In the Volcanic Region 121 
inch or so long can be found in the lower. On the other hand 
clawed toads (Xenofus spec.) are uncommonly numerous in both 
lakes; they ser\^e the people as food and are to be met with 
in large quantities in all the huts, packed into baskets, alive 
and dead. I found, too, a heap of wooden staves, about half 
a metre in length, between which the toads were squeezed to 
dry them, lying under one another, parallel, in twenties. Near 
by I found a busy hive of snare-basket makers fashioning pots 
for catching prawns. These little crayfish (a species of caridind) 
are found in large numbers in the lower lake, and the lake- 
dwellers have a great partiality for them. Lake Luhondo 
abounds in reeds and rushes, and its surface is enlivened by a 
large variety of ducks. 
As we stayed there for several days we had some time to 
devote to ethnographical study, and were able to supplement 
our Ruanda collection very considerably. 
The inhabitants on the borders of both lakes are of a 
fractious disposition and give the Residency a good deal of 
trouble. The Resident, therefore, has to keep a watchful eye on 
this district, and has often been compelled to resort to energetic 
measures in order to maintain the authority which it is imperative 
to uphold. 
The boats used on the lake are built very low, and are very 
fragile, with practically no gunwale. Great care is therefore 
necessary to retain the balance. Raven met with a very 
unpleasant experience in this respect. Whilst shooting at a 
duck he lost his equilibrium, and capsized with his gun, 
cartridges and oarsmen. His rain-cloak, however, which was 
made of “ continental ” balloon material, kept him afloat on 
the water, and blew out like a bell. The rifle, which lay softly 
embedded in the slimy bottom, was brought to light from the 
watery depths with miraculous swiftness by the skilful diving 
of his oarsmen. 
Unfortunately Grawert took his leave of us here in order 
to return to Usambura on receiving news of the illness of one 
of his officers. It was with deep regret that we saw him depart.
