Section of Locust Point, Baltimore, Marine Terminal—1878 Famous Ports of America Show Remarkable Development RHAPS no other phase of American life shows _ such striking changes and advance- ments as the traffic and equipment of leading Ameri- seaports. It is therefore op- can portune and of special interest that MARINE REVIEW on its fiftieth anni- versary should consider a few ex- amples illustrative of this growth. It is obviously impossible to show more than a few of the seaports of the country. The two accompanying tables of comparative figures for foreign commerce for the three years 1849, 1876 and 1926 are in them- selves striking illustrations of our commercial growth. In_ considering the value statistics it must be remem- bered that the purchasing power of the dollar today is not what it was The author, Dr. Roy S. Mac Elwee, is com- missioner of port development for Charleston, S. C. He is author of Ports and Terminal Facil- ities, Port Development, Wharf Management, (with Taylor), Economic Aspects of the Great Lakes Ship Channel (with Ritter), etc. This article was prepared at the request of the editor. 60 By Roy S.

Such plans af- fected an entire port area and were carried forward for the benefit of all. The increased size of ships and _ in- creased volume of foreign commerce made new port facilities necessary and port construction in the United States beginning with the World war has been very active during the last decade. The greatest new develop- ment in American’ shipping and American ports has been, since the World war, through the Panama canal. The inter-coastal business has developed to enormous proportions and it is decidedly long sea voyage com- merce. The vessels engaged in it are large cargo liners. Constructive im- provements in terminal facilities and channels have been made to suit these large ocean going vessels. Beginning at the North Atlantic we will discuss briefly the ports of Bos- MARINE REVIEW—July, 1928 ton, New York, Philadelphia, Balti- more, Norfolk, Charleston, Mobile, New Orleans and San Francisco. Port of Boston MPORTS at Boston during the year ending June 30, 1878, were valued at $40,679,714 and exports at $48,121,- 119 while in the calendar year 1927 the imports were valued at $261,573,- 994 and the exports at $42,435,418. Intercoastal shipping is becoming a great factor in the port’s’ business. In 1927, 522,976 long tons of mer- chandise were received from the Pa- cific coast. The shipments to the West coast for the same year amount- ed to 102,873 tons.
