PREFACE 
N August I St, 1907, I delivered 
a lecture, on the Care of Natural 
Monuments, at the Leicester meeting 
of the British Association for the Ad- 
vancement of Science. The lecture 
was given at a joint meeting of the 
Geographical, Geological, Botanical, 
and Zoological sections. 
The present book may be regarded 
as the above lecture in an extended 
form ; and, in publishing it, I am 
acceding to the expressed wishes of 
my English friends. 
Whilst the book makes no pretence 
to deal exhaustively with the subject, 
I hope that it is sufficiently compre- 
hensive to be acceptable and service- 
able to naturalists, and, indeed, to 
lovers of nature in general.
