FLORA OF TIBET OR HIGH ASIA, 151 
we find the note: “The ground on which we have camped is one 
big bed of fragrant, light blue flowers (Meroula sikkimensis), and 
the grass is so long that it makes a soft bed for us.” The change 
in climate and flora is already perceptible in this longitude. 
Mr. Rockhill’s mean temperatures are reproduced in our 
chapter on climate. It may be worth while pointing out that 
in his Table of Latitudes and Altitudes (‘J ourney through 
Mongolia and Tibet,’ pp. 386-395), he makes some interesting 
comparisons with the altitudes and geographical names obtained 
by other travellers. 
From August 11th, approximately in 94° and 32°, Rockhill 
followed Bower and Thorold’s eastward route, and the differences 
in altitudes and geographical names, as given by the former, are 
considerable.

37°. 1895. 
Travelled overland by Constantinople, Tiflis, and Samarkand, 
across the Tian Shan through the Terek Pass (12,700 ft.) in 
midwinter, onward to Kashgar. Thence to Yarkand, which they 
left on Feb. 4th, 1895, for Khotan, Keria, and Cherchen (85° 
35’ and 38° 10'), where they arrived on March 19th; and it was 
not till May 15th that they actually crossed the Arka Tag into 
Tibet. Their route thence was south-east by east toward Lhasa, 
which was really the goal of their journey. The pass, though 
not steep, was high and Jong and cost them the lives of five or 
six donkeys and a couple of horses. They were now on the 
Tibetan Plateau, with lakes and low mountains to the south, as 
far as could be seen, and to the north the high range of the 
Arka Tag, with fine glaciers and snowfields. Two peaks, 
towering above their neighbours, were measured, and estimated 
to be 25,340 ft. high. Volcanic country was next traversed, 
where vegetation and fresh water were both scarce. One night 
all their sheep were killed by wolves; and, owing to the great 
altitude and scarcity of food, their baggage animals died at an 
appalling rate and they had to walk. On June 26th (88 le 
and 33° 12') they had the first rain since leaving the Black Sea 
in November, and saw the first men since leaving Cherchen in 
April. Continued mortality of their animals compelled them to 
abandon the greater portion of their stores. They passed along 
the east side of the lake, called by Captain Bower Garing Cho
