L. 18. P.B. mouth of the Black River. The sketch to the right shows the ground covered; we went up the west mouth of the Palmer and crossed through the eastern mouth to join the Black. Saw several gardens, one shelter when a canoe was tied below to the bank on the east arm of the Palmer. Some had pulling in places but enough gravel was uncovered to allow us to walk & have the log pull the dugout around. Picked up some very nice limestone fossils on the bars. No mammoth teeth at all at one corner of the combined Palmer-Black where it turns from E. to S. Large expanses of gravel exposed with the river winds a lagoon-like - a lovely spot (marked A on diagram). The arm of the Palmer up which we traveled is lined with gravel & sandbars first one side then the other, and growing in them quantities of wild sugar cane, an evening primrose, and a number of sedges. Going down the east arm of the Palmer towards the Black we hit a submerged boulder but no harm was done. The evening rain caught us before we could get back to camp. Wed. June 10. Not much rain last night - river low, nothing in traps. Took walks to S.E. along ridge crest. Found native shelter. No people however. This p.m. when boys were bringing airplane gas
