Figure 1 shows the present route structure in the part of New Hamp- 

 sliire ill which tliis study was made. In the chart an attempt has been 

 made to show conditions in one segment of the area to indicate not only 

 commercial truck routes, but the routes (in a general way) of individuals 

 taking their own milk to market. Each solid line represents a commer- 

 cial route; broken lines represent self-liaulers. Different colors are used 

 to differentiate between markets. (Black for Nasliua, Concord, and La- 

 conia, red for Manchester.) Data for all direct-liaul routes operating 

 to the four cities under consideration are given in Ai)pendix Table I. 



In figure 2 the first step in reorganization has been completed. While 

 no cliange in milkshed areas has been made, and self-haulers remain as 

 tliey were, truck routes serving those already shipi)ing on commercial 

 routes have been completely reorganized. Long study of figures 1 and 2 

 is not necessary to indicate the large reductions jiossible in mileage 

 Iravi'led and number of trucks needed. Tal)les I and 11 indicate a re- 

 duction in iiuiiibcr of routes (including stub routes) from 52 to 88, or 

 'M per cent, and in mileage traveled, from 2,086 to 1,433, or 31 pci- cciil
