(63) two gallons of methylated spirits from Ebery & Walsh,Kieta.However, by such expediences as unwrapping birds three or four days old and reusing the cotton we have managed to put up everything taken and look forward to a good set of skins on our return to Arawa.During the month at Kupei over 600 skins were carried down to Mr.Esson's house. One large biscuit tin of material in formalin was also sent.The gen- tleman mentioned has been invaluable in his kind assistance.Besides boarding us for over five weeks while we were waiting for the France. The period of stay at Kupei was thirty-three days- Decem- ber 3I,1927 - February I,1928.We departed to spend a short period at Kaino Village on the latter date,a location at I300 feet which enabled us to complete the collection of the"lower zone"birds.The major portio of the work was done at the Kupei station.The goal set was 1000 skins. We took 6I2 from the higher camp.On January 3I the field book showed 49 different species.At this time we also took account of the follow- ing: IO rats(small Pacific) 2 bats 3 flying foxes In Solution I4 small cave bats I7 snakes 7 centipedes 3 iguanas 8 geckos 8 lizards 4 rats I fresh-water eel I nestling hornbill I thrush We lost track of frogs,insects,and snails,but estimate I50-200 frogs,I500 snails,and 1000 insects.All this stuff,brought by natives of various nearby places,some even I0 miles distant,reveals great variation.The total terrain represented in this department is something like 64 sq.miles. Both G.R.,and I have taken the aneroid up on several occa- sions and have marked certain elevations- 3000,3500,4000,5500,the last being the maximum(the trail goes to 5200).Based simply on rough ob- ervation while hunting I offer the following table as a general indi- cation of bird ranges educing what we have called"zones".Naturally the limit of the"zone"as estimated does not necessarily restrict a species entirly to that particular area,but judging simply from our hunting experience the 72 different species of birds taken may be thus classi- fied as to altitude(where to go to find the greatest number): (note: this table includes work done on Bougainville after Mr. Beck,Dr.Drowne,and G.R.,had left for America during which ad- ditional species were taken) 4000-5500 Thrush Redbreast Warbler 3500-5500 Yellow-leg ground Pigeon Black Hawk White-breasted Hawk Crested Pigeon 3000-5500 Mt.Thickhead Ashy Fantail Green Parrakeet Yellow-bib Dove Black-winged Pigeon Yellow-eyed Pigeon White-throated Pigeon
