From the table-land, upon which, on the North-shore of Lake 
Taupo the picturesque Tauhara volcano arises, there extends in a 
northeasterly direction with a gentle slope towards the Bay of Plenty 
the Kaingaroa 1 plain, an extensive plain, fifteen miles wide and 
channelled by numerous valleys. Vast quantities of pumicestone 
cover the almost tree-less plain, the scanty soil of which pro- 
duces only a meagre growth of grass and low shrubs. It appears, 
as though in olden times a powerful stream had taken its course 
over the plain to the sea. On the East-side the plain is bordered 
by the Te Waiti range striking in the direction of the East Cape; 
on the West-side by a volcanic table-land cut up and broken by 
faults and dislocations into a thousand hills and mountains, which 
1 Kui-ngaroa signifies a protracted meal. The name refers to the legend about 
a female relative of the chief Ngatiroirangi, who arranged here a protracted meal, 
and changed her companions into ti-trees, which are still standing there, but are 
said to be continually receding at the approach of the traveller.
