GooDALL. — Blasting at Ahuriri Bluff, Najner. 649 



one of tlie names of Kali (a name that is given to the extreme 

 point of Peninsular India, that is, Comorin,) is Kiunaii ; and 

 Kiimari is sufficiently near kuinara to clinch the connection that 

 I sought to trace by inference. 



I have but to add, in bringing this investigation to a close, 

 (that is to say, the Turanian portion of the subject,) that if the 

 conclusions I have advanced are borne out by the facts adduced, 

 any disappointment that the lovers of the Maori, and things 

 Maori, may feel at the identification of the Mahori race with the 

 Mahari, or scavenger caste of India, is amply compensated for 

 by their connection with the illustrious Phoenicians ; to whom the 

 ancients OAved so much, that even the Greeks thought it no 

 reproach to acknowledge and insist on their own obligations to 

 them.

Plate XXVIII. 



The starting-point of the Napier Breakwater being from Ahuriri 

 Bluff, where the sea at high- water washes the base of the cliffs, 

 it was found necessary to make room for the erection of working 

 plant, offices, block yards, and other pui'poses. To enable this 

 to be done, and also to procure rubble stone for the works, it 

 was decided to blow down the face of the cliff, immediately 

 adjacent to the works. This cliff' is over 300 feet in height, 

 and is composed of alternating strata of limestones and sand- 

 stones. At a height of 50 feet from high-water, two drives were 

 put into the hill, each 90 feet in length and quite straight, in 

 different directions. These were turned at right angles, and 

 driven 12 feet further, and turned again at right angles to 

 the original direction and driven 8 feet, making double elbows. 

 The mouths of the drives were 3 feet wide by 5 feet high. They 

 were narrowed at the extremity as much as possible, so that a 

 man could just work. The end of the drives led into chambers 

 prepared for the explosives used. The material worked into 

 was a bed of sandstone, moderately soft at first, but gradually 

 becoming harder and more difficult to work, till at last three men 

 in three shifts (a man to a shift) would extend the drive 2 feet 

 only ; while, at the start, the same complement of men in the 

 same time could do 5 feet. 



The first drive put in was for a charge of blasting-powder, 

 consisting of eight tons (2,0001b. to the ton). The inside dimen.
