TIME AND CHANGE 
sumers really find out the superior quality of the 
Hawaiian product. 
From Mr. Aiken’s house one has a view of the 
great wall of mountains that form the western and 
older — older geologically —end of the island, 
in which lies the famous Iao Valley, which I have 
already described. We judge, from the much deeper 
marks of rain erosion, that this end of the island 
is vastly older than the butt end upon which Halea- 
kala is situated. Haleakala is eroded comparatively 
little. On all its huge northern slope there is only one 
considerable gash or gully, and this is probably not 
many thousand years old; but the northwestern end 
of the island is worn and carved in the most striking 
manner. Looking at it that morning, I compared 
it to my extended, relaxed hand, the northern end 
being gashed and grooved like the sunken spaces be- 
tween the fingers, while the southwest end, not more 
than ten miles distant, was only slightly grooved and 
more like the solid wrist and back hand. All the 
rains brought by the northeast trades fall upon the 
northeast end of the islands. The mountain-peaks 
on the end hold the clouds and strip them dry, so that 
little or no rain falls upon the south and southwest 
sides. This is true of all the islands. One end of 
each is arid and barren, while the other is wet and 
verdant. One of the smaller islands, Kahoolawe, I 
believe, dominated by Maui on the northeast, is said 
to be drying up and blowing away by inches.
