it may be noticed, from the first paragraph above quoted, that Mr. Woods appears to 
have confounded elevation with disturbance, or at least to have considered the one as 
necessarily accompanying the other. I fear that it will continue “ to be the custom” to 
attribute such phenomena as Mr. Woods referred to, to elevation and subsequent 
denudation. So far from “such stupendous denudation on horizontal strata ” batSing 
comprehension, the earth is so full of examples of the same kind, that they may bo said 
to be paid of the everyday experience of every geologist. It is only necessary to 
instance the Cafions of Colorado, the Felseiistadt in the Eiesengebirge and the Blue 
Mountains of New South Wales, and I venture to say that most of my readers can 
supply other instances from their own observation. 
The Tipper Group of the Cretaceous Eocks, or Desert Sandstone, was, until recently, 
regarded as almost unfossiliferous. Organic remains appear to have been first found in 
these strata in 1872, by Mr. Norman Taylor, at Battle Camp, near Cooktown. In 1885, 
Mr. Warden Samwell collected fossils from the Desert Sandstone at Croydon, and 
subsequently the Writer made further collections from the same district. In 1890, 
Mr. A. Gibb Maitland discovered fossils in the Desert Sandstone near Battle Camp 
Eange, on the Cooktown and Palmer Eailway. But even of more importance than these 
is the history of the Maryborough Beds, which, formerly regarded only as a portion of 
the great Cretaceous Series, are now known to occupy a higher position, representing 
the De.sert Sandstone of other parts of Queensland. The organic remains of the Desert 
Sandstone and Maryborough Bods, my Colleague says, “ partake in a great measure of 
the facies of the Eolling Downs Eormation, with an admixture of forms not hitherto 
recognised in the latter.” 
AGE OF THE DESEET SANDSTONE AND LIFE OF THE PERIOD. 
The following is my Colleague’s List of Fossils from this Formation. The 
different localities are denoted by initial letters, as follows : — 
True Blue Hill, Croydon, t; Bett’s Creek (Cape River), u; Alitohell River, 5IK ; Mount 
Angus, Croydon, A ; Maryborough, M ; Mullet Creek, MC ; Isis River, I ; the first four localities being in 
the Desert Sanilstone proper, and the last three in the Maryborough Beds.
