The factor often provides a store, together with a complete selling and office force, and every facility for receiving, storing, selling, and shipping the goods, and for financing the business. The salesmen of the house travel throughout the country, reaching all the important markets, and the managers of the different departments, who thus understand the needs of the market, are in a position to advise the mill with intelligence and exactness as to the kind of goods which should be made to meet the requirements of the trade. The cost of warehousing and of insurance on the merchandise is also paid by the commission agent. [Illustration: _Spinning room in a large mill. These are all ring spindles_] The prices at which the goods are to be sold are fixed by the mill, but, of course, they will finally sell at prices determined by the market conditions. As the goods are sold, the amounts which they bring are credited to the mill, less whatever has been advanced against them. The selling agent also stands ready, no matter on what time and terms the goods may be sold, to credit the mill with the net value of the sale, less 6% interest for the unexpired time within which the customer may pay, and from this interest charge also he secures part of his return. Of course if bank rates are very high, as they sometimes are for short periods, the factor may be out of pocket on the interest account, instead of making profit. As the goods are sold, so are the equities in them released, and the balance is credited to the mill. If, however, the goods sell at a loss there will be no equities coming to the mill, and, in fact, there are not infrequently deficiencies to make up. For these services, and according to the nature of the goods being sold, various commissions are charged, usually ranging between the limits of 4 and 8% of the net returns of the sales. Plain unfinished goods which are marketed in large quantities are charged for at a relatively low figure, while fancy goods, sold in smaller quantities and requiring more effort and expense to sell them, are charged for at a higher figure. The selling agent also guarantees the credits of the firms to which he sells, so that no losses for bad debts can fall upon the manufacturer, but, at the same time, he will decline orders from any concerns except those with whose credit he is entirely satisfied. Not infrequently when the manufacturer conducts his own selling operations, he will use the facilities afforded by the commission house for the financial part of the business only, taking advances on his goods, having his sales cashed, and his credits guaranteed, etc. For these lesser services, of course, the commissions charged are smaller.
