ated in pts. and in degrees from 0° to 90° as heretofore. The bearings of leading and clearing marks, &c., will be given both true and magnetic, and a note to this effect will be placed on the title of the charts. Example.—The bearing S. 40° W. true, with a variation of 12° E., will be shown thus: 220° (S. 28° W. mag.). (b) In Sailing Directions: Bearings will be given as true only, in degrees from 0° (N.) to 360°, measured clockwise; and a note to this effect will be given in the title page, in the advertisement, and in the page immediately preceding page 1 of all volumes of Sailing Directions. The variation will continue to be given on each page as at present, so that magnetic bearings may be obtained when required. This alteration will be introduced gradually. (c) In Notices to Mariners: All bearings will be given both true and magnetic in a similar manner to that adopted on charts, the necessary alteration being made in the heading of the notices. (d) Lists of Lts.: Bearings will be given as true only, in degrees from 0° (N.) to 360°, measured clockwise. On each page of the Lists of Lts. in which this alteration has been carried out, a footnote will be placed stating that all bearings are TRUE FROM SEAWARD. This notice (Notice No. 1619 of 1911) will be republished on the 1st Jan., 1912:—
