are not completed, the Candidate will be declared to have failed, unless the Harbour Master should see fit to lengthen the period in any special case.

154. The periods prescribed in the forgoing paragraphs are not intended to include the time occupied by the vivâ voce part of the examination.

155. In the virâ voce examination a reasonable time should be allowed for the Candidate to give his answers. No assistance should be given or leading question put.

156. It is anticipated that few Candidates will require the whole of the time allowed for completing the examination in navigation, but ample time has been given, so that Candidates may perform their work in a careful, clear, and legible manner, and to the entire satisfaction of the examiners.

157. Candidates, after finishing the problems required in the various grades on the first day of examination, should proceed, until the end of that day, with such subject as the definitions, chart, questions relating to cyclones, and compass deviation.

158. The Sumner problem (Exn. 6c) must on no account be given out to any of the Candidates on the first day of the examination, but should form the commencement of the Candi- dates' work on the second day. On completion of this problem, if included in the lower grade problems, the Candidates for Masters' Certificates should proceed with the problems (a), (b), (c), of the syllabus for that grade.

159. Degree of precision required in the solution of the problems:-

(a.) Candidates are expected to work out their answers to all problems where the answer required is a latitude, longitude or distance within 1 of position from a correct result; in finding the ship's position by Sumner's method a margin of 21 will be allowed. (b.) In such problems as the "Amplitude" and

Azimuth", where the bearing, deviations, &c., only are required, a margin of 3′ or 4′ from a correct result will be sufficiently accurate.

Alt-

(c.) Candidates for Ordinary Certificates are not required to correct for second differences in taking out the quantities from the Nautical Almanac.

(d.) In solving the Time Azimuth problems an answer not exceeding half a degree from the exact result will be sufficiently near. But in all cases the actual latitude, declination, and time used, together with the exact bearing from the North or South as given in the tables, must be clearly shown by the Candi- date on his papers.

(e.) In computing the time at which a given star will be on the observer's meridian, and the names of the stars near the meridian (sections (b) and (e) of paragraph 36), an approximation only is required, and it will be sufficiently precise if the Candidate works throughout with the nearest minute of time. In computing the approximate meridian altitude of star (section g) working throughout with the near- est minute of are will also be sufficiently close.
