_Overhead._--In each domestic factory the total overhead charges were obtained and the ratio of these charges to the total direct labor cost of the respective factory was computed. This ratio, expressed as a percentage of direct labor, was applied to the direct labor cost of individual hats to determine the overhead charge to be apportioned to each hat. SELLING EXPENSE (_a_) _Domestic._--The ratio of total selling expense in each factory to total manufacturing cost (material, labor, and overhead) was first determined. This ratio (expressed as a percentage of total manufacturing cost) applied to the manufacturing cost of the selected hat determined its proper share of the total selling expense. Firms organized to deal directly with retailers uniformly had higher selling expenses than those whose products were marketed chiefly through jobbers. The average selling expense of the selected hats was $1.64 per dozen, or 10.8 per cent of the average manufacturing cost. In selling expense is included the charge for cases and other packing material. (_b_) _Foreign._--Costs of selling hats to importers in the United States are included in the general overhead expenses reported by foreign companies, but are an inconsiderable item when compared with manufacturing costs. No expenses of the offices maintained in this country by foreign manufacturers have been included. TABLES SHOWING COST COMPARISONS In Table 8 are shown the costs of domestic and Italian men's sewed straw hats, irrespective of the type of braid used in their manufacture. In Table 9 are shown similar cost data for domestic and English hats. In both tables costs are shown with and without transportation charges on foreign hats, and ad valorem rates of duty necessary to equalize differences in foreign and domestic costs have been computed.
