No 606 might have some value for vitrified ware, but shrinkage is large. It is a dirty white clay 
with a little grit. 
No. 607 would be suitable for making common brick. It is a red clay, was tested as a pigment, and 
found unsuitable for that purpose. 
On the north side of Mount Wellington, and about 12 chains from the top, 
there is an outcrop of limonite (see assay 599). It is a few inches thick, and 
d0es not appear to cover any great area, but without trenching and shallow 
trial pit3 its extent is uncertain. This limonite may result from the decom¬ 
position of the basalt, or it may have segregated from the Tertiary mottled 
clays that cover so much of the surface of the island.
