;. THORN-FOREST CLLMATIC IN CIS-GANGETIC INDIA. 



The peniii.sula of Hindustan affords the amount of rainfall necessary 



r liigh-forest (rain-forest and monsoon-forest) only on its west coast, 

 lid a small part of its north-east territory in the monsoon district of 

 iie Ganges and Brahmaputra. In the central parts of the peninsula 

 he rainfall is mostly 760-1,900 mm., and according to Hann's map 

 here is an extensive district lying between 80° and 88° E., the tropic of 

 ancer, and 18° N., in which the rainfall is about 125 cm. The southern 

 nd north-western parts of the peninsula are, on the whole, much drier 

 :5Ho-76o mm.) ; the north-western part borders on the western district 

 India. 



All these districts experience summer and winter rain, except the 

 outh-eastern (Madras), where autumnal rain prevails. They are covered 

 .'ith thorn-forest and semi-desert, according to the rainfall. Tree-growth 

 5 nowhere entirely excluded (Fig. 126). 



The climate is ever\-where suitable for woodland, never for grassland : 

 luring the vegetative season it is extremely hot, usually very dry, the 

 itter especially during the cool winter and spring months.
