We think the trustees are not chargeable. The evidence satisfies us that the indebtedness of the supposed trustees was not due to the principal defendant in his own right. We are satisfied that it was due to him as agent of the Aitna Insurance Company. And it is well settled law that if the debt due from a supposed trustee is due to the creditor as agent, or factor, it is not attachable as his property. Cushing’s Trustee Process, § § 107-110. Willard v. Sturtevant, 7 Pick. 194; Bowler v. E. & N. A. Railway, 67 Maine, 395.
