The silicates of lime and magnesia prevail in this soil. 
The dark red subsoil appears to be mixed with the surface. 
Memorandum accompagying the soil Vineyard on a fat—flat mostly formed 
of debris washed down by the creek from the Table mountains (voleanic.) It 
is surrounded by hills formed by lava composed of white chalk, red and yellow 
ochre, &c., iron rock, sandstone, &c. The flat seems to ‘rest on a decaying 
iron ledge. Soil varies much; sample hardly a fair one.’
