inland. Naval planes went out to see the Bantam and returned during the day. July 12th. Completed packing three months stores to be flown to Habbema. Collected in afternoon a common Dipterocarp fruiting in the near by rain-forest #9000. Among other things collected were Freycinetia 9004, a fine species with orange bracts and the fifth or sixth species for the locality. Put together one of my portable ovens and packed it with best insulating mixture of asbestos and pipeclay in preparation for a test with the Dyaks tomorrow. July 13th. My Dyak, Ung-Au, appointed to look after the collapsable oven, made a good job of i it: but my regular boy in charge of drying specimens burnt out two water-jacket ovens during the day. July 14th. Packing equipment and supplies for Habbema. July 15th. Trial landing of aeroplane on Lake Habbema: this the critical day of the whole expedition. The Guba behaved splendidly. From her performance Rogers says a pay-load of 2500 k. can be lifted from the lake. The clouds closed down just as th plane arrived at the lake at 7.30 AM, but having one edge of the lake in view, a blind landing was effected. A good anchorage, landing and camp site were found in the bay on the north side of the lake. Tests with a field radio (A.W.A.) set rigged on shore with antenna on a 15 foot tree proved very satisfactory. Un the return flight in the afternoon it was necessary to climb to 6000 m. to clear the clouds. K.P.M. mail steamer "Van Imhoff" arrived in the afternoon and left at 10 PM. She attempted to haul the Bantam off the reef on tomorrow morning's tide.
