Where an agent simply exhibits samples of goods kept for sale by his principal, and takes orders from purchasers for such goods, which goods are afterwards to be delivered by the principal to the purchasers, and payment for the goods is to be made by the purchasers to the principal on such delivery, such agent is generally called a “drummer” or “commercial traveler.” Kansas City v.
