Orestes Was Employed as the Manager of Coral Gables Horse

Orestes was employed as the manager of Coral Gables Horse Farm,a business carried on by Coral Gables Inc.Orestes was responsible for the day-to-day operations of the farm,including the care and maintenance of the horses and the management of the staff.Calum owned all the shares in the corporation and was the sole director and officer of Coral Gables Inc.He was the only one who had authority to buy new horses.In January,Calum asked Orestes to go to the local horse dealer and buy two stallions.Orestes bought the horses.Orestes thought that he had been given a general authority to buy horses for the farm,but that was not Calum's intention.In February,Orestes went to the horse dealer without Calum's permission and purported to buy from the horse dealer two more stallions on behalf of the corporation.When the horse dealer delivered the horses and asked for payment,Calum refused.Can the horse dealer enforce the contract? If not,does the horse dealer have any other remedy?
