49 to 54 Dr. Hall refers to the typical Castlemaine series, and 

 51 prububly highest. 51 is about the position at which Krause 

 placed the highest beds. I have no information with regard 

 to these localities, as to their relatiim to one another, and 

 whether they are the higher or lower beds in their iiuniediate 

 vicinity. Between 52 and 54 there is a belt about a mile and a- 

 half in width, from which I have no fossils. I do not think it 

 likely that the trough of a main sjTicline lies at 51, as there is 

 no reappearance yet detected of the Wattle Gully and Bendigo 

 Beds to the East. 



The principal gold workings in quartz are within the central 

 strip or on its margin. This is within the limits which Dr. Hall 

 regarded as gold-bearing at Castlemaine. There is little gold 

 working to the east, w^here higher beds of the Castlemaine series 

 probably occur. Though the western area has not much impor- 

 tant mining at present, it is to some extent gold-bearing, and 

 may correspond to one of the less productive zones which occur 

 even in the Bendigo central area. 



The prevalent southerly pitch at the south end, and prevalent 

 northerly pitch at the north end bring in newer beds across the 

 strike of the Cornish anticline, and cause these beds also to 

 encroach on the area of Bendigo beds further to the west. 



SUMMARY. 



In the above notes I have referred the various beds to hori- 

 zons in accordance with Dr. Hall's subdivision of the series of 

 beds at Castlemaine. In view, however, of the differences in the 

 fossil succession, as described bv him from tliat noticed in other
