-12- picked and hauled. On this basis of comparison the dealers had 40 percent more capital invested per 1,000 boxes than the packers ($74 for dealers and $53 for packers). They also had 31 percent more volume per firm. None of the costs in Tables 1 and 2 includes interest on capital invested in picking and hauling equipment. Interest paid by the firms for the use of borrowed capital is in- cluded, though very few had interest expense. If interest at 5 percent were included on the book value of the operator's capital it would amount to .32 cents per box picked and hauled. Variation in Cost Between Firms Total cost varied rather widely between firms for providing the same service. These variations in total cost for picking and hauling in 1953-54 are shown in Tables 4, 5 and 6. Not enough is known about the individual firm's operations to provide much information about reasons for costs being high or low. Costs do not seem to be related to the total volume of the firm. In fact some of the smaller operators had relatively low costs. Comparison of 1953-54 Costs with Previous Seasons Total picking and hauling costs for 1953-54 were not much different from the averages of preceding seasons (Table 7). Buying and selling costs per box have declined somewhat each season, and hauling costs have shown the same tendency. No definite trend is shown by the picking costs. The fluctuation in total costs each season is wider for tangerines than for oranges and grapefruit. Very few of the citrus dealers picked them with their own crews, and packinghouse crews picked them in much smaller volume than other citrus.
