TIME AND CHANGE 
islands are famous — pretty, pearl-like little whorls 
living on the largest trees, and about the size of a 
chipping sparrow’s egg, with pointed ends, variously 
colored. There are more than two hundred species 
on the different islands, I think, each valley having 
varieties peculiar to itself, showing what a factor 
isolation is in the evolution of new species. The 
Governor and his wife, and a young man who had 
specialized in conchology, plucked them from nearly 
every bush and tree; but my eye, being untrained 
in this kind of work, was very slow in finding 
them. 
Coming down from these Hawaiian mountains 
is like coming out of a dripping tent of clouds into 
the clear, warm sunshine. The change is most de- 
lightful. Your clothing dries very quickly, and chil- 
liness gives place to genial warmth. And the pro- 
spects that open before you, the glimpses down 
into these deep, yellow-green, crater-like valleys, 
checkered with neat little Chinese farms, the pano- 
rama of the city and the sea unrolling as you come 
down, and always Diamond Head standing guard 
there to the east — how the vision of it all lingers 
in the memory! 
In climbing the heights, it was always a surprise 
to me to see the Pacific rise up as I rose, till it stood 
up like a great blue wall there against the horizon. 
A level plain unrolls in the same way as we mount 
above it, but it does not produce the same illusion
