cabinets, and most of the equipment required in a modern business 
office.

tory has to be covered and for very scattered retail trade the auto- 
mobile may be used economically. Use of horse and wagon, however, 
is the most common and satisfactory method of delivering to retail

one extra man will be required on an automobile truck. The constant 
stopping and starting necessary on a retail milk route is not favorable 
to the use of an automobile for such delivery, although recently 
electric-driven trucks are giving economical service. 
The quantity of goods that can be delivered from a wagon or 
truck depends primarily on how scattered the trade is, the method
