Vic. 1.—Sources of milk and cream supply of Detroit, and the steam and electric rail- 
ways over which most of it is transported to the city. 
shows that the greater part of Detroit’s supply of milk was pro- 
duced within 30 miles of the center of the city. Some shipments of 
cream originated in zones 100 miles distant or more. Because of 
the stringent regulations of the board of health in regard to city 
dairies. the quantity of milk produced within the city was negligible.
