Volcanic Necks at Anderson's Inlet. 163 



The visible portion has a length of about 3^ chains, with a 

 breadth of about 1| chains, the whole of it as seen being in the 

 cliff and slope of the hill. It has a general south-easterly bearing, 

 and probably extends for some distance out into the flat, but as 

 the flat is here covered with drift and blown sand, nothinsc 

 beneath is visible. Even in the clitf" the nature of the material 

 constituting the neck cannot be clearly determined. 



As fai- as can be seen the neck consists of a plug of dense, 

 hard, dark blue basalt, forming a low swelling on the top of the 

 cliff, and extending in a south-easterly direction down to the 

 flat. As it approaches the flat it narrows very much, and 

 appears to be only a few feet wide at the foot. This basalt 

 apparently forms the eastern margin of the neck. On the 

 western side of the neck there is a considerable quantity of tuff", 

 containing a few pebbles similar to those in Neck 2. Those 

 obtained vary from the size of a small marble to that of a pigeon's 

 egg. There are, also, visible on the surface, pieces of agglomerate 

 and fine and medium-grained decomposed basalt, similar to that 

 in Necks 1 and 2. There are, besides, pieces of what looks like 

 volcanic mud — an amorphous or crypto-crystalline, soft, compact 

 material of dark grey colour. It resembles, somewhat, the 

 small lenticles referred to in one of the basalts of Neck 2, and 

 also that obtained from another volcanic occurrence, probably a 

 neck, situated in allotment 97, parish of Leongatha, to the 

 north-east. 



Volcanic Neck, 4. 



Separated from Neck 3 by Jurassic strata, and distant from it 

 5 chains to the east lies Neck 4. Its western margin is clearly 

 defined by a small gully, but on the eastern side there is nothing 

 definite to aid one in fixing its margin. The visible portion of 

 this neck also occurs in the cliff, but probably extends in a 

 southerly direction into the flat, where, however, sand obscures 

 the view. As far as can be seen, it is oval in shape, its length 

 in an east and west direction being about G chains, and breadth 

 2 chains. 



It, again, differs from the preceding necks, inasmuch as it is 

 almost wholly composed of a homogeneous grey tuff containing 

 grains of sand and a few pebbles similar to those in Necks 2 and
