SUMMARY:
From Chianang the diarist reports illness among companions, a reconnaissance with Kunio toward Chubumbu La with notable rhododendrons and Nomocharis, persistent rain, and route details. Plans to attempt the Chubumbu La despite local advice are noted, along with Brahminy Ducks near Lanyong; subsequent halts include botanical collecting and bird observations, before proceeding up-valley toward a pass.

...vomiting everything he tried to swallow. He has no strength today at all. I went with Kunio towards Chubumbu La, which is about 6 miles from here, and has not too much snow on it to be crossed. There was nothing to be seen till we reached the head of the valley, then rhododendrons in profusion, P. pauliana all over the place, Nomocharis souliei the best of all, masses of Rhod. aff. repens, in full flower.
3rd June. CAMP CHIANANG. 5 miles. B.P. 189.0° Temp. 50° Time 11:30 am. Ht. approx. 12929'.
Rained most of the night and all today without a stop. Path follows the left bank for 2 miles, then crosses by a foot bridge to right bank. At mile 3 a side valley from the Chubumbu La is reached and crossed. The Chubumbu La lies at a bearing of 162° Magnetic and from here is about 4 miles distant. Follow up this valley left bank for ½ mile, then turn up a side valley. Ascent fairly steep for 1½ miles to a plateau, where there are 3-4 houses, where yaks are grazed in summer. Very swampy ground. We saw nothing at all today, as Lin was not yet too fit and Tsungpen only just able to come up, we did nothing today, but sat in camp and changed flowers. I'm afraid this valley is not as good as I had hoped: we are still too early. So I remain only two days and then go to the Chubumbu La for a day, to see if I can get across. It does not look impossible, though the locals say it is, and will remain so for another 2 months or more, when the Lhopas will come over. There are Brahminy Duck near Lanyong, and I saw they have their young one now and quite big.
4th June. Halt. Chianang. Fine intervals with a little sun up till 12:00 noon, then rain all day. Went up to the South, and had a fairly good day. Rhod. repens is abundant, but not above 14000'. With it were P. harrisii, and P. valentiniana 3953. This must cover the hillside, but is hardly in flower yet. Just as at Tsari Chikchar, it comes just after P. harrisii. First one gets a blue violet hillside, which is then turned into a deep velvety crimson one. P. vernicosa 3951, is here about half blue and half white. Saw a good many Grandala coelicolor above, some rubythroats; the latter is not the Yunnan bird.
Diapensia himalaica 3949, Potentilla leucanota 3950 - Bell common, Pot. stenophylla 3956, Pot. microphylla 3957 & 41, Pedicularis formis 3959.
5th June. Halt Chianang. Rain early at night, but a fine day till 2:00 pm, then thunder and rain and snow on the hills. Cleared 2 hours later. Went up the valley, past two more yak grazing grounds to a pass,
