Bougainville Is., South Coast - Buin District July 20-27 - 1929 The only extensive lowland littoral on Bougainville.Hills of approx. 1000-1500 feet close around Tenolai harbor(Sk point of the island).Thence westward around the southern and southwestern edge of the land(about 50 miles of coastline)- low,flat country reaches inland from 15 to 20 miles. It is swampy in many places,especially southwestward from the high moun- tains(Siwai & Banoni dists.).Numerous small rivers drain the southern wa- tershed of the Kronprinzen Gebirge.The land is covered with dense seconda vegetation everywhere,interspersed with great trees of several species;th smaller bush,generally thicker and more difficult to penetrate,is predom- nant:groves of small trees about 30 or 40 feet in height,brakes of wild cane along the river banks,and no grassland worthy of mention;native gar- dens in number,the heaviest bush usually being cleared to yield the best soil- apparently the farther inland the more fertile. All species taken during the visit to Buin represent this uniform hab- tat. (note:The local patrol officer,a man of considerable experience,describe a lake he had visited up in the mountains,which can be reached from the Buin coast in two or three days.No natives living near it(or anywhere on Bougainville at this elevation)- about 3500 feet or more.The place is sup- posed toq be the habitation of a tamburan(devil,hongoblin,ogre,etc.,) and is regared with superstition by the mountain natives.Mr.Ward estimated it to be about 7 miles long and one or two wide,regular in shape,and set in a sort of pocket formed by converging valleys and ravines.He viewed it from a commanding ridge;most of the sides were very steep to descend,rocky cliffs dropping sheer in some places around its marge.It looked to be heavy to the waters edge on all sides;no reeds or grassy marshland was discernible.This report is verified by Rev.Father J.B.Poncelet of the Marist Mission who is the only other white man who has seen it. The expedition was unable to make a camp here.)
