the permission of the secretary OF
| war under whose Jurisdiction the
navigable rivers are placed) build a
structure of predetermined dimen
sions which must be completely
shown in drawings before approval
by the secretary OF war, and from
which thereafter no departure will be
permitted.
Generally a prerequisite to the
secretary's approval is that whatever
prism is taken away by the new con-
struction from the flood section OF
the river, must be replaced by cor.
responding enlargement of the river
section by dredging beyond the struc.
ture to be erected. Engineers, in con.
templating a dock, should inform
themselves as to these harbor lines;
if not yet established they should re-
quest of the United States engineer
officer in charge Of the district, that
he establish harbor lines to which the
proposed structure may be adapted.
Cost Of Handling Machinery-If
the expenditure of city or town for
river terminal or dock should, as we
have shown above, be determined by
the amount of freight to be handled,
much more should the expenditure
for freight handling machinery be
thus determined; for while dock and
warehouse provide piling and storage
space, the freight handling machinery
determines the rate at which such
space may be filled and emptied and
the cost of doing such work.
with expeditions handling the
same dock space may accommodate a
greatly increased tonnage; and with
economical handling, warehouse
charges may be greatly reduced.
These features are well set forth in
Mr. Bowen's chapter on freight hand
ling methods.
while costs might be given In a
general way the committee deem it
wise to leave all such estimates to
the local city engineer, basing same
on manufacturers guaranteed rate Of
operation of each device; the local
lift and transfer distance: the local
cost of power and labor and the great
er or less continuity of operation; all
considered in connection with the
character and tonnage of freight in
each instance.
an conclusion your committee has
tried to maintain helpful and sug-
gestive attitude toward the promo
ton of the purposes of the league.
We have sought to furnish definite
information on proper river termin-
ais suitable to the needs of the cities
Of the Mississippi valley; to set forth
such general principles as will stand
ardize, SO far as possible, plans for
such river terminals as will most sat
isfactorily serve both boat lines and
shippers, and to put in definite form
the best engineering ideas in regard
to the general layout and methods OF
freight handlingg at these river ter
minals, with a view of helping in de-
termining the approximate cost OF
these terminals in regard to construc-
ton as we'll as operation.
purpose Of Public River Terminals
The purpose of these river ter
minals is: (a) To encourage the re-
vival of river traffic. (b) To provide
warehouse space for boats and ship
pers. (c) To insure the lowest ter
