K.W. DomierMember CSAE

This winter I had the privilege of spending four and one-half weeks in India under anexchange program sponsored by the Commonwealth Foundation and administered by theAgricultural Institute of Canada. I visited nine Indian institutions that grant bachelors,masters or doctoral degrees in Agricultural Engineering. In addition there were stops atthe International Rice Research Institute in the Philippines, the University of Science andTechnology at Kunnasi, Ghana (for the Canadian International Development Agency) andthe National Institute of Agricultural Engineering and the National College of AgriculturalEngineering at Silsoe, England.

Throughout my travels I was cognizant of the many contributions made by overseasadvisors. In the past twenty years a number of CSAE members including the late EvanHardy, George Bryce, Bob Rae, Art Strautman, Terry Oatway, Lionel Coulthard, HerbLapp, Barney Stephanson, Mel Hendrickson, Kaljo Pohjakas, Bob Hore and others haveserved in other countries.

In India I was able to spend several days with fellowCanadiansTracy AndersonandRuss Lunney who are working on the Coordinated Research Project for Dryland Agriculture. The Canada Department of Agriculture and the Canadian International Development Agency are assisting the Indian Council of Agricultural Research in trying to spreadthe green revolution to non-irrigated areas.

A number of Agricultural Engineers will be needed by the Canadian InternationalDevelopment Agency (CIDA) for advisory positions in many parts of the world. Will ourmembership or institutions be able to meet these needs? In many cases an institution,government agency or industry is thin in various areas (such as Soil and Water) so that thesecondment of even one person creates hardship to an ongoing program. Thislack of "benchstrength" may prevent an enthusiastic staffmember from accepting an overseas assignment.A solution to this problem will be needed if agricultural engineers in Canadawillbe able toparticipate in these programs.

Another school of thought concerning foreign assignments is that the advisor losesground in his research, teaching, extension or management activities. A successful researchscientist may for example, lose hiscontinuity of research funds, have hispublication recordinterrupted, and if he is on direct secondment, lose his annual merit increments. This neednot happen if the advisor keeps up in his field and the administration of his institution orcompany are prepared to accept foreign experience asanenrichment for theirstaff.

Although the Canadian Society of Agricultural Engineering may not get involveddirectly in overseas assignments our society should take the initiative in assisting CIDA tolocate and recruit agricultural engineers. Canadians have an excellent reputation around theworld as helpful, dedicated people. We should have nodifficulty in carrying our share of theload if several of the obstacles mentioned can be overcome.

Canadian Agricultural Engineering publishes papers covering the general field ofAgricultural Engineering that fit into one of the following classifications: 1) a scientificpaper based on original research; 2) a technical paper based ondesign, development, testing,or analysis of machines, equipment, structures, processes, or practice; 3) a general paper oneducation relative to curricula and philosophy or trends in science, on a survey or investigation of somephase of research or research methods,or on extension or extension methods.The Editoral Board may also publish abstracts of papers published elsewhereand interestingnews items of members or developments in Agricultural Engineering.

Manuscripts for publication should be submitted to the Chairman of the EditorialBoard. The papers must be originalsand must not have been published elsewhere or copyrighted. The author, not the CSAE, is responsible for opinions expressed. Informationpublished in Canadian Agricultural Engineering may bequoted in whole or inpart providedthat credit is given to the author and to the journal. Information on page, reprint, and othercharges may be obtained from members of the Board.

NOTES TO CONTRIBUTORS

The Editorial Board will assess suit

ability and essential detail of paperssubmitted for publication in CanadaAgricultural Engineering. One or morereviewers will be used. Their comments

and suggestions will be compiled and submitted to the author. The review willensure that:

1. A research paper does represent apiece of research carried to a well-defined stage of advancement and thatthe conclusions are adequately supported by the experimental results.

2. A technical paper represents a clear,concise, and factual outline and interpretation of the development, design,test, or analysis under considerationand that it is a contribution in the

field of agricultural engineering.

3. A general paper on education, research, or extension is pertinent tomajor changes in curricula, research, orextension or to forward-looking developments in these areas.

MANUSCRIPT

The manuscript should be typeddouble-spaced on paper 8-1/2 x 11 in.(21.6 x 27.9 cm), with margins not lessthan 1-1/4 in. (3.3 cm). The first pageshould contain the title, author's nameand address, and any necessary footnotes.Tables and captions for illustrationsshould be on separate pages placed afterthe text. Manuscript paper with numbered lines is preferred. The original andtwo copies are required.

The title of the paper should be capitalized and centred on the page. If thereis only one author, centre the name andaddress under the title. If there are two or

more authors, space names and addressesequally under the title. Use lower caseexcept for the first letter of major words.Do not use abbreviations in the address.If the author is a member of the Society,designate as Member CSAE.

ORGANIZATION

The paper should be organized to conform with present Journal practice. Research and technical papers must includea short Summary section of about 200words.

Major headings — Centre on the pagewith all words in capital letters.

Subheadings - Start at left-hand margin, capitalize first letter of major words.

Sub-subheadings - Start at left-handmargin, in lower case except first letter offirst word, and underline.

Technical and detailed information

should be included in only one fashion —by description, table, graph, chart, orphotograph.

References

List references alphabetically byauthors at the end. Include year of publication, title in lower case except firstletter of first word, and source, withvolume and page numbers where applicable. Names of periodicals should beabbreviated in the form given in eitherthe List of Periodicals Abstracted byChemical Abstracts or the AmericanStandard for Periodical Title Abbreviations. Material in press, with the name ofthe journal, may be used as a reference.Private communications and reports ornumbered papers not yet accepted forpublication should be referred to in parentheses in the text or in a footnote.

Designate footnotes by lower-case lettersin alphabetical order using superscriptletters in the text. References in the

manuscript should be designated byarabic numerals in parentheses.

Tables

Designate tables at the top by tablenumber (Roman numerals) and title, allin capital letters. All headings and otherinformation in tables are to be in lower

case except first letter of first word. Keepthe table compact and place it across thepage wherever possible. Do not use vertical lines.

Measurements

Use the metric system in the textwhere practical or list metric equivalentsin parentheses after English units. Useonly one system in tables, charts, orgraphs.

Equations

Equations and formulas must be set upclearly. Use capitals for symbols as much

as possible and lower case for superscriptsand subscripts. Greek and other characters should be identified clearly. Equations should be numbered on the right-hand margin in large numbers and in linewith the centre of the equation.

Abbreviations

Typical phrases should be abbreviated(e.g., rpm, cps, hp, pto). They should betyped in lower case without periods.Abbreviate units of measures only whenused with numerals. Do not use abbreviations in the title or the summary of apaper. Normally, numbers less than 10should be spelled out, e.g., six.

Paragraphs

If paragraphs are to be numbered, designate by arabic numerals. Designate subparagraphs by lower case letters in parentheses.

ILLUSTRATIONS

An illustration or a group of themshould be planned to fit, after reduction,into a space equal in width to that occupied on the journal page by onecolumn (preferred) or two or threecolumns if necessary. The original shouldnot be more than three times the size ofthe final reproduction. For identificationthe figure number, author's name, andpaper title should be written lightly in thelower left corner of a photograph. Use asoft lead pencil. Photographs should beprinted on glossy paper with strong contrasts approximately 5 x 7 in. (12.7 x17.8 cm) in size. One set is required foreach copy of the paper.

Line drawings

Make line drawings with india ink onplain or blue-lined paper or other suitablematerial. Letters, numerals, labels, andaxis captions should be made in capitalsize with a lettering guide (not a typewriter). They should be large enough thatthe smallest character will not be less

than 1 mm high when reduced. Type thefigure numbers and captions on a separatepage. One set of clear copies is requiredwith each copy of the paper. The originaldrawings must be provided when thepaper is accepted for printing.
