24 Notes on some Evidences of 



schists and intrusive dykes which make up the formation 

 of the Livingstone Creek Yalley. Following the creek 

 downwards from the upper moorland flats, which vary in 

 width from 40 to 100 chains, the valley narrows by the 

 near approach of high lateral spurs of contorted mica schist, 

 which in some cases is seen to be intruded upon by masses 

 of quartz-mica diorite. About seven miles from its source, 

 the Livingstone receives a tributary from the east (New 

 Rush Creek), on which are situated some gold workings in 

 heavy auriferous gravels and bouldery wash ; many of the 

 boulders are striated and exhibit flat surfaces. On the 

 margin of the raised flats, at the junction of the two streams, 

 are masses of angular detritus in a stiff clay, together with 

 large waterworn boulders and blocks of the quartz-mica 

 diorite of the higher levels, and also some rounded boulders 

 of quartz conglomerate similar to those in the Went worth 

 Valley, and which, so far as known, do not occur in sitio in 

 the Livingstone Creek watershed, but which are distributed 

 along the latter to lower levels, and are to all appearance 

 erratics. Some large flattened quartz boulders are also seen 

 similar to the mass which outcrops on the main Divide some 

 twelve miles distant (to the east), viz., at the New Rush 

 Creek. From this point the ranges forming the eastern 

 watershed of the Livingstone are more undulating and 

 lightly timbered, while on the west, high, bold, wooded 

 ranges rise rather abruptly in steep spurs from the creek 

 flats to an elevation of 4000 feet. Near Mount Living- 

 stone — a bold, rounded peak south-west from Omeo — 

 the Livingstone Creek receives an important affluent 

 from the west. This affluent — Jim-and-Jack Creek — 

 although it traverses a rock-bound gorge, where it flanks 

 Mount Livingstone, yet opens out into some richly 

 grassed upland flats and rolling pasture hills, with out- 

 crops of grey, crystalline rocks (gneiss) on the points of 

 the undulating spurs, which show faint traces of striation 

 in the direction of the valley. A low gap separates this 

 area from Parslow's Plains, previously described. At various 

 points in the rocky gorge of the lower part of this stream 

 are rounded hillocks, generally at the termination of spurs 

 at an angle or trend of the valley. They are seen to consist 

 of masses of waterworn boulders in a stiff, tenacious clay, 

 capped generally with gravels of later date. From the 

 junction of Jim-and-Jack with the Livingstone Creek, 

 the latter has eroded its present channel through recurring
