Stephen Johnson Field,
Dillon v. Barnard — Opinion of the Court
“ Such expectation, however reasonable, founded even upon the express promise of the employer that the funds shall be thus devoted, of itself avails nothing in favor of the contractor. Before there can arise any lien on the funds of the employer, there must be, in addition to such express promise, upon which the contractor relies, some act of appropriation on the part of the employer depriving himself of the control of the funds, and conferring upon the contractor the right to have them applied to his payment when the services are rendered or the materials are furnished. ”
