over the surface from east to west, and within that space the 

 quartzite beds are found dipping in both directions. Western 

 Bide dip not ascertained, eastern side dip 35° east, strike 10° 

 east. A few chains north of this point, and about six chains 

 east from the outcrop of the band, seemingly a reef of quartz 

 of milk whiteness steals in amongst the clay-slate, running 

 parallel for a little distance with the strike of the quartzites. 

 At a distance of about one quarter mile we reach the spring 

 (Spring Gully) ; here the band is split into three sections. 

 Thickness of the western section, about 80 feet ; dip, 77° 

 easterly ; strike, 10° west ; overlying clay-slate, about 40 feet ; 

 dip, 75° east ; strike, 8° west ; quartzite, about 40 feet ; dip, 

 75 east ; strike, 8° west ; clay-slate, about 80 , feet ; to the 

 east of which is exposed the largest section of quartzite, repre- 

 senting, from west to east, a surface measurement of four 

 chains, the western side of which is dipping west at an inclina- 

 tion of 65° west, strike on that side of the fold 10° west. On 

 the eastern side of this partially abraded fold the actual dip 

 of the quartzites was not ascertained. Two chains east from 

 their junction with the clay- slate the dip of the latter was 

 found to be 70° east, strike 8 east. 



On the north slope of the gully the phenomenon presented 

 at the spring becomes altogether obscured, but in a gully 

 obliquely intersecting northern boundary of Section 2183 the 

 band is again exposed in a connected form, though still exhibit- 

 ing a somewhat irregular and confused appearance ; dip of 

 slate rock on western side 70° east, strike 10° west. It then 

 passes on through Sections 3323, 3324, and 3329, where it 

 becomes entirely covered with slate rock, in which state I 

 believe it passes through Section 3333 — marked spring — for in 

 the bed of a small gully near the southern boundary of Section 

 3336 the round back of an anticlinal roll is seen peeping out 

 under the overlying clay slate. Prom this point, both the 

 western and middle bands — (nothing of particular interest is 

 connected with the middle band north of cross section) — seem 

 to split up into detached and unreadable sections, as they 

 pass through Section 3335; and in Section 3343, it becomes 

 almost impossible to define the position of their outcrop, and 

 so continue in that obscure state until reaching the south bank 

 and bed of the River Para in Section 3346. 



Eastern Escarpment Series. — By the map it will be seen that 

 a distinct series of quartzite bands traverses the eastern side 

 of the uplands of the district. Their general bearing is con- 

 siderably more west of north than those traversing the western 

 escarpment of the Munno Para Hills. I have thought fit to 

 term the series as above, because, whilst the features of the 

 country were being sculptured by the successive action o£
