, would consider it quite sufficient, however: _business-men are not cormorants_. It is true, even under the old law, by an act passed March 3, 1847, the rent of boxes to be credited to the postmaster was limited, restricting the amount so received to $2000,—consequently limiting his salary to $4000: for all over and above that amount he had to account to the department. Under some administrations postmasters became rich, whether by husbanding their actual income or the perquisites are questions simply of conjecture. _THE PENNY POST._
