Volcanic Necks at Anderson's Inlet. 165 



The most westerly one is a narrow dyke 1 foot wide and 15 

 feet long, bearing 312 deg. The I'ock is a dark blue rock of 

 medium texture. 



The middle, and much the largest, one has the shape of a 

 lenticle truncated at both ends. It has a bearing of north and 

 south, with a length of about 15 yards, and breadth at north end 

 of 4 yards, and at south end of 4 feet. It is composed of a 

 highly spheroidal, slightly vesicular, rock. This is highly de- 

 composed, and differs in character from the basalt of the necks. 

 It appears to be more of a mud basalt, and peels off into thin 

 shells. 



The last local occurrence of basalt to record is what appears to 

 be a dyke branching from Neck 4, either from the dyke on its 

 eastern margin, or from some larger body of basalt in the fiat, 

 hidden from view by sand. Small blocks of it can be seen at the 

 foot of the cliff on the eastern boundary of allotment 3, parish of 

 Drumdlemara, within which allotment are also embraced Necks 

 3 and 4, and portion of Neck 2. This dyke can be traced for at 

 least '2h chains west from the boundary, and also for some 

 distance to the east. It has a general bearing nearly east and 

 west. 



Adjacent District Volcanic Occurrences. 



Before leaving the consideration of the necks, it is advisable to 

 mention several occurrences of laterite, basalt and tuffs that occur 

 in the plains to the north and west of the Inlet area. Five of 

 these, occurring in allotments 9, parish of Kirrak (M. Ruttle) ; 

 31, Kirrak (W. Watson) ; 30a, parish of Kongwak (A. Blew) ; 

 37, Kongwak (J. McDowell) ; 38, Kongwak (R. W. McDowell) 

 consist of laterite and tuffs with lapilli. Three others, occurring 

 in allotments 23c, Kongwak (E. O'Connell) ; 41a, Kongwak 

 (Beard) ; 97, parish of Leongatha (L. Follgrabe) and 25, Leon- 

 gatha (D. Millar), consist of laterite, tuffs with lapilli, and basalt. 

 One of basalt only, but occupying an area of only a few square 

 yards, occurs in allotment 55a, Drumdlemara (M. Crowley). 

 There are several other places on the plains nearer Leongatha, 

 where volcanic rocks occur, but these I have not examined, .so 

 cannot discuss them. One notable example, however, near Cape 

 Paterson, exposed on the beach at low tide, may be mentioned.
