Capt. C. H. McAllister, president of the American Bureau of Shipping is chairman of the committee and C. J. Jefferson is active head under Capt. R. D. Gatewood, manager of main- tenance and repair. Just four years ago in. the May 1923 issue of MARINE REVIEW the per- formance record of the Hog Island class of freight ships was published, and from these actual records the standard performance chart (also pub- lished in that issue) was prepared. Ever since this time performance records of this class have been care- fully checked, compilations made for six-month periods and ratings awarded. The accompanying Table I gives the actual average performance and stand- ing of each Hog Island freighter for the six-month period, July, 1926 to January, 1927. The particulars noted are: observed speed in knots; fuel per mile in pounds; and the standard efficiency in port and at sea. In the chart above, observed speed in knots is laid off horizontally while pounds of fuel per observed mile is noted in the vertical scale. Average observed speed in knots and average pounds of fuel per observed mile for each of the Hog Island class of freighters for the last 6 months of 1926 are plotted on this chart. All of these figures are in turn averaged and the result is plotted as the total average observed speed and pounds of fuel per observed mile for this period. As a comparison a similar average result has been plotted for the per- formance of the same fleet in 1922 before the fuel conservation committee had begun its work. The difference in favor of the performance of this fleet during the last six months of 1926, with the committee actively in control, with that of 1922 before it began to function is convincing evi- dence of the value of the work now being carried on.
