-eled rock debris. It was rough going all night, but it had one redeeming feature: it was practically straight. In consequence of that we got to the mouth of the Sew at 3.15. It was rather horrifying to have to leave that limpid stream and climb about 300 feet to Willis's camp on the tip-top of the hill. From that was reached in 15 minutes. As we came up towards the Sew I noticed in the little stream crossed for time to time pebbles of rounded sandstone, rounded quartzite etc., obviously remnants of the same old conglomerate I have repeatedly recorded. Now I find this ridge capped with it. Also the ridge falls flat once towards the south. My interpretation is that this range (which turns the Palmsi westwards) was up-faulted and that at this end the cap of conglomerate which lay over the limestone has not been completely eroded away. We may even find traces of it on the approach slopes of blücher. Just on top of the hill we came through a brush garden and a brush house, but all deserted (temporarily at least). There are mosquitoes here, but thank goodness no stingers here. I suppose the sand flies will be thick this. Barometer (at 5.30 pm) 210 meters. Tuesday, July 7th: I didn't miss last night that for a scene of peace looks along the trail the great white landslide of Blücher can be seen. It bears 20° east of N. (approx.). Barometric reading (6.30 am) 180 mts. A good night with only one shower. Clear today. No mosquitoes were out in force as I feared. We got away at 8.30 + passed Healy's camp at 9.30, his route here high on ridge + not much conglomerate. Down to Sew 9.45 and then up its left bank (some pretty rough too to the ford at 10.45. It was only knee-deep. Followed sewer brook (Barometer crossing 120 m.)
