the agricultural and horticultural products of European extra- 

 tropical countries may be successfully and profitably culti- 

 vated amid our sub-Alpine elevations ; in fact, the only 

 barrier at present existing is that of transit to a market; 

 a good road to the seaboard, distant about sixty miles, being 

 a desideratum. 



As settlement progressed in these regions, a number of 

 herbaceous plants were introduced ; these, however, I have 

 not included in this list. The principal rock formations 

 within the area under consideration consist of Silurian and 

 altered Silurian — i.e., metamorphic schists, gneiss, &c, includ- 

 ing many varieties of quartz porphyry, granite porphyry, &c, 

 basaltic table-lands, numerous igneous dykes intersecting 

 and intruding upon the metamorphic schists ; also patches of 

 Middle Devonian sandstone and limestone, with deposits of 

 tertiary gravels along the courses of streams — in fact, what my 

 friend, Mr. A. W. Howitt, has described as the "great paleozoic 

 rock foundations of North Gippsland," intruded upon by 

 subsequent Plutonic masses. The following arrangement is 

 that of Baron von Mueller : —
