Exceptions upon the disclosure of the trustees, by which it appears that the only foundation for their liability arises from a written contract between them and the principal defendant, and the only question involved is the amount due, if *125any thing, upon that contract. It is admitted that there was a breach of the contract by the principal defendant, and the trustees willing to allow him what he had earned under it, claim to have deducted from that amount the damages they have actually suffered in consequence of the breach by way of recoupment. In an action against them by the principal defendant, they would unquestionably be entitled to have this claim allowed. They can legally be placed in no worse condition as trustees. In either process they can be hable only for what is actually due under the contract, and this must be, if there is any liability on the part of the trustees, the amount earned by the principal defendant less the damages caused by his breach, deducted not by way of set-off, but by recoupment.

This does not violate the provisions of R. S., c. 86, § 64, excepting from the privilege of deduction by way of set-off claims for “unliquidated damages for wrongs and injuries.” This refers to independent claims, and not to such as arise out of the contract itself, upon which the debt is founded. The trustees are hable for only such sums as shall be found due upon the contract, less-what they have legally paid upon prior attachments. To ascertain this amount, by the agreement of the parties, the action is to stand for trial. Exceptions sustained.
