Bulletin 202, Cost of Handling Citrus Fruit Floor labor cost was the highest each year in the group of packinghouses that operated at less than 20 percent of full ca- pacity and lowest each year in the group that operated at the highest percent of capacity but did not show a cons stent rela- tion to this factor. Since floor labor can be hired as needed, this result would be expected. Packing labor, picking, hauling and material costs were not influenced by the percentage of the time that the packinghouses ran at full capacity. 1.40 1.35 1.30 1.25 I.?0 1.15 1.10 1.05 i.oo .95 ) .90 .75 .70 .05 510 15 2 5 30 35 40 45 50 55 60 65 70 75 80 5 90 95 100 110 Percent of time packinghouse ran at full capacity Fig. 97.-Relation of percent of time packinghouse ran at full capacity to cost per box for 88 packinghouses, season 1924-25. Firms oper- ating pre-cooling plants not included. When the percentage of time that the packinghouse ran at full capacity was correlated with cost per box, the coefficient was -0.35302 0.06281 for 88 packinghouses without pre-cool- ing for the 1924-25 season, and -0.32036 0.06579 for 85 pack- inghouses for 1925-26. The influence that the percentage of time the packinghouse ran at full capacity has to cost of handling citrus fruit per box is shown for each year by dot charts, Figs. 97 and 98. Of those firms that operated for a higher percentage of the time than the average, only five for 1924-25 and seven for 1925-
