radio operator--now on £1700 per year pension. Was with 1921-22 expedition as radio man--also with government. Mr. Schneider says no danger of flooding our stores like the flood of '23 from rain--now dyke built. July 23rd. Another successful flight Habbema as per schedule. Yancey went in as observer and copilot and finds that the map is all wrong. The photographs which I developed last night however check with the map as do the others--but Rogers and R.A. insist the lake is elsewhere and the valleys run in different directions than those laid down on the map. Yancey now agrees to this. Careful checking--on my part-- shows that the in-land area does correlate very closely with the map but of course there is no correlationwith the Idenburg River which still R.A. and Rogers insist is in a different relation. Mixed. But Brass' and my data, which correlated closely, and which correlates with photographs was laid down on bearings supplied by Yancey and the scale was supplied by him. I'm discouraging natives from bringing in the same things over and over, as they have been doing. And tonight they brought in two young Lorriculus, barely able to fly--said to be taken from a hole in a tree. July 24th. Sunday. Captain Teerink returned to Hollandia. A successful flight and stopped at Idenburg to confer with Van Arken and to fly our route. They visited the native bridge of Grand Valley which Rogers found yesterday. July 25th. Ebeli came to Hollandia--picked up at Sentani after flight on schedule. Van Arken left for inland to receive food August 6th. No contact tonight at 5.30 or 8 as scheduled.
