Grant’s gazelle is one of the prettiest of the large 
group of gazelles. It occurs in herds of several dozen 
and prefers the more open stretches. The beautiful, 
lyrate, heavily ridged horns of the male, his proud 
carriage and stately demeanor among the herd, con¬ 
tribute to his remarkable appearance. 
between bushbuck and reedbuck is that both 
can be approached often at short distances. 
Nothing more graceful can be imagined than 
the picture of their sleek, lithe forms speeding 
over the high grass of the hills, where after 
the first few bounds they dexterously find 
means to disappear as by enchantment. 
On the park lands and invading the forest 
roam small herds of buffalo (N yncerus caffer 
radcliffei ), but though we followed their spoor 
eagerly for many a weary mile, we never man¬ 
aged to catch sight of them. It gave us, how¬ 
ever, an opportunity to see the luxuriant vege¬ 
tation, truly tropical in its profusion, the tree- 
trunks often heavily covered with showy air- 
plants, or epiphytes. Unusually great numbers 
of the lovely large flowers of the white orchid 
(Angraecum ) enlivened the scene. 
One night an Askari spied a dark form mov¬ 
ing about and, shooting, secured a wild bush 
pig ( Potamochoerus ) which for some reason 
or other had invaded our camp. An inhabitant 
of the bush country of the lower level, it is 
rarely seen during the day except in a great 
hurry seeking shelter when accidentally routed 
from cover. This is not open country suiting 
the lion, but rather owned by the leopard and 
a variety of small carnivores such as genets, 
civets, and mongooses. The streams, so our 
native guide claimed, harbor otters. There is 
the usual variety of the more common smaller 
rodents. Hares abound along the margins of 
the woods in the grass and gambol about to¬ 
wards dusk, or also after rains, behaving much 
like their cousins in other lands. They proved 
to be equally delicate in flavor. At night the 
peculiar barking of the Dendrohyrax lulled us 
to sleep. These little tree hyraxes are strictly 
arboreal and highly prized by the natives, for 
the heavily furred skins, rudely tanned but well 
sewed together in narrow oblongs, serve as long 
cloaks for the notables of the tribes. Though 
simple, these garments fall in imposing lines 
from the broad bronzy shoulders, adding much 
to the stately mien of the chieftains. 
Before leaving our first camp we discovered 
two new bird forms, described by Ldnnberg 2 
as a new white eye ( Zosterops bayeri), which 
differs in many respects from its Elgon relative, 
and a dark hawk ( Astur tachiro tenebrosus). 
On reaching part of the Nandi escarpment at 
over 9,000 feet true mountain forest appears. 
Stately groves of juniper ( Juniperus procerus ), 
which here attains 109 to 130 feet in height 
and a diameter of over three feet, represent part 
of the most valuable African timber. Clusters 
of bearded lichen form delicate draperies and 
underfoot grow many flowers familiar to more 
northern climes. The temperature is delight¬ 
fully cool, averaging about 50° F. during the 
day.

The impala attains particularly large hor.ns in the 
drier region north of Lake Baringo. It is always met 
with in the neighborhood of water. When suddenly 
alarmed the impala offers an exhibition of high jump¬ 
ing, ffeetness, and grace hardly to be equalled.
