Bujuku Valley. — Eeturn of the Ex]iedition. 



Dr. Cavalli found plenty of occupation, and was busy for 

 several hours every day with the sick people who came from 

 far and near, supported or carried with loving care bv their 

 relations or friends. While undergoing trifling operations they 

 would scream and weep, and immediately after laugh like 

 children. 



Commander Cao^ni undertook a series of maonetic observa- 

 tions. Dr. Roccati made ijeoloo^ical and mineraloo^ical excursions 

 in the neighbourhood. One of these took him to the little 

 lake above Nakitawa where the Mahoma Valley opens into 

 the Mobuku Valley. This lakelet had been observed by 

 Moore, Johnston, Dawe, etc. Mr. Freshfield calls it Lake 

 Kobokora, but from all accounts it would seem that no one 

 had yet actually reached it. To arrive thither from Nakitawa, 

 Roccati had to pass through virgin forest without any track, 

 while the Bakonjos cut the way with axes through bamboos, 

 lianas and heaths. There were moraine ridges to cross, through 

 an midergrowth so dense that in many places they actually 

 walked upon the thickets, on an elastic cushion of branches and 

 twigs several feet deep. Now and again, one of the Bakonjo 

 guides would climb a tree to get his bearings. 



Near to a fallen trunk they found traces of an old camp 

 fire, a bit of newspaper and a sardine tin, no doubtful sign of 

 the passage of a preceding explorer, possibly Dr. WoUaston or 

 some other member of the British Museum Expedition. From 

 this point they reached the lakelet in one hour. It is plainly 

 a glacial lake, oval in .shape, and miming from south-east to 

 north-west, with steep shores and surrounded by a narrow strip 

 of nnul, beyond which the deep water begins at once. There 

 was fog round about, and complete silence, with no sign of 

 animal life. Dr. Roccati collected plants and zoological
