Added to this is other evidence on the eastern and southern mar- 

 gins of what may be called the Mansfield Senkungsfeld, which will 

 be dealt with further on. 



(b) — "The Ilillfops^' and Gallows Hill. — The chief product of 

 Tolmie is potatoes, grown in the rich volcanic soil of the hilltops. 

 From one such farm, about 3000 ft. above sea level, the owner 

 stated that it cost £2 7s. 6d. per ton to place his potatoes on the 

 Melbourne njarket, owing to transjiort difficuties. Although Nature 

 has provided Tolmie with patches of excellent soil, she has given 

 a physiography which is severely against progress. The hilltops of 

 older basalt are similar to those occurring in many other places 

 in Vic. (See Fig. 6.) This leads to the anomaly of cultivated hills 

 and heavily-timbered valleys. 



Gallows Hill is the only "hill of accumulation "' known in the 

 district. The accompanying diagram (Fig. G) shows the main 

 features of the southern part of the Tolmie highlands. 



(c) Mount Battery. — This hill (1760 ft.) is an interesting example 

 of the influence of internal structure on external form. The level- 

 bedded rocks give it its flat top and characteristic and numerous 

 ledges and scarp faces. (Fig. 10.) 



((I) Mt. Terr// and Spriiii/field J/ ills. — These are in the lower 

 carboniferous sandstones east from Battery, and present an abso- 

 lutely different appearance. They have a fairly steep dip westerly, 

 and the difference in tlie topography thus brought about is striking.
