As little information is on record respecting the composition of 
the various inland waters of New South Wales, and questions 
having arisen at times regarding their value for irrigation, water- 
ing stock, and other purposes, I have much pleasure in, bringing 
before the Society with the permission of the Hon. the Minister 
for Mines and Agriculture, the following information obtained 
after some years of careful work, and examinations made of various 
samples of water submitted to the Department of Mines for 
analyses and report. 
In some cases, the waters were examined with a view of ascer- 
taining whether they were suitable for drinking purposes, and the 
larger portion for stock and irrigation purposes. The analyses 
were conduced according to the information required, a few of 
the samples sent being insufficient for a thorough examination, 
though in most cases the results obtained were sufficient for all 
ordinary purposes. The bulk of the analyses were conducted on 
from one to twelve gallons, especially in waters obtained from 
artesian bores and mineral springs, a large quantity of the water 
being taken for the estimation of the various salts present in 
small quantities. 
The analyses of artesian and well waters furnished in this 
paper, must not be taken as representing the average waters 
usually obtained by boring or well sinking, as in nearly every case
