We cannot see that the court below erred in the point decided. The contract, which is Sought to be enforced, appears to be illegal under the laws of the United States and the post office regulations made under those laws.

See Revised Stat. U. S., 3737, 3709, 3963 ; Post-office Reg., 1877, p. 146; Adver. for contr., P. M. Gen’l., of 1876, p. 51.

The contract on which the suit depends being illegal, no court will enforce it.

Judgment affirmed.
