of our distinguished President, Sir R, Murchison. I may here 
observe, also, that a fine molar tooth of Hlephas antiquus has 
lately been found, by Henry Brooks, among the gravel which 
overlies the great masses of angular blocks heaped against the 
side of a hill, known as Clincher’s Mill Wood near Ledbury. 
This angular debris I pointed out to Mr Prestwich, who agrees 
with me in attributing its deposition to the effect of coast ice 
drifting, during the glacial period, down one of the ancient 
Malvern bays. 
I have also observed the high-level drift at several points in 
Herefordshire, the principal of which is an excellent section, 
near the Kite’s Nest, on the Hay road, about four miles west 
of Hereford. There are many other subjects and localities, 
to which I would allude, but I have already trespassed upon 
your time, and sufficient has, I trust, been said, to correct the 
error I committed. 
REVIEWS AND NOTICES OF BOOKS. 
The Forests and Gardens of South India. By Huen CiEe-

sidency. London: W.H. Allen & Co., 1861. Pp. 412, 12mo. 
The conservancy and management of forests is a subject of great 
importance, not merely in reference to the supply of useful and 
valuable timber, but also as regards the climate of a country. 
The cultivation of good timber trees, which may be used in the 
construction of houses and ships, and for railway sleepers, demands 
the serious attention of all nations; and in countries where coal 
is wanting or deficient, the acquisition of wood for fuel is one of 
the necessaries of life. In many countries there has been too 
little attention paid to the preservation of trees, and valuable 
timber has been indiscriminately felled, while no steps were 
taken to replace what had been removed, Where new colonies 
have been planted in densely wooded countries, the first work of 
the settlers was necessary to clear land for the cultivation of 
crops; and as the population increased, the trees became less and 
less abundant. In some instances the felling has taken place in 
such a way as materially to injure the climate of the country, by 
diminishing the amount of moisture in the air, and by drying up 
the springs where water was obtained. In India, serious injury 
was done to the native forests from the want of proper regulations. 
Valuable forests of teak, sal, and sandal-wood were nearly exter-
