Bul. 639, U. S. Dept. of Agriculture. PLATE III. 
Fic. 1.—ONE OF THE LARGEST CITY MILK PLANTS, WITH A CAPACITY FOR HANDLING i 
APPROXIMATELY 15,000 GALLONS DAILY. 
The average per gallon investment for the group of largest plants in Detroit was approximately $30. | 
Filia. 2.—ATTRACTIVE BUT EXPENSIVE EQUIPMENT. 
The disproportionate per gallon investments in equipment between small and large dealers are 
caused mainly by the well-kept and attractive horses, barns, wagons, and wagon sheds. Such 
costly investments, however, together with other advertising expenses, are necessitated by 
competition.
