On attempting to pass from the Lichting to the Lachen valley 
by the Donkia pass and the small portion of the upper Lachen 
valley which is in Tibet, the travellers found themselves again 
stopped by the Tibetans. After two or three days negotiation, a 
much higher official, the governor of Kambajong, arrived, and 
with much politeness said he was obliged to refuse to allow them 
to pass, as he had just received special orders on the subject from 
Jigatzi and Lhassa. They were, therefore, compelled again to 
descend to the hot Tista valley, and make 10 long marches in- 
stead of 2 short ones to reach Kongra Lama pass or Djo-kong- 
tong, the Tibetan frontier in the Lachen valley. Here they 
again met the Sfba of Kambajong, who had procured some Ovis 
ammon and goa skins, and 4 live Syrrhaptes Tibetanus for them. 
They obtained from him a little information concerning Tibet, 
the most interesting of which was the absolute prohibition of all 
imports of tea from Sikkim. 
Around Kongra Lama they obtained a few birds not elsewhere 
seen, amongst them a new Montifringilla. They left the pass on 
the 5th October and, marching back by the Tista valley, reached 
Darjiling again on the 20th. In conclusion, Mr. Blanford briefly 
described some of the traces of former glaciers which he had seen. 
None were noticed on the Chola range below 12000 feet elevation, 
but in the upper Tista valley glacial markings descended to be- 
tween 5000 and 6000 ft. He especially noticed the great mo- 
raines of the Laching and Lachen valleys, described by Hooker, 
and expressed an opinion that the plains of Phaling, four miles long 
by two miles broad, were entirely composed of moraine accumula- 
tions, probably derived from the great glacier which passed down 
the Lachen valley. 
Dr. Stoliczka said—he would not enter into the numerous details 
of observations made by Mr. Blanford on his interesting tour, but 
only allude to one or two points noticed by him. Referring to the 
difficulties which every traveller has at the present time to encoun- 
ter in crossing the Tibetan frontier, it would appear, asif the 
Europeans had, so to say, come into discredit with the Tibetans 
within the last 20 years. Some 380 or 40 years ago, the difficulties
