Pleistocene Period. 



Raised Beaches. — At the mouth of the E-iver Thames, near 

 Auckland, there is a raised heach some 10 or 12 feet in height 

 containing marine shells *, and at the IS'orth Head of Manukau 

 Harbour a well- cut beach- terrace is seen at about the same 

 altitude f. 



Below the town of Tauranga there is a raised beach about 

 2b feet above the sea. Beach-terraces are plainly seen at ffick's 

 Bay near the East Cape ; but I have never landed to examine 

 them. At Taranaki Dr. Hector has described Pleistocene deposits 

 with recent marine shells at 150 feet above the seat. Beach- 

 terraces occur also near Wellington ; and Mr. M'^Kay describes them 

 as much more than 200 feet high near Cape Palliser, in Cook's 

 Straits §. On the west coast of the South Island Dr. Hector 

 mentions comparatively recent beach-terraces extending to more 

 than 220 feet above the sea ||, and Mr. Dobson has estimated these 

 terraces at 400 feet %. At Amuri Bluff there are three terraces, 

 and Mr. M^Kay obtained recent marine shells from the highest, 

 which, he says, is 500 feet above the sea**. These three terraces 

 are also seen a httle further south, at the mouth of the river Conway. 

 At Motannau, in 1^. Canterbury, a raised beach with marine shells 

 goes to a height of 150 feet above the sea. A deposit of fine silt 

 occurs along the east coast of Canterbury and Otago from Banks's 

 Peninsula to Moeraki. At its base it is stratified, frequently with 

 layers of gravel, but its upper portions are unstratified. At Timaru 

 it contains a few marine shells ft. At Oamaru the gravels at its base 

 contain large numbers of recent marine shells %%, and the upper 

 parts have yielded Moa-bones, and the skull of a large Sea-Elephant 

 {Morunga elejpTiantina). This silt goes to a height of 800 feet in 

 Banks's Peninsula §§, and to 500 or 600 feet at Oamaru||[|. Also the 

 entrance to the West-coast Sounds are terraced to an estimated height 

 of 800 feet. 



If we plot these heights and distances to scale it appears

II II The marine origin of this deposit is, however, disputed! Dr. von Haast 

 considers it to be land loss. See Geol. Canterbury, p. 367, and Trans. N. Z.
