ably also at Waratah Bay, C. Liptrap, and possibly on the 

 Howqua River. He explained the di'^tribution of the Ordovician 

 and Silurian rocks of Victoria in relation to an old Heathcotian 

 land surface stretching across Victoria, and in conclusion sug- 

 gested a subdivision of the Silurian rocks of Victoria into an 

 upper, or Yeringian, and a lower, or Melbournian, series. 



The following papers do not deal with the Heathcote district, 

 but the authors correlate or contrast some of the rocks described 

 with the typical " Heathcote " series. 



12. Stirling, James. "Report on Examination of Reefs at 

 Howqua Valley.'' 'Quarterly Rep. Min. Registrar, Victoria, June 

 30th, 1888, p. 70. In this brief report Mr. Stirling states that 

 Malcolm's reef is situated at Malcolm's C!reek, about one mile 

 above its junction with Lick-hole Creek. It occurs in a dense blue 

 crystalline rock, like certain massive diorites. 



13. Stirling, James. " Pre'liminary report on the Geology of 

 Dookie District," with map and two sketch sections, ibid. pp. 76- 

 77. Mr. Stirling described the structure as follows: — "The 

 rooks ai'e mainly U. Silurian sediments, intruded upon by certain 

 diorites, gabbros, etc. ; the latter have in most cases effected 

 induration or hardening of the former along the contacts, and in 

 some places have caused segregations of iron ore, chiefly car- 

 bonates and oxides. . . . Near Dookie College, ascending 

 the S.W. slopes of Mount Major, the sediments are indurated, 

 the sandstones become flinty and converted into hornfels. . . . 

 Towards the summit of the hill outcrops of hard silicious rocks 

 are seen to be commingled with irregular bands of ironstone." 



14. Ferguson, W.H. " Report on Sketch Survey of Eastern Por- 

 tion of County of Moii'a." Monthly Prog. Rep. Geol. Surv. Vic- 

 toria, No. 10, Jan., 1900, p. 10. The altered rocks of Dookie are 

 regarded by Mr. Ferguson as quite distinct from the Silurian 

 rocks or their metamorphosed representatives. They consist of 

 cherts, quartzites, talcose schists, and ironstone and quartz rocks. 

 Diorites and other eruptive rocks cover largei areas. The dis- 

 trict is traversed by a great numbea- of dykes. 



15. E. J. Dunn. The Settlers' Guide, Victoria, 1905, p. 60. 

 To a pre-Ordovician (Heathcotian) age Mi\ Dunn refers the rocks 

 of Heathcote and Mansfield, and says minor outcropsi occur in 

 several other areas. Bhick slates on the Divide west of the
