APPENDIX C 
The following notes were made by Loring in East Africa: 
Alpine Hyrax (Procavia mackinderi). On Mount Kenia, at altitudes between 
12,000 and 15,000 feet, we found these animals common wherever pro¬ 
tective rocks occurred. Under the shelving' rocks were great heaps of 
their droppings ; and in the places where for centuries they had sunned 
themselves the stone was stained and worn smooth. At all times of the 
day, but more frequently after the sun had risen, they could be seen 
singly, in pairs, and in families, perched on the peaks. At our highest 
camp (14,700 feet), where, on September 22, more than half an inch 
of ice formed in buckets of water outside the tent, they were often 
heard. They emit a variety of chatters, whistles, and catlike squalls 
that cannot be described in print, and we found them very noisy. 
Whenever they saw anyone approaching they always sounded some note 
of alarm, and frequently continued to harangue the intruder until he had 
approached so close that they took fright and disappeared in the rocks, 
or until he had passed. All along the base of cliffs, and leading from 
one mass of rocks to another, they made well-worn trails through the 
grass. At this time of the year many young ones, about one-third 
grown, were seen and taken. 
Kenia Tree Hyrax {Procavia crawshayi). From the time that we reached 
the edge of the forest belt (altitude 7.,000), on Mount Kenia, we heard 
these tree dassies every night, and at all camps to an altitude of 
10,700 feet they were common. I once heard one on a bright afternoon 
about four o’clock, and on a second occasion another about two hours 
before sundown. Although I searched diligently on the ground for run¬ 
ways and for suitable places to set traps, no such place was found. In a 
large yew-tree that had split and divided fifteen feet from the ground I 
found a bed or bulky platform of dried leaves and moss of Nature^s 
manufacture. On the top of this some animal had placed a few dried 
green leaves. In this bed I set a steel trap, and carefully covered it, 
and on the second night (October 14) captured a dassie containing a 
foetus almost mature. We were informed by our “ boys ” that these 
animals inhabited hollow stumps and logs, as well as the foliage of the 
live trees, but we found no signs that proved it, although, judging from 
the din at night, dassies were abundant everywhere in the forests. 
At evening, about an hour after darkness had fully settled, a dassie 
would call, and in a few seconds dassies were answering from all around, 
and the din continued for half an hour or an hour. The note began with 
a series of deep, froglike croaks, that gradually gave way to a series of 
shrill, tremulous screams, at times resembling the squealing of a pig, and 
again the cries of a child. It was a far-reaching sound, and always came
