PILOT CHART OF THE GREAT LAKES. 'The new pilot chart of the great lakes just issued by the Hydrographic Office is full of interesting information. It illustrates the wide and useful field of work in which that branch of the gov- ernment service is engaged. Not content with notifying lake navigators of. all changes affecting navigation, by means of weekly notices to mariners, the hy- TAe Marine REVIEW drographic office nda use of its pilot chart to convey valuable information, outside the scope of the notices to ma- riners. . The present edition is devoted largely to treating the question of local mag- netic attraction, showing the points on the great lakes where it is found, and . the dangerous effect it has on the com- pass, leading vessels ashore. The hydrographic office desires to en- courage the use of the pelorus for the safety of the ship. Tables are given on this chart showing the corrections to be applied in working the pelorus. The equation of time for 1910 is given for every day during the year, and the cor-_ rection to be applied to Standard time to obtain local mean time is given for every half minute. - Changes in deviation due to anes from light to loaded with coal and ore are shown. The result of experiments made last summer by the hydrographic office with a typical ore carrier is given, together with a curve showing the devia- tions under all conditions. The distances between 119 ports on the great lakes have been computed by the hydrographic office, making a total: of nearly 14,000 distances, all of which are tabulated in convenient form on the pilot chart, so that the distance between any two. ports can' be seen at a glance. .« The office also takes a great deal of. interest in the strandings which occur on the lakes, and has marked off on the chart the place where each of the 208 strandings of the year 1909 occurred.
