life, have occasion to make use of the microscope, there exists 
no finer training ground than a study of the structure of 
plants. For the pharmaceutical chemist in that new 
departure which it is their early hope to make, a thorough 
grounding in botanical science will be a matter of necessity. 
But above and beyond all these practical and economic 
applications, there stands the grand educational principle 
that for those who follow knowledge, not as a means whereby 
to earn thirteen pence in the time in which a shilling had 
been earned before, but as a means for the full development 
of those faculties wherewith God has endowed them, there is 
no line of study which is profitless, no line of thought which 
is thrown away. The golden rule of our educational method 
of the future will, I believe, be not to accumulate information 
but to cultivate ability; not to cram the brain, but to train 
and develop the faculties. Knowledge may indeed be power, 
but intellectual power is more than knowledge.

V.—What would be the Expense ? 
The matter of expense is not one that I can deal with 
from personal experience, but it will, nevertheless, be easy to 
show that the scheme that has been described would be 
much less expensive than the one recently adopted by the 
Northampton Town Council. 
The particular advantages, in the matter of expense, are 
detailed below:— 
1. —There would be no reservoir to construct , for the porous 
beds of the Marlstone would hold sufficient water for many 
years of drought. 
2. —There would be no pipes to lay. A considerable item in 
most schemes of water supply is the purchase, and laying of 
pipes for the conveyance of water from the place where it is 
collected to where it is required ;* but here the bed itself 
forms a sufficient means of communication from place to 
place. 
* In the case of Northampton this is about seven miles.
