Bujuku Valley.—Return of the Expedition. 
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 by their 
relations or friends. While undergoing trifling operations they 
would scream and weep, and immediately after laugh like 
children. 
Commander Cagni undertook a series of magnetic observa- 
tions. Dr. Roccati made geological and mineralogical 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 undergrowth 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. Wollaston 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 running from south-east to 
north-west, with steep shores and surrounded by a narrow strip 
of mud, 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
