The governor, with advice of the council, upon application of any convict under sentence of death may grant him a pardon on condition that he shall be imprisoned for life or any term of years expressed in the pardon, and upon such further conditions as may be thought just; and the governor's warrant, reciting such conditions, shall be sufficient authority to all officers to carry into effect such conditions, as if the same were the original sentence.
