Maria, I recall the article you're looking for "Arrows of Melanesia" by David Skinner, and actually am surprised, it doesn;t seem that long ago
I recall it was an incredible article, virtually a book within a magnificently published magazine, I used to subscribe to it it seems lifetimes ago.
Online you can find "Tribal Arts" magazine and you can order back issues, I checked and it is available, Summer 2000, #23 @25.00 and apparantly in stock.
Out of all the issues I had, that one impressed me the most for the incredible detail and volume, and I honestly never realized arrows were this long!
I would gladly help with my copy but as I am on the road wont be able to access for some time. Hope this info will help.
All best regards,
Jim
