A review of the foregoing will show that the estimated savings are based on the water-borne commerce of the Gulf ports as it actually existed in the year 1929. Much additional tonnage might well have moved by water that did not actually so move. Still other tonnage certainly would have moved by water under the advantageous conditions that would have been afforded by an efficient ship canal aeros Florida. For the purposes of this report special studies have been made of this potential commerce for the anal. These researches relate to the principal commodities of the Gulf trade, and under the general title of "Com- modity studies" are set out in division E of this report. 53.

A summary tabulation will be found in division D, exhibit 607, for 26 separate epmmodites including coal, petroleum, phosphate, pulp and paper products, lumber, cotton, four, sugar, and 18 others.

The totals do not include possible tonnage movements of sand, gravel, brick, stone, and oyster shell in local trade. The item of possible movement by water of additional Alabama iron and steel to Atlantic coast ports, through lower freight costs afforded by the canal, has not been included; nor has any account been taken of a lrge tonnage in scra-iron-and-other commodities likely to pae through the canal from South Atlantic ports to the Orient. There are grounds for believing that this tonnage might be considerable.
