L-21. P. S. I omitted to say that both the pups of yesterday were paid for with knives, and the sweet potatoes with tobacco. The same conglomeratic rock forms all the high ridges formed during yesterday's travel, and we are on it here too. It looks to me as though the east-west course of the Palms and Sen marked a fault. The limestone is of course under this present ridge and down at the Palms has been fairly deeply cut by the river. Put out no traps last night or the night before but camped nothing in them. Evening. - I well, what a day this has been! First of all everything I said yesterday must be modified because we were not at the 610 mile corner at all. We got away at 8.30 after the rainy night. Much of the road followed the river closely and consequently was (and is) probably subject to floods. About 11.30 we came out of the shingle once more for a while and found ourselves dry wet (of all things), but gradually wore around to north again. We kept getting glimpses of not Donaldson as we got to peer out of the first clear suitable place on the river. Just about then passed a hut house (new) but no people were to be seen. House on low hill. Quite suddenly, we reached a reef of limestone with strikes about NW-SE which we climbed over in a couple of minutes and a quarter.
