themselves, who acted as guides; they would climb with me to 
the tops of mountains , whence I made my observations ; they were 
ever ready to tell me the names of mountains, rivers, valleys and 
lakes, and in their own way instructed me in the geography of 
their country. I noted down carefully all the native names, and 
believe that I have rescued many a melodious and significant Maori- 
name from oblivion. 1 The peculiarities of the ground I always 
sketched on the spot; and thus procured a supply of reliable material, 
from which on my return to Auckland I compiled a topographical 
map on a large scale of the southern portions of the province; in 
fond anticipation of ampler leisure-time at some future period, when 
I should be enabled to subject the provisional sketch to a careful 
revision, and to draw from it some detailed maps of special districts. 2 
The observations of the 1 loyal Engineer’s Observatory in Auck- 
land, synoptical tables of which my friend, Colonel Mould, had the 
kindness to furnish me, served as corresponding observations for 
the barometrical measurements made during* the journey. I must 
also make mention of numerous drawings and photographs executed 
by the members of the expedition; likewise of valuable sketches of 
landscape scenery from the talented pencil of Mr. Ileaphy . 3

2 One copy of my original map, on a scale of 2 miles = 1 inch, I left 
in Auckland for the use of the Government; Mr. J. Arrowsmith in London recei- 
ved a second copy, to aid him in the compilation of a large map of New Zealand 
in six sheets, which he had then in view; with the special intimation, however, 
that, the map being merely a copy of that left in Auckland, it should be considered 
merely as a temporary, rough sketch of 1113- observations. To my much esteemed 
friend, Dr. A. Petermann in Gotha, I am indebted for the overhauling and revising 
of all my original sketches and surveys, and the map on a reduced scale, such as 
is found annexed to this work, is the final result of my observations. It is self evident, 
that a map, compiled within the short space of three months, with only the help 
of compasses, and comprising more than one fourth of the North Island, can make 
no pretensions to trigonometrical precision. However, it gives a correct view of the 
river and mountain systems of the country travelled through, and will be of service 
till something better shall have been substituted. A geological and topographical Atlas 
of New Zealand, lately published at the geographical institute of Justus Perthes in 
Gotha, contains all the rest of my surveys and sketches.

this work.
