For example, the agent at Rock Hill, S. C., has a shipment of flour in sacks milled from wheat received from a point 75 miles distant from Rock Hill, to be reshipped to a point 50 miles from Rock Hill. In this instance the total haul is 125 miles. The rate on the wheat into the mill is 19 cents, the rate on the flour in sacks (Class C) for a distance of 125 miles is 27 cents. Shipments should be waybilled from Rock Hill to destination at the difference between the rate on the grain into the mill and the rate on flour in sacks for the combined distance, or 125 miles which is 8 cents per hundred pounds.
