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 protective 
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 the 22d 
of September 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 
cat-like squalls that cannot be described in print, and we found them very noisy. 
Whenever they saw any one approaching they always sounded some note of 
alarm, and frequently continued to harangue the intruder until he had ap¬ 
proached 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 runways, 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 
frog-like 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 from the large forest trees. Often 
the cries were directly over our heads and at a time when the porters were sing-
