CRATER A, AND THE ISLAND N. 
The crater B, next in size to A, stands back about three-fourths of 
a mile from the sea, near the western side of the peninsula. In a dis- 
tant view, this crater has a high conical form, and is obliquely trun- 
cated at top. It is mostly a lava cone; and black rocks form a 
large portion of its northern walls, besides half filling the shallow 
crater. ‘The outer surface is mostly loose soil. ‘The lava of the erup- 
tion flowed off to the northward towards the sea, but is concealed, to a 
great extent, by the coral sandhills that have accumulated on this 
side of the peninsula. The rock is extremely compact and heavy, 
containing but few cellules, and has a black or brownish-black colour, 
resembling that near Diamond Hill. There are some minute particles 
of chrysolite. It breaks with a clinking sound and a smooth con- 
choidal fracture. Externally, the masses exhibit a laminated struc- 
ture; but when broken, the lamination is not apparent. ‘There are 
some loose masses of scoria lying in and around the crater. 
The crater C, is also a lava crater. It is broken down nearly to the 
level of the sea, excepting the eastern and western sides, which stand 
like two rocky hills sixty or eighty feet high. The lava is like that 
just described, and much of it is broken into large blocks, which he in 
confusion together. 
There is also a small rounded elevation at D, half a mile to the 
southeast, which consists of the same basaltic rocks, although there is 
no distinct crater at the present time. ‘They are not connected with 
those of the vents just described, and must have been ejected at the 
spot where they now lie. This is, therefore, a fourth vent. 
The small island of rock (N) standing off Kaneohe Point, must be 
a remnant of a fifth cone: it was not visited. 
This closes the review of the subordinate craters or vents of Eastern
