delivered the opinion of the court.
This is a suit brought by the appellee Welles to establish a lien upon a debt of $6,830.85 due under a construction
*10
contract from the City of San Francisco, represented by the appellee Boyle, to the bankrupt, Metropolis Construction Company. The District Court approved the report of the referee against the claim and in favor of the appellant, but this decree was reversed by the Circuit Court of Appeals. 211 Fed. Rep. 561. 215 Fed. Rep. 81.
The contract provided that the contractor should keep the work under his personal control and should not'assign or sublet the whole or any part thereof without the consent of the Board of Public Works. It further declared that no subcontract should relieve the contractor of any *11 of his obligations and that he should not “either legally or equitably, .assign any of the moneys payable under this contract or his claim thereto unless with the like consent.” The city has made no objection to the assignment to the bank and the money now awaits the decision of this court as between the- claimant of the lien and the prior assignee.
There is a logical difficulty in putting another man into the relation of the covenantee to the covenantor, because the facts that give rise to the obligation are true only of the covenantee — a difficulty that has been met by the fiction of identity of person and in other ways not material here. Of course a covenantor is not to be held beyond his undertaking and he may make that as narrow as he likes.

v.
Belden Mining Co.,
The Circuit Court of Appeals relied largely upon
Burck
v.
Taylor,
The assignability of a debt incurred under a contract like the present sometimes is sustained on the ground that the provision against assignment is inserted only for the benefit of the city. Whether that form of expression is accurate or merely is an indirect recognition of the principle that we havé stated, hardly is material here. It is enough to say that we are of opinion that upon the facts stated the assignment was not absolutely void, that therefore the bank got'a title prior to that of Welles and con
*13
sequently that the decree must be reversed. See
Hobbs
v.
McLean,
Decree reversed.
