Sec. 152.SAME; POWERS IN RELATION TO PROPERTY. Unless otherwise prohibited or not contemplated in the trust instrument, such trustee corporation may by gift, grant, devise or bequest, take, receive and hold any property, real or personal, so given, granted, devised or bequeathed from other persons than the person or persons by whose deed, will or other instrument the trust was originally founded. Any 2 or more persons may by the same instrument or by separate instruments, give, grant, devise, or bequeath property in trust, for any of the purposes mentioned in section 148 of this act,  1 to the same trustees upon such terms and conditions as may in such instrument or instruments be agreed on, and such trustees, if authorized to incorporate, shall attach to the articles of incorporation each and every one of such agreements, and shall be governed by the conditions therein imposed upon them, if not incompatible one with the other. After incorporation to carry out the express directions or conditions of any such trust instrument, no such trustees shall thereafter accept any gift, grant, devise, or bequest upon any condition or conditions incompatible with the articles or with any instrument required to be attached thereto.
