river between the " Walsh " Station and Palmerville. Warner 

 made the latitude 16 16" 59" S., but according to the 4-mile map 

 it is about 16 22'. 



On ijth July, Hann, Taylor and Tate rode 13 miles SE. 

 up the left bank of the Mitchell and CAMPED. The first 8 miles 

 were on basalt country, in which agates were found. The next 

 2 miles were on limestone and the remaining 3 miles on slate. 



To the right of the route the hills rose into a sandstone-capped 

 tableland which Hann named TAYLOR'S CARBONIFEROUS RANGE. 

 Taylor had already found Glossopteris and other fragmentary plant 

 remains in a portion of the range about a mile south of Camp 16. 

 Some years later he kindly wrote for my use some " Notes on the 

 Geology of Hann's Exploring Expedition." ' At that time I regarded 

 the whole of the fragmentary sandstone tablelands as belonging 

 to Daintree's " Desert Sandstone " formation (Upper Cretaceous). 

 Subsequent observation made it evident that, whatever their age, 

 TAYLOR'S RANGE AND MOUNT MULLIGAN, on the Hodgkinson, were 

 once continuous and were now only separated by the accident of 

 denudation. The MOUNT MULLIGAN TABLELAND extends for 

 1 6 miles from near Woodville, to the confluence of the Hodg- 

 kinson with the Mitchell, a distance of 24 miles. Taylor traced 

 the TAYLOR'S RANGE for about 12 miles ESE. from Camp 16. 

 The distance intervening between where he left off and Mount 

 Mulligan is only 40 miles, and although I do not know the locality 

 well, I have little doubt that the hill-shading on the 4-mile map 

 passing south of the O.K. COPPER MINE correctly indicates the 

 continuity (with gaps, perhaps) of the two ranges. A seam of 

 COAL is now known to underlie the whole of the Mount Mulligan 

 tableland, and a RAILWAY LINE from Dimbula now connects the 

 coal with the copper region. Mr. Lionel Ball, of the Geological 

 Survey, has established the PERMO-CARBONIFEROUS AGE of the 

 Mount Mulligan beds, 8 and to that age Taylor's Range must also 

 be referred. 



On 28th July, an arduous march of 15 miles was made to 

 the east up the valley of the Mitchell over " horrible slate 

 country," the slates, " sharp as knives," proving very severe on 

 the horses. The CAMP for the night was pitched east of the 

 pinnacled hills south of GROGANVILLE (ANGLO-SAXON GOLD MINE) 

 and north of the O.K. COPPER MINE. These hills, named 

 " WARNER'S PEAKS " by Hann, now appear on the maps as " THE 

 PINNACLES." 



The following day (2gth July), an unsuccessful attempt was 

 made to get better travelling on a south-east course away from 

 the river, but the " knife- edged slates " drove the party back to
