On the Hedge Plants of India, and the conditions which adapt them for 
special purposes and particular localities. By Dr. H. CLecuorn, Madras 
Establishment. 
The author first made some remarks on the low condition of agriculture generally 
throughout India, and stated that his remarks more particularly applied to the south 
of that continent, in the district of Mysore, which he had frequently traversed in the 
execution of duty. Having referred to the importance of hedges in any well-deve- 
loped system of agriculture, he pointed out their especial importance in a country 
infested with wild animals, and where the crops needed especial protection. He 
stated, however, that those plants alone could be used for hedges which were adapted 
to the particular soil and climate where they were employed. Sandy districts pro- 
duced a very different vegetation from that which is found in a rich alluvial soil. 
The following plants were named as those which might be used with advantage for 
hedges in various parts of India. Most of these plants are characterized by possess~ 
ing spines, prickles and thorns, which render them dangerous to animals.

The Cacti, Agavee and Euphorbie are adapted to the arid districts, their struc- 
ture enabling them to exist, when refreshed with only occasional showers ; the Mi- 
mosee and Cesalpinee seem to enjoy the somewhat more cold and moist climate of 
the Balaghaut districts; while the Bambusee and Pandanee luxuriate in the rich 
loamy soil of the Mulnad (i. e. Rain country). Hence, for the railways now making 
in the Peninsula, the fences ought to differ as the line is continued through various 
districts, in accordance with the conditions under which particular plants thrive best 
between certain limits of temperature and moisture.

of them are covered with a very perceptible distinct layer of cells which Schleiden
