of May to Pindaree and over the Piudaree or Trail's Pass (17,950 

 E. F. high) to Milum, crossing at the Pass the high snowy range of 

 Trisoal and Nanda Devi. 



During the month of June, we were both of us engaged at Milum, 

 and at several elevated places and glaciers at some distance from it, 

 with a series of Physical and Geological observations. "We left Milum 

 on the 6th of July and went by the Uta Dhura (17,670 E. F. high) 

 and Kyangur (17,300 E. F.) Passes into the Thibetan Province of 

 Gwarikhorsum ; all the baggage which was not absolutely wanted 

 being sent round by Hoti and Niti to Badrinath. After many 

 negociations with the Lhassa Officials forming the Government of 

 these parts of Thibet, we made it possible to go as far as the Sutlej, 

 and afterwards as far as the Chako La Pass (17,350 E. F. high) which 

 lies in the range separating the Sutlej from the Indus, where we 

 arrived on the 25th of July. 



"We succeeded in reaching from thence, between the 26th and 28th, 

 the valley of the Upper Indus, near Gartok, which had only once 

 before been visited by Europeans, i. e. in 1812, by Moorcroft and 

 Hearsay. 



From two stations, one near the Indus, the other at a fine isolated 

 peak, Gunshankoerr, (29th July, 19,640 E. F. high) not far from 

 Chako La, we had an opportunity of taking several series of angles 

 with a Theodolite, which will serve to lay down the Mountain 

 systems round the origin of the Indus and North of it. 



From Chako La we proceeded by Gyungal, Daba and Mangnang to 

 the foot of the great glacier stretching out to the northward into 

 Thibet from the high peak Ibi Gamin (called also £ametinrite), 

 where we arrived on the 13th of August. 



After having explained the merely scientific nature of our re- 

 searches and made the necessary arrangements, we met with no 

 further trouble in any way, and enjoyed throughout our journey 

 quite a friendly intercourse with the inhabitants. 



We started from this point on the 16th of August, to examine 

 the structure and dimensions of the Ibi Gamin glaciers, with the 

 intention also of attempting to ascend as high as possible on the 

 flanks of the Ibi Gamin.
