It seems likely that the source of fluid milk products in Glades County was from one or more firms of this type. Amount and Source of Fluid Milk Products Sold (Consumed).--In this analysis, it was assumed that sales by plants were synonymous with consumption. As a rule, plants in each area sold the major proportion of their volume within the market area in which they were located. How- ever, in each area one or more plants sold products in market areas other than the one in which they were located. Northwest Area.--Total sales within the Northwest area by Florida dairy firms were 20,355,000 for the two months (Table 37). Area firms also marketed 677,700 pounds of fluid products in several near-by counties in Southeastern Alabama making total sales 21,033,000 pounds. Firms within the area accounted for 99.4 percent of the amount sold. Northeast area dairy firms sold 124,000 pounds of products in Dixie and Taylor counties. This was 0.6 of all marketing within the area. The amount sold in Escambia County was 8,632,000 pounds (Figure 10). This was the largest volume for any county in the area and was 42.4 per- cent of total area sales. Sales in Leon, Bay and Walton counties accounted for one-third (33.2 percent) of the volume distributed. In nine of the twenty counties in the market, sales were less than 1.0 per- cent of the total. Local dairy firms sold 4.4 percent of their total volume outside the market. Of this amount, 3.2 percent was in Alabama and 1.2 percent in the Northeast Florida area. These data indicate that only relatively minor amounts of processed fluid milk products were moved into or out of the Northwest area during the period studied. Northeast Area.--Total sales for April and October 1959 in the area were 25,393,000 pounds. Of this volume, only 256,000 pounds (1.0 percent of total) originated outside of Northeast Florida. These sales were to consumers in two counties adjoining Northwest Florida, by firms located in that area. Total marketing of fluid milk products by local dairies were 30,979,000 pounds. The largest portion of sales was in Duval county (Figure 11). Slightly under three-fourths (74.8 percent) of total sales were in this one county. Dairy products processed in the Northeast market were distributed throughout the fourteen county locality. Local milk distributors accounted for 99.0 percent of within market sales in addition to considerable amounts moved into other areas. Sales were made in six of ten counties in Central Florida and two counties in
