The contract of agency is governed by the general principals of contract law; there is no reason why it should be otherwise, hence if the terms of the contract in reference to the duration of the contract is agreed upon, this fixes the rights and obligations of the parties in this respect. If X is hired for one year to sell goods for another, the agency extends for one year and no longer. If X is hired to sell a horse, the authority terminates with the sale of the horse. So, if the agent is to continue only until he has accomplished some certain work, the agency ends with the accomplishment of the work.5
