PART I.-SOILS. 



Chapter I. Geological Strata. How they can be all studied on the 

 surface, in definite order; unstratified rocks, igneous ; metamorphic and strati- 

 fied rocks ; the Lower Magma, formation of trap-rocks and regur ; the Upper 

 Magma, granitic soils; sub-metamorphic and Vindhyan systems; gneiss, 

 schists, slate, quartzite, and crystalline limestone; Gondwana system, Encri-' 

 nitic limestones, sand stones and coal-measures including iron and limestone 

 rocks; Triassic, Liassic, Jurassic and Oolitic rocks; Eocene (nummulitic lime- 

 stones), Miocene and Pliocene deposits, fossil remains of mammals in Siwalic 

 Hills; Pleistocene deposits; Laterite; Alluvial deposits; summary of the geolo- 

 gical strata of India. pp. 14 to 25. 



Chapter II. Surface-geology of the Bengal districts. The Old and 

 New Alluvial tracts ; Laterite region and laterite patches ; glacial boulders ; the 

 two Cuddalore bands; Tertiary and Cretaceous regions (in Eastern Bengal, As- 

 sam and Orissa hills) ; Gondwana deposits consisting of (i) Rajmahal trap (from 

 Ranigunge northwards and westwards through Birbhum, Damodar valley to 

 Hazaribagh, also in Cuttack, in the Son valley, and in Palamau), (2) Jurassic 

 beds of Rajmahal, (3) Panchet and Dubrajpur rocks, (4) Barrakar rocks 

 including coal, (5) Talchirs and (6) Damudas (Ranigunj to Chanda); Upper 

 Vindhyans of Chunar; lower Vindhyans in the Son Valley; transition rocks 

 in Manbhum and Singhbhum ; gneiss and granitic intrusions in Chutianagpur 

 Division and Monghyr ; Dome-gneiss; trap dykes rare in Bengal gneiss; 

 Bengal trap (i) Cretaceous (W. of Chutianagpur), (2) Rajmehal and (3) 

 Archaean (Singhbhum). pp. 26 to 33. 



Chapter III. Formation of soils. Sedentary and transported soils ; 

 kankar and gypsum in the latter ; knowledge of composition of soil and stones 

 how far useful ; external characters, evidence of composition and fertility ; Fossil 

 remains indicative of fertility; value of archaean and metamorphic soils ; Trap 

 rocks and volcanic tuffs making superior soils ; presence of felspathic stones 

 desirable; Disintegration by a aqueous, atmospheric, physical and organic
