5 3 EDITORIAL TANE is becoming increasingly popular as a medium for publication of student articles. This is demonstrated by the size of this issue which has almost twice the content of the last volume. For this reason future editors may find that they will have to be more selective in the type of article which they accept for publication. This becomes more apparent as it is realised that TANE has just about reached its optimum size. The cost of publishing a larger volume, or even a series of smaller issues per year, would push its price up to a level which would lessen its distribution to students of university or pre-university level who gain most benefit from it. Although the standard of articles has gratifyingly risen in the last few years, the journal runs the danger of becoming indistinguishable from a multitude of other publications which deal with botany, geology and zoology. We do not think this course would benefit our contributors in particular and TANE in general. An important feature of TANE should be the publication of articles from the Auckland University Field Club, and from other students who are making their first attempt at scientific writing. Because the Editorial Committee consists of fellow students, inexperienced authors get a fair amount of understanding assistance in the final preparation of their manuscripts. This eliminates, to a large extent, the timidity and sometimes discouragement of students attempting to publish in other, more well known, journals. There are other aspects of TANE which deserve consideration. On reading through previous volumes one notices a large number of animal and plant species lists, especially from offshore islands. Although at the time these exercises may seem to have little value, they are necessary to demonstrate changes in communities over a period of time. This is important in assessing the effect of proposed changes and for discovering more subtle long-term environmental modifications. For this reason we believe that the monitoring of vegetation quadrats and the compilation of species lists should remain an important part of Field Club activity and TANE articles. Next year we will publish several articles on the geology and natural history of another of our offshore islands, this work resulting from a Field Club scientific camp. Studies of this nature are gaining increasing relevance in the light of the widespread pollution and conservation debate. To know how to find, alleviate or perhaps solve such problems, a large amount of sometimes relatively simple and often tedious research must be carried out. To this end we hope in the future to publish articles which will give pointers to the type of research that can be done to elucidate the factors involved. We do not presume to suggest that any of us can bring about a revolution in man's treatment of his environment. Rather, we hope that by becoming involved, in even a minor way, in the scientific problems of pollution and conservation, some of us may succeed in convincing a few people of the need for preserving a specific part of their environment or the danger of a case of pollution. If each of us can do even that much our task would have been worthwhile.

7 INSTRUCTIONS TO AUTHORS TITLE The title should be kept as short as possible. TEXT Manuscripts must be typed (double-spaced) on one side of quarto pages with an inch margin all round. All matter to be printed in italic type should be underlined. The first mention of a species should be by its Latin If a common name is to be used it should be placed in brackets after Latin name which need not be used again in the text. Generally papers should be divided into the following sections: mary, Introduction, Materials and Methods, Results, Conclusions and cussion, Acknowledgements and References. The summary should be f, giving the main results of the work published. For longer articles in which the summary is too long for reproduction by abstracting journals, an abstract should be included in the text before the summary. For abbreviations and points of grammar and setting out of the text inexperienced authors are referred to 'New Zealand Government Printing Office Style Book'. Government Printer, Wellington. TABLES These should be set out on separate sheets numbered in arabic numerals and given a concise heading. FIGURES These should be drawn in black ink on a sheet of good quality white or tracing paper. The size of the printed area of TANE is 4V4x7 l /a ins. Figures should be drawn at least twice the final size but not so large that it must be reduced to less than one-third of its original size. All labelling must be stencilled on the figure and be of a size to be clearly readable in the reduced form. Captions should be numbered in arabic numerals and typed all together on a separate sheet, not inserted on the actual illustration. The position of figures should be indicated in the margin of the text and the author's name, title of the article and its position of insertion in the article should be lightly pencilled on the back of each figure. PHOTOGRAPHS These should be on smooth-surfaced paper, the edges of which must be trimmed square. It is important that photographs contain a reasonable degree of contrast to ensure a clear reproduction. Photographs are referred to as figures and are numbered in arabic numerals consecutively with other illustrations. REFERENCES - These are listed alphabetically at the end of the paper and should have been referred to in the text.

REPRINTS - 25 reprints are supplied free to authors (20 or 15 each where there are two or three authors). Additional reprints may be ordered in advance and bought at cost price at the time of publication. Authors are requested to see that their manuscripts are in finished form and completely ready tor publication so that corrections may be reduced to a minimum.
