Since the agency comes into being by the appointment of an agent and exists purely by the will of the principal, the relation of principal and agent may be terminated practically, whenever the parties see fit to elect. Where the agent has engaged himself for a fixed time, and where the principal has agreed to continue the agency for the period stated, a breach of the agreement would mean the liability in damages to the party injured. But the power to terminate the agency is always practicable, even though the right to revoke, or renounce the agency is not present.1

A contract of agency for a fixed term, however, is only binding on the principal for that term and only binding where the agent faithfully performs his duties, and is not himself guilty of a breach of contract; this implied condition being broken, however, on the agent's part, the way is open for the principal to revoke the contract without rendering himself liable to the agent. The agent is, however, entitled to reasonable compensation for his sendees already rendered unless guilty of such extreme, improper, or wilful acts as to have brought more injury than benefit to the principal.2

In the case of who made a written contract, by which the first person was made the agent of the other, for the purpose of making sale of certain machines, the following was the statement of the time of duration of the agency. "Said B in consideration of the faithful performance of said A, of the obligation by him hereinafter assumed agrees to furnish the said A, such number of machines as the said A may be able to sell as his agent prior to October 1st, 1867." The agency was held to continue only up to October 1st, 1867 and by reason of the terms of the agreement, expired.3 So where one is given a power of attorney to continue while the principal is out of the state, the time so stated would fix the limit of the authority of the agent to act under it and no act of principal except his returning, would be necessary to bring the authority to an end.4

The parties may agree on a time for concluding the agency, when the agency will be there-by dissolved, or the agency may be merely at the will of either party, or, the accomplishment of a certain act may fix the limit of the authority of the agent, and the purpose of the agency having been fulfilled the authority is exhausted.
