Russia. — In the mountain chain of Peter the Great, Boukhara, 

 two glaciers show an advance since 1899, one of them as much 

 as 64 meters. One in the Tian-Chan shows a retreat since 

 1892. 



Caucasus. — Many glaciers have been visited and named; the 

 Bartui has steadily been retreating ; the retreat amounted to 30 meters 

 in 1900-1, 12 meters in 1902-3, 13.5 meters in 1903-4. The glaciers 

 of the Caucasus seem to be in general retreat.^ 



British Columbia and Alberta. — The Illecillewaet glacier continues 

 to retreat, but much more slowly; it lost but 2 feet 6 inches between 

 1905 and 1906, though there has been a general shrinking in the volume 

 of the ice. The tongue of the Asulkan glacier is slowly melting away 

 under the moraine.^ 



South America. — A short description of the glaciers of Poto, just 

 north of Lake Titicaca, Peru, has been given by Otto F. Pfordte.^ 

 The San Francisco glacier has high terminal moraines, but the present 

 end has not varied much since the Spanish occupation, as shown by the 

 ruins of houses at the foot of the cliff, where the glacier now ends. 

 Old observations and traditions of the natives indicate that the snow- 

 line is gradually receding in this part of the Andes, which accounts 

 for the gradual lowering of the lakes. Mr. Bandelier,4 referring to 

 this same general neighborhood, states that the glaciers of the BoHvian 

 Andes have been in slow retrocession for a number of years. 



Central Africa. — The Mubuhu glacier on the eastern slopes of 

 Ruwenzori is apparently in retreat. An old moraine overgrown with 

 vegetation may be recognized some 500 meters in advance of the 

 existing tongue of the glacier, and from the appearance of the rocks 

 nearby it would seem that a slow retreat is now in progress (1905). 

 Morainic lakes have been observed on the western slope below the 

 limits of the present glaciers by Dr. Stuhlmann."
