PREFACE.

TO

THE very extensive and increasing demand for the “HAND

THE LOCAL MARINE BOARD EXAMINATION,” and the universal approval its general arrangements have received, have induced me, in preparing this Edition, (the 25th) to make further additions to its pages, by giving the Rules and full explanations for working the required problems; which, I trust, will render it deserving the continued patronage of those desirous of making themselves thoroughly competent for passing the Local Marine Boards.

The Hand Book being professedly nothing more than a Guide to the Pupil preparing for his Exainination, all extraneous subjects have been avoided, as they would only confuse instead of directing him. All other problems are left to the Epitomes,--their proper place,—as they are there treated on at greater length, with the requisite Tables at hand, without which even the Examination Papers cannot be worked, and therefore every student must have an Epitome.

The Work will be found to contain all those Questions and Exercises in Navigation and Steam, required in preparing for the different grades in the Profession,-inde

pendent of Seamanship,-a knowledge of which can only be acquired by service at sea.*

The Arithmetical Questions and Exercises in Logarithms, which have been introduced at the commencement, will be found useful, as preparatory to the Examples in Nautical Astronomy.

All the Questions in the First Paper are fully calculated, to assist the unpractised Pupil, and likewise those who may be obliged to study without the aid of a Master.

To the other Papers are only given the more prominent portions of the solutions, thereby leaving the Student to do something for himself, by studying the Rules, and endeavouring to fully understand the use of Logarithms and other Tables in the Epitome. If properly and accurately worked out, the Answers should not deviate, in any case, more than 5" or 10" from those given at the end of the book, such difference arising from the Dip and Refraction Tables which the student may use.

It cannot be too deeply impressed on all, that an accu

* Mrs. Taylor has published a work on Seamanship, carefully examined and corrected by several very experienced Commanders in the Merchant Service, which contains all the required answers in Seamanship; great care has been taken not to overburden the memory by useless matter, but just to give such brief information as will help the pupil to put his own ideas into fitting words. To the Edition just published, (1865,) Questions and Answers on Seamanship for Extra Masters have been added. The method of using Mortar and Rocket Lines, as directed by the Admiralty ; putting boats through a surf, and other valuable information useful in a sailor's life.

rate knowledge of Time is essentially requisite, without which no question in Nautical Astronomy can be correctly solved. Extracts from the “Nautical Almanack” for 1868, are given at the end of the Work, that the Questions may be solved without the Almanack.

Part of the very useful paper with accompanying Diagrams, on the Rule of the Road, which was originally published in the Mercantile Marine Magazine, has been added to this Work, -the great necessity for a better knowledge of this important part of a Seaman's duty, being obvious to all who take an interest in affairs connected with our Mercantile Marine, and the very simple directions there given, with Diagrams illustrative of ship's positions, and best mode of manoeuvring when placed in imminent danger, will be found of service in the every-day practice of the Seaman's life.

Directions, with a Diagram, for working the Questions in Current Sailing, by which the principle is fully demonstrated, have likewise been added.

The method of finding the height of the water at any time of Tide, is likewise introduced and explained.

In the Examination for Extra Masters have been added,

First,—A fully worked example of the Latitude by Double Altitudes of the Sun, verified by Sumner's method,—the rule, unassisted by calculation, presenting a difficulty to some,
