334 EFFICIENT PREPARATION IN AMMUNITION AND ARMS. 
guns and two twenty-two caliber automatic rifles for small game 
and for amusement around camp. His shotgun ammunition was 
specially loaded for him and was in brass shells. The wads had 
been carefully waterproofed, and instead of the shell being merely 
crimped over the wad at the end, it had been cut into small flanges 
and bent over. The wad was covered with wax. This was to pre¬ 
vent swelling in the moist climate, which might affect paper shells. 
Colonel Roosevelt accepted an invitation to camp on the grounds 
of the Attenborough brothers on Rake Naivasha. The elder of the 
brothers is Captain Frederick, a retired British naval oflicer. The 
younger is H. T. Attenborough, who for twenty years was a resi¬

built a splendid European estate and home in the African mountains 
where they live like feudal lords of old. Their manor house is in 
the low mountains which fringe the southern shores of Lake Nai¬ 
vasha, while their estate runs down to the shores of the lake. 
ROOSEVELT SHOOTS A HIPPOPOTAMUS. 
The Attenboroughs live in a veritable Arabian Nights atmos¬ 
phere. They have built a lake of their own, in which they have

As Colonel Roosevelt was lacking a bull hippopotamus for his 
bag, the brothers insisted that he shoot one from their lake, the skin 
being added to the collection being shipped back to the Smithsonian 
Institute in Washington. 
The hippopotamus is, as the import of its name, river horse,’' 
implies, most aquatic in its habits. It generally prefers fresh water, 
but it is not at all averse to the sea, and will sometimes prefer salt 
water to fresh. It is an admirable swimmer and diver, and is able 
to remain below the surface for a considerable length of time. 
In common with the elephant, it possesses the power of sinking 
at will, which is the more extraordinary when the huge size of the 
animal is taken into consideration. Perhaps it may be enabled to 
contract itself by an exertion of the muscles whenever it desires to
