Soils of the South-Western Districts of the Cape Colony. 137 
I have referred to these analyses of Dr. Hahn’s because the 
granite soils being, as it were, nearer home and their investiga- 
tion occupying the earlier position in point of time, they form a 
convenient basis with which to compare later work. 
For obvious reasons it will not be advisable to take the soils 
collected and analysed by us in their chronological order. Eighteen 
samples were collected from the granite formation which extends 
between St. Helena Bay and Koeberg. It was, however, thought 
that, as the granitic soils of the Cape Peninsula had already been 
to some extent explored, it would be advisable to go farther afield 
and enter upon a formation regarding whose soils very little, if any- 
thing, had up till then been learnt—from a chemical standpoint, of 
course. Hence, even while collecting soils from this granitic area, 
our aim was to confine ourselves as much as possible to the alluvial 
soils derived from the clay state lying to the east of the granite. It 
may, however, be well to give a complete list of the soils collected 
from the granite formation. Together with the results of the 
analytical examination they will be found comprised in the fol- 
lowing table :—
