16 BULLETIN 53, U. S. DEPARTMENT OF AGRICULTURE. 
D. C., uses normally about 17,000 cords of wood fuel annually, most 
of which is brought up the Potomac by sailboats with an average 
capacity of 30 cords. 
Freight rates on cordwood vary in different sections of the country 
and on different railroads. At this time, on account of readjust- 
ments, it is not possible to give very definite information on freight 
rates. Recently the rate for distances of about 10 miles has averaged 
about 50 to 60 cents, and has sometimes reached $1. Around 100 
miles the rate has averaged $1.50 per cord, but has in some cases been 
as low as $1 and in others as high as $2. 
CAR CAPACITIES.
