S.S.E of the niaiii sliaft a hole was put dnwu at l{ on map to a 

 depth of 104 feet. I>y two miners named Murphy and Husst. while 

 still further S.S.K. at S. on the map. another shaft, sunk i)y 

 other iniwers, named Jeidvins and Bielski, penetrates the deposit 

 for 55 feet, and by l)orin<j: a fui-ther K) feet a deptli of 65 feet was 

 reached. 



AH these shafts and hores eontinued in the deposit t(j the lowest 

 depths reached, when sinking was abandoned. 



The relations of the deposit to the Ordovician rocks is peculiar. 

 Tlie shallow section in the E. and W. Lrully, cuttin},^ the deposit 

 shows an almost vertical contact between the two formations. 

 Further evidence of a sinular kind occurs near the bore at R on 

 the map. Eighteen yards S.W. of i\ie bore Ordovician slates and 

 sandstones outcrop on the west side of the gully. Tliey strike north 

 12 deg. west, and dip exactly at 80 deg. Since the bore penetrated 

 the deposit for 104 feet, without reaching the Ordovician, it follows 

 tliat the angle of contact between the deposit and the Ordovician 

 must exceed 60 deg. The average strike of the Ordovician rocks 

 near the deposit is north 10 deg. -20 deg. west. On the west side 

 of the gully the rocks dip west at high angles, and on the east side 

 they dip east at from 50 deg. -70 deg., as shown on map. An 

 anticlinal fold or line of centre country therefore runs almost 

 parallel with Kangaroo Gully, and the north-west part of the 

 outcrop of the deposit crosses the axial line. This line is evidently 

 the s(uitherly continuation of the Bird's line of reef. The shaft of 

 the Bird's mine lies 15 deg. west of true north from the deposit in 

 Kangaroo (iully. Along this axial line a monchi([uite dyke cuts tlie 

 dei>osit as shown on the map at the north-west part of the outcrop. 

 The dyke is about 1 foot wide, and has been traced on the surface 

 for about '{O yards. The strike of the dyke is north 14 deg. west, 

 and the dijj is nearly vertical. l)ut really at a high angle to the- 

 east. It is to be noted tliat the area occupied by Ordovician rocks- 

 on the map is left unshaded. 



Some patches of r])per Tertiary sands, clays, and ironstones 

 occur to the south-west of the deposit, as shown on the map, and 

 are also indicated at the points A and B on the map. A is a small 

 patch exposed in a dam; B is ii'onstoiK' from a small dam. while 

 (' lepresents a shaft sunk -lit feet in Ordovician sandstone.
