west of the quartzite ridges, and the consequent impossibility of 
tracing out the different outcrops of slates, limestones or traps conti- 
nuously for any long distance. The direction of these stepped faults 
appears to have been generally north-west to south-east, with a down- 
throw to the south of about 470 feet vertically in the southernmost 
break. This throw decreases in the succeeding northerly steps. 
To some extent, this series of parallel dislocations accounts for

bend must have been mainly given long prior to the period of dislo- 
cation now referred to. Indeed, the original floor of the formation very 
probably had something of this form; which was subsequently much 
exaggerated by the squeezing up which the whole kapapan formation 
received from the eastward.

ably the red sandy, slaty shales with limestones 
of the Vaimpullys. The lower beds are very coarse thinnish-bedded 
brown grits and pebble beds, which again overlie an exceedingly coarse 
conglomerate of fragments of quartzite of many colors, brown slate, 
and some jaspers. Occasionally it is a very ferruginous conglomerate. 
The whole slope of this higher part of the hill consists of three beds 
which again overlie grits. The two form the scarp of a steep western 
slope leading down to the valley below, and in this on the opposite side 
are unmistakeable limestone beds of the Vaimpullys forming a round 
little hill with contoured outcrops exactly like other hills in the northern 
part of the Vaimpully belt. But between the quartzites of the top of 
the hill and the limestones, there are some red and white streaked 
coarse caleedonic and jaspery beds, with quartz and eale-spar strings, 
which are rather broken up and knocked about, and, as it was eventually
