Publication of Notices and Circulars of Interest to Shipping.

All of the Panama Canal notices to mariners, notices to steamship lines, and general circulars of
interest to shipping in its relation to the Canal are published in The Panama Canal Record. For
this reason it is considered unnecessary to make a separate general distribution away from the Isthmus
of such notices and circulars to those receiving The Panama Canal Record. Shipping interests
are advised to look for them in this paper, which is supplied to them without charge.

THE PANAMA CANAL RECORD



June 17, 1931



Comparison of Canal Traffic in May, 1931, with May Traffic in Previous

Years.

Commercial traffic through the Canal during the month of May,
1931, with 428 transits, was the lowest May traffic since 1925, when
372 vessels, aggregating 1,847,682 net tons (Panama Canal measure-
ment), and carrying 1,823,042 tons of cargo were passed through.
In comparison with May, 1930, traffic for the past month declined 51
transits (10.6 per cent), 233,674 net tons (9.7 per cent), and 336,164
cargo tons (16.2 per cent), and in comparison with May, 1929,
decreased 96 transits (18.3 per cent), 311,946 net tons (12.5 per cent),
and 611,387 cargo tons (24.1 per cent).

In the tabulation below are shown the number of transits, net ton-
nage (Panama Canal measurement), and the tons of cargo carried
through the Canal during the month of May each year from 1915 to
1931, inclusive, and for comparison the monthly averages for the
corresponding fiscal year ending June 30 following:

CANAL WORK IN MAY, 1931.

The following is the report of the Governor to the Secretary of War,
of Canal work in the month of May, 1931.

Balboa Heights, C. Z., June 16, 1931.
The Honorable, the Secretary of War,

Washington, D. C.

Sir: I have the honor to submit the following report covering operations of The
Panama Canal during the month of May, 1931:

TRANSITS AND TOLLS.

During the month, 428 commercial vessels and 10 small nonseagoing launches under
20 tons transited the Canal. In addition to these there were 19 vessels belonging to
the United States Government on which no tolls were collected, making a total of
457 transits for the month, or a daily average on all traffic of 14.74.

Tolls on the 428 commercial vessels amounted to $1,923,452.18, and on the launches
to $44.70, a total of $1,923,496.88, or a daily average on all traffic of $62,048.29.

Commercial traffic in the past month was the lowest since November, 1926, during
which month the same number of vessels, 428, made the transit. The daily average
of commercial transits for May, 1931 (13.81), was the lowest since October, 1925, in
which month the daily average was 13.23 transits. The daily average tolls collection
on commercial traffic in the past month, $62,046.84, was the lowest since June, 1926,
when the daily average was $61,755.69. In comparison with May, 1930, commercial
traffic for the past month was lower by 51 transits and $239,446.42 in tolls, or 10.6
per cent and 11.1 per cent, respectively. In comparison with the previous month
there was a decrease of 25 transits and $90,896.95 in tolls, or 5.5 per cent and 4.5 per
cent, respectively.

Commercial traffic for the first 11 months of the current fiscal year in comparison
with the same period last year shows a decrease of 10.1 per cent in transits, 6.8 per
cent in net tonnage (Panama Canal measurement), 16.4 per cent in cargo passing
through, and 8.6 per cent in tolls assessed.

The total number of craft of all kinds transiting the Canal during the month of
May in the two preceding years and in 1931 are shown in the following tabulation:

1 Commercial traffic includes all ocean-going vessels paying tolls. Vessels in direct service of the United States,
Panamanian, and Colombian governments, including merchant vessels chartered by these governments, and vessels
transiting solely for repairs, do not pay tolls. Statistics on vessels not paying tolls are shown under "Noncommercial
traffic."

NATIONALITY OF VESSELS.

Fourteen nationalities were represented in the commercial traffic through the Canal
in May, 1931. Vessels of the United States registry, with 191, led in the number of
transits, while those flying the British flag, with 97, were second. Vessels of these

two nationalities made up 67.3 per cent of the total transits for the month. Vessels
of German and Norwegian registry were next with 32 and 29 transits, respectively.

CARGO AND PRINCIPAL COMMODITIES.

The total cargo through the Canal during the month of May was 1,925,452 tons,
a decrease of 336,164 tons, or 14.9 per cent, in comparison with May, 1930. Cargo
from the Atlantic to the Pacific aggregated 519,844 tons, as compared with 553,609
tons for the previous month, and 681,073 tons in May, 1930. From the Pacific to
the Atlantic there were 1,405,608 tons, as compared with 1,457,508 tons for the
previous month and 1,580,543 tons in May, 1930.

From the Atlantic to the Pacific various manufactured goods, totaling 165,006
tons, constituted the heaviest item of cargo, followed by phosphates with 44,274 tons,
mineral oils with 32,445 tons, cement with 18,812 tons, cotton with 15,385 tons,
paper with 15,307 tons, and tobacco with 14,303 tons. There was a decrease of
161,229 tons, or 23.7 per cent, in cargo moving in this direction as compared with
May, 1930.

From the Pacific to the Atlantic mineral oils constituted the leading commodity,
totaling in May, 1931, 314,546 tons. This was followed by lumber with 218,585
tons; wheat with 157,084 tons; sugar with 123,574 tons; ores with 98,325 tons; and
nitrates with 71,040 tons. Wheat shipments via the Canal increased 44,045 tons,
or 39 per cent, over May, 1930, and sugar shipments increased 8,658 tons, or 7.5 per
cent. The other above-listed items decreased as follows in comparison with May,
1930: Mineral oils, 94,434 tons, or 23.1 per cent; lumber, 77,379 tons, or 26.1 per
cent; ores, 76,015 tons, or 43.6 per cent; and nitrates, 32,289 tons, or 31.2 per cent.
In aggregate there was a decrease of 174,935 tons, or 11.1 per cent, in cargo routed in
this direction in comparison with May, 1930.



At present tolls are collected at rates of $1.20 per net ton for laden vessels and $0.72
per ton for vessels in ballast, computed on the basis of the Panama Canal rules of
measurement, with the provision that tolls shall not exceed $1.25 per net ton, nor
be less than $0.75 per ton as determined in accordance with the United States rules
of measurement of net registered tonnage. In order to ascertain the proper tolls
charges it is necessary, therefore, that the net tonnage of vessels transiting the Canal
be determined in accordance with both the Panama Canal and the United States
rules of measurement.

Due to this limiting proviso, the tolls actually collected last month on laden vessels
averaged $0,904 per net ton, Panama Canal measurement, and tolls on vessels in
ballast averaged $0.7195 per net ton, Panama Canal measurement.

Taking the traffic through the Canal for the month of May, 1931, the following
tabulation shows a comparison of tolls actually collected under the present method
of assessing tolls with the tolls that would have been collected on the basis of the
Panama Canal rules of measurement at the proposed rates of $1 laden and $0.60
ballast with no added charges for deck loads. The traffic for the month is segregated
