“ Following up Sandy Creek, from its junction with the Albert River to Mount 
Tambourine, brown and yellow sandstone, with here and there shales with streaks of 
coal, occur. Mount Tambourine itself consists of leucitic basalt, overlying the Coal 
Measures sandstone. At the head of this creek a fine section of this basalt is seen, 
where the water, falling from a height of about one hundred feet, has made a cutting 
through it. I was informed that the outcrop of a thick seam of coal is visible in 
Flagstone Creek, twenty miles south of Beenleigh.” 
In his “ Report on the Albert and Logan district,” * Mr. Rands added the follow- 
ing notes : — 
“ The boundary between the Ipswich beds and the schists runs in a north-north- 
westerly direction from the heads of Nerang Creek to Mount Tambourine ; it passes 
under the basalt of that mountain, and then continues in the same direction, running 
between Sandy and Cedar Creeks, and crossing the Albert River about a mile above its 
junction with Cedar Creek. It continues on in the same direction for about sis miles, 
and then bends to the north, crossing the Railway Line and the Logan River near the 
village of Waterford, From thence it runs in a north-westerly direction to Kingston 
Railway Station, and then in a north-easterly direction to Mount Cotton, from which 
place it runs in a south-easterly direction to Alberton and Agestou. 
“ The beds consist of a series of sandstones, shales, and clays, with seams of coal. 
The beds dip generally at a low angle ; the direction and amount of the dip in various 
places is shown on the map. 
“ At Ageston the country is covered with alluvial deposits ; coal was met with 
below the alluvium, in a borehole on Mr. W. H. Couldery’s property, in Selection No. 2. 
“ In my Report on the Beenleigh District, 1887, I described these beds and the 
outcrops of coal that occur from Tambourine Mountain, as far north as Shailer’s 
Selection, Ko. 261. 
“ Hearing that Mr. Watt had opened up another seam of coal, I revisited his 
Selection No. 11. A drive sixteen feet long has been put in on a scam of coal which 
lies immediately beneath the freestone mentioned in my last Report. The section seen 
here is : —

Shale (coaly). 
The seam is, therefore, three feet three and a half inches thick, including seven 
inches of bands. Unless these bands which are distributed throughout the seam thin 
out, the coal will be of no commercial value. The dip of the strata here is south-west
