 Thus, the total tonnage handled by the Gulf ports during the calendar year
 1929 is 93 percent larger than the 1919 figures, the absolute increase being over
 32,500,000 short tons during the period. The small volume of the tonnage shown
 as "Coastwise receipts" shows that this increase could not have been in the trade
 between the Gulf ports themselves, but must have been practically confined to
 traffic between the Gulf and foreign countries or between the Gulf and Atlantic
 ports; or, in other words, to traffic that is interested in the proposed canal.
 10. Potential canal tonnage.-Not all of the commerce shown in the preceding
table would have occasion to transit the canal. Therefore all the cargo and all
the vessels in the Gulf trade for 1929 have been traced. The result is set out in
the following table:
