gathering itself to spring at him. 
Thence they went to Nakuru, where Kermit killed two 
Neuman’s hartebeest. They were scarce and wild, and 
Kermit obtained his two animals by long shots after fol¬ 
lowing them for hours; following them until, as he ex¬ 
pressed it, they got used to him, became a little less quick 
to leave, and gave him his chance. 
While on this trip Kermit passed his twentieth birth¬ 
day. While still nineteen he had killed all the kinds of 
African dangerous game—lion, leopard, elephant, buffalo, 
and rhino. 
Heller also rejoined us, entirely recovered. He had 
visited Mearns and Loring at their camp high up on Mount 
Kenia, where they had made a thoroughly biological sur¬ 
vey of the mountain. He had gone to the line of perpetual 
snow, where the rock peak rises abruptly from the swelling 
downs, and had camped near a little glacial lake whose waters 
froze every night. The zones of plant and animal life were 
well marked; but there are some curious differences between 
the zones on these equatorial African snow mountains and 
those on similar mountains in the northern hemisphere, 
especially America. In the high mountains of North Amer¬ 
ica the mammals are apt to be, at least in part, of totally 
different kinds from those found in the adjacent warm 
or hot plains, because they represent a fauna which was 
once spread over the land, but which has retreated north¬ 
ward, leaving faunal islands on the summits of the taller 
mountains. In this part of Africa, however, there has been 
no faunal retreat of this type, no survivals on the peaks of 
an ancient fauna which in the plains and valleys has been
