APPENDIX.

NOTICE.

By an Order in Council, dated 24th March, 1880, Article 10 of the "Regulations for Preventing Collisions at Sea," which was to come into force on the 1st of September, 1880, is suspended until the 1st of September, 1881, and in lieu thereof the following Article, being No. 9 of the previous Regulations shall remain in force until the 1st of September, 1881.

"Art. 9. Open fishing boats and other open boats shall not be required

to earry the side lights required for other vessels; but shall, if they do not carry such lights, carry a lantern having a green slide on the one side and a red slide on the other side; and on the approach of or to other vessels, such lantern shall be exhibited in sufficient time to prevent collision, so that the green light shall not be seen on the port side, nor the red light on the starboard side.

Fishing vessels and open boats when at anchor, or attached to their nets and stationary, shall exhibit a bright white light.

Fishing vessels and open boats shall, however, not be prevented from using a flare-up in addition, if considered expedient."

PROSPECTUS.

The first part of this work consists of the first parts of Arithmetic required in the following Sections.

The second Section consists of an explanation of so much Algebraic Equations as will enable the Candidates to read and understand the Questions in the form that many of them are now given by the Board of Trade Examiners.

If Students cannot read the Questions in the form in which they are given at the Examinations, they must overload their memories with such a mass of Verbal Rules as scarcely any memory can retain, and judging from his own experience as a Teacher, the Author considers it much easier and better in every way for the Pupil to solve the Questions by Algebra, rather than by the Complex Rules of ordinary Arithmetic.

In the first case, they have an engine which is powerful enough for the work it has to do; in the second case, the engine is too weak for its work, and it is almost sure to break down.

The Author has given just sufficient of the principles of Algebra to enable Candidates to read and apply the formulæ with facility, but he will probably at a future time go deeper into the subject.

Many of the Questions are given in Fractional form, and the Author has freely applied the principle of cancelling so much used by expert Arithmeticians.

In the first few Examination Papers every figure required is set down; and afterwards, as the work is in an especial manner adapted to the wants of Engineers at Sea who are preparing for Examination, the principal steps in the solution of every Question are set down.

This Section also contains an ample selection of Indicator Diagrams, many of them taken by a well qualified Gentleman, and all fully explained by him.

The third and last Section contains the Answers to the Elementary and Verbal Questions, written by another able Gentleman.

And the Work concludes with a short explanation of Engineer Drawing, and Detailed Drawings of Engines with Dimensions, by other competent Gentlemen.
