lower levels auriferous iron and copper pyrites begin to be met with, and it is possible 
that deposits concentrated in reefs will be discovered. The Neck is of considerable 
extent, covering nearly 200 acres, and is auriferous from its northern cud to its south- 
western extremity (Wallaby Point). It is singular that in the adjacent twin neck, 
Mount Mawe, the existence of payable gold- has not yet been proved. 
The total yield of Charters Towers and the Cape up to 31st December, 1890, is 
estimated at 2,078,531 oz. How much of this came from the Cape it is now impossible 
to say. During lato years the amount has been comparatively insignificant, but it is 
probable that for the six or seven years prior to the opening of Charters Towers (in 
1872) it was of considerable importance.

GILBERT ANn WOOLGAH V.OIA) FIELDS. 
These fields, although coterminous with the Etheridge, differ from it essentially 
in their geological characteristics. The divide between Caledonia Creek (one of the 
heads of the Delaney Eiver, a tributary of the Etheridge) and the Eobertson Biver (a 
tributary of the Gilbert) is dotted over with little fragmentary tablelands of Desert Sand- 
stone. The latter formation, as mapped by the late Mr. Eichard Daintree, occupies 
considerable areas in the Newcastle and Gregory Eanges, and between Agate Creek and 
the Percy Eiver. The conglomerate beds of the formation are rich in agates, topazes, 
garnets, and other precious stones, including, it is said, rubies, sapphij-es, and diamonds.* 
Another belt of the Desert Kandstone makes its appearance at the heads of the Woolgar, 
Mr. Warden Samwell in Report of the Department of Mines- for 1873.
