surface as those just discussed, but even in character down to four or 

 more feet. It is somewhat more clayey than those of which we have 

 just been speaking but on account of its depth is, usually extremely 

 durable. The following are analyses of this soil in various stages of 

 tea culture. 



I consider that precisely the same systems of manuring suggest- 

 ed for the grassland (Panitola District) will answer on this. Green 

 manuring might, however, occupy even a more prominent place, and 

 the growth of sau trees, and bushes of bogga medeloa will probably 

 be of great advantage. 



To the south of this group of gardens towards the Dehing, the 

 country becomes much lower and more broken up, and tea can only 

 be planted on occasional ridges. These seem to be the oldest 

 places in which tea was known in Assam, and are those from 

 which, to this day, the very highest jdts of tea are derived. The 

 soil is a light loam, dark in colour, and deep in character where free 

 from water, and bears forest, generally of dense character. The 

 Dehing valley, in fact, as a whole where high enough, forms a district 

 which is excellent, in regard to soil, for the growth of tea. Near 

 the upper end of the cultivated portion it becomes gravelly and 

 stony at a very short distance from the surface, but the soil itself 

 is very good. 



DOOM DOOMA DISTRICT. 



If instead of crossing to the Dehing, the course of the Dibru 

 river and its tributaries be followed up, the Doom Dooma district is 

 reached, which consists of alternate ridges of fine and coarse fairly 

 sandy soil, the directicn of which seems at somewhat of an angle
