time the draft is honored by the consignee, who will eventually borrow
against the shipment.
Besides the country elevators, there are some river elevators,
which originally were operated as sub-terminals, i.e., to feed the terminal
elevators. In recent years, due to the growth of the poultry industry in
the South, and, above all, to the demand for barge grain at the Gulf for
export, most of the grain originating on the river did not go to the
terminal houses. For instance, in 1964, only 15 per cent of all the barge
grain shipments from Illinois were sent to Chicago and other terminal
places. Even a smaller percentage of the barge corn shipments reached
these places. Many of the river elevators do not have rail facilities. They
generally rely on grain bought from country elevators which deliver by truck.
The terminal elevators are located in Chicago, Peoria, and
St. Louis. They buy from cash grain merchants, river elevators, and country
elevators. Most of the terminal elevators can receive grain by barge, rail,
and truck. The terminal elevator, in turn, sells to processors, millers,
distillers, feed manufacturers, exporters, and sometimes to elevators in
other parts of the country. Most of their shipments are by rail or water.
They benefit from the rail transit privilege for the grain received by rail
or by barge, when the inbound barge shipment is regulated.
B. Some detailed information is available concerning part of
the grain movements just described. In some cases these data deserve quite
a number of comments. However, the most important data will first be quickly
described, in order to indicate the kind of concrete problem that will be
dealt with later.
The Board of Trade of the City of Chicago made available to us
monthly data covering all the grain shipments from Illinois to Chicago by
truck and by rail during the year 1966. These include the shipment origins,
the name of the railway carrying from these origins, the rail mileages, the
rail rates, and the quantity of each shipment. For the rail shipments, the
number of days it took for each shipment to reach Chicago was also given.
