ing possible per day through every- 

 other-day pick-up; but, with most 

 road patterns in the region studied, 

 the route mileage reduction per day, 

 resulting from every-other-day oper- 

 ations, might be as little as 35 or 

 40 percent. Regardless of whether the 

 route-mileage per day is shortened 

 by 50 percent or by 35 percent, the 

 important fact is that the saving 

 shown is of a type which is con- 

 tingent on using every-other-day pick- 

 up (or even less frequent pick-up). 

 If now the load carried and the 

 distance travelled by the tank truck 

 were doubled, as could be the case if 

 the number of producers served is 

 doubled and the truck thus makes two 

 trips per day in place of one. the 

 cost can be reduced from 21 cents 

 to 17 cents per cwt. This situation 

 is set out in Example III. It assumes 

 that the wage bill would be doubled, 

 and makes no assumption as to 

 whether the added hours of work 

 would be put in by the same driver 

 or by a second one. The economy 

 derived from fuller utilization of the 



truck stems from the fact that about 

 $2,200 of the tank truck's yearly ex- 

 penses are fixed. 



There are some comparisons be- 

 tween vehicles in Table 35 and ve- 

 hicles in Table 36 which would be 

 misleading because unlike the 



comparisons set out in Table 37 — 

 they would not involve practices 

 which were alternatives to each other. 

 For example. Truck No. 2b in Table 

 35 (a vehicle hauling cans) and 

 Trucks 1 and 2 in Table 36 (tank 

 trucks) all traveled 50 miles per dav. 

 Each of these three vehicles assem- 

 bled 86 cwt. per day. The cost per 

 cwt. was closely similar for the three 

 vehicles, but with the can truck 

 slightly less costly than the other 

 two. The cost per cwt. amounted to 

 19c for the can truck, 20c and 21c 

 respectively for the two tank trucks. 

 The two tank trucks seem, at first 

 glance, to have been making an un- 

 impressive showing. 



However, they were already using 

 every-other-dav pick-up and — des- 

 pite that — they had to travel the 



Table 37. Comparison of Can and Tank Truck Costs per Cwt. of Milk 1 



1 Example I in this table is Truck No. 2a from Table 35. Examples II and III 

 in this table are Trucks 2 and 3 from Table 36. They were selected for comparison 

 because I and II have identical loads; III is a variant of II; and I, II. and III 

 all involve vehicles of about the same size. 



2 The same load as in Example I, for half the mileage per day. This does not 

 assume the full utilization of the truck possible by serving other routes to increase 

 the total pay-load. 



3 In Example III, 8,600 pounds is carried on each of two trips. Each trip is 50 

 miles long. Compare the load and mileage in Example III to those of Examples 

 I and II. 



4 Weight of vehicle plus a full load.
