“ A little distance west-north-west from the outcrop in the creek a shaft had 
been sunk through sandstone, to a depth unknown to my informant, with the object ot 
meetingthe coal. The shaft had been abandoned some time, and I was unable to descend. 
“ In the section described above there is an absence of underclay or seat-eartli. 
The coal rests directly upon coarse grit. It would appear as though the coal had been 
formed in such a position as would allow of the access of sandy matter, ihe Ingli 
percentage of ash, as well as the gritty character of the base, gives credence tothis ymw. 
“following the windings of the creek for a mile or two down its course, sections 
show nothing but fine-grained argillaceous and micaceous sandstones, with modules ot 
ironstone and small pellets of coal. The beds roll about a good ea , u eir ip 
never measured more than from 5-7 degrees northwards. They rest upon a coarse sand- 
stone described* as occurring at the spot where Pucklcy Creek falls over a wall of 
granite 50 feet high. From this point to the railway the country is occupied by granite 
of the usual type. , , ,. . i „ 
“ About a mile below the Eailway Bridge a bed of coarse sandstone dips at a low 
angle down the creek ; it is seen to rest upon granite. 
“ It will be seen from the altitudes given that the A? elcome Valley beds occupy a 
position below those at the head of Puckley Creek. 
“ Per the purpose of comparison, the analyses made of the Desert Sandstone 
coals have been thrown into a tabular form. j -u ht t? t 
“The description of the localities from which the coals analysed by Mr. Ji. X. 
Jack were obtained need not he repeated— it will be found by referring to the Eeport 
on ‘ Geological Observations in the North of Queensland’ already quoted.
