EDITORIAL

We are beset by problems! It is hard to decide which is more pressing, the state of our finances or the deadline for copy. Last year T A N E was delayed, partly by A N Z A A S but mainly by late copy, this year I apologise in advance. In an effort to solve this problem we have decided to extend the deadline to the third week in Apr i l — hopefully a more realistic target date for people completing field work over the summer holidays.

Now to our finances. The last price increase was in 1974 and regrettable as it is we have had to raise prices again. Last year T A N E cost more to pro­duce than subscribers paid for it. The Student Subscribers price will remain the same as it is subsidised by the Auckland University Students' Associa­tion.

A successful trip to the Cavalli Islands has meant that once again T A N E is bursting at the seams. We look forward to next year when the results of renewed interest in the scientific side of the Club will be combined with the Offshore Island Research Group's Work on the eastern Bay of Islands.

In reply to the "Letter to the Edi tor" 1 am happy to be able to write that plans are afoot. The Field Club Committee recognises the need to increase the scientific output from Kawerua and is taking appropriate action.

Finally I would like to acknowledge the time and effort put into the preparation of papers by most authors (its only a pity that some put in too much time). It has been very rewarding and a great pleasure to work on this volume of T A N E .

INSTRUCTIONS TO AUTHORS (please read carefully)

TYPESCRIPT - Manuscripts (including tables) should be typed double-spaced on one side only of medium bonded A4 paper, with a left hand margin of at least 3cm. The original copy is required. AU matter to be printed in italic type (e.g. generic and specific names, not headings) should be underlined. At the first mention of a species, the scientific name should follow the common name in parentheses, e.g. pohutukawa (Metrosideros excelsa). Papers should be set out following the format of this volume of T A N E . A summary should be supplied with any article longer than two printed T A N E pages (about 900 words) and should provide a concise and clear summary of the basic results or conclusions of the article. The title should be kept as short and non-technical as possible. All measurements must be in SI units and dates should be given as 16 December, 1977. For abbreviations and points of grammar, inexperienced authors should consult the "New Zealand Government Printing Office Style Book" Government Printer, Wellington (copies available from the Editor).

TABLES - Wherever possible, Tables should be designed to fit upright on the page. They should be numbered consecutively in arabic numerals, and must be referred to in the text. Tables should be typed on separate sheets of paper, with an indication of their position in the left hand margin of the text proper. Units of measurement should be placed in parentheses at the head of the column, not in the body of the Table. Captions should be kept to a minimum, and abbreviations used wherever possible.

FIGURES - Illustrations should be numbered in consecutive arabic numerals regardless of whether they are half-tones (photographs) or line drawings (maps, graphs etc.). All figures must be referred to in the text, and should be cited as, e.g. Fig. 1 (with initial capital in the text). Citation of figures from previous publications should have an initial lower case letter. The author's name, an abbreviated title of the paper and the figure number should be pencilled lightly on the back of each figure. Line drawings should be executed in black ink on high quality white or tracing paper, approximately twice (but no more than three times) the size of a T A N E page (printing area 17.5 x 11.5cm). All lettering must be neat and clearly legible after reduction to final size. Half-tone illustrations must be of the highest quality, with good contrast. It is preferable that more than one photo make up a page in T A N E . Components of a composite picture should be firmly mounted on white card, and lettered as required e.g. A, B, C etc. Captions for all figures should be typed together at the end of the paper.

SPECIES LISTS - Authors should consult the Editor on layout of species lists before typing. Abbreviations should be used to indicate abundance and distribution.

REFERENCES - In the text, citations are to be by author's name and year, e.g. "(Brown 1970)" or " . . . .as stated by Brown (1970)". The list of references at the end of the paper is to be arranged in alphabetical order of the authors' surnames. Unpublished work or personal communications are to be acknowledged as such in the text, and not included in the list of references. Map references are to be cited in full in the text, not in the list of references, e.g. N18/345612 (NZMS 1 Sheet N18 Waipoua, 2nd Edition, June 1967). Titles of books are to be given in inverted commas; followed by the Edition, name and location of the Publisher and number of pages. Titles of periodicals should be given in full and underlined, followed by volume (and part) numbers, underlined, and page numbers, not underlined, lor arrangement and punctuation of references, see examples in this issue.

OFFPRINTS - Thirty offprints are supplied free to authors. Additional reprints may be ordered in advance and bought at cost price at the time of publication.

Authors are requested to have their manuscripts refereed before submitting them to the Editors. The Editors reserve the right to submit papers to a confidential referee of their own choice. Manuscripts must be in finished form and completely ready for publication when submitted to the Editors. Those not following the above instructions and the format of T A N E Volume 23 will be returned to the authors for correction.
