tion of this firm to put in a pump, as a much greater quan- 
tity will be required to supply their own and their tenants’ 
requirements. 
The White well has a total depth of 266 feet, 60 feet 
through clay and gravel and 206 feet through rock. Water 
was obtained at a depth of 258 feet, but drilling was pushed 
to a further depth of 8 feet. 
The Laing well has a total depth of 325 feet; 56 feet 
through clay and earthy material and 269 feet through 
rock. Unfortunately none of the rock matter removed in 
boring these wells has been preserved, except a single 
fragment from the White well to which reference will be 
made again. 
A partial analysis of the water from each of these wells 
has been made and the results in grains per imperial gallon 
are as follows:

When the sample of Laing water was sent for analysis, 
the Messrs. Laing wrote saying that although it was turbid 
it was as clear as any they could obtain, nothwithstanding 
that they had been pumping for weeks. A few days after 
the analysis of the sample had been made the turbidity 
disappeared, and Mr. Laing informs me that ‘‘the pump 
is now delivering water that shows no cloudy matter what- 
ever,’ and has sent me a sample which confirms his state- 
ment. 
It is worthy of note that these two waters, which 
represent wells a short distance a part should show 
such a difference in their contained solids. The salts 
in the Laing water are such as one with a knowledge
