Table XVI shows that the cost of delivering a quart of milk in the 
city is dependent upon many things besides the average number of 
quarts delivered daily by each delivery wagon. The most economical 
delivery was effected by a dealer who sold bottled milk exclusively, 
but delivered in relatively large quantities to retail stores only. The 
dealer whose delivery cost per quart was the highest had comparatively 
small average sales per wagon in relation to the proportion of sales 
made to wholesale trade. The figures suggest possible economies in 
milk distribution if all sales were made through the medium of 
established retail stores. The table, however, does not indicate the 
cost of delivering to the consumer by the retail stores. 
The item “investments in delivery equipment” includes horses, 
barns, wagon sheds, automobile trucks, delivery wagons, and sundry 
articles used in delivering milk. The reasons for the wide variations

Fic. 8.—Relation of size of business to fluctuations in daily sales at wholesale and retail. 
in delivery investments per gallon delivered are the varying propor- 
tions sold at wholesale, and the fact that some of the larger dealers 
had unusually high-priced horses and very costly stables. Such un- 
usually large investments in delivery equipment are maintained for 
advertising as well as for direct utility. (PI. III, fig. 2.) 
Figure 9 illustrates the cost of city delivery in relation to amount 
of sales on 14 city delivery routes. Routes Nos. 1, 7, and 9 were en- 
gaged in a strictly wholesale delivery of bottled milk to retail stores, 
restaurants, and hotels. The business on the other routes consisted 
mainly of retail delivery at the family door, with only a few de- 
liveries to grocery stores. 
The heavy line in the figure shows the variation in the value of 
daily sales on the routes. Pasteurizing and bottling expenses at the 
city plant are included in the item “cost of goods.” The item “ cost
