of 3 maunds per acre of superphosphate should be made to the cake 

 application. We should thus have : 



1st year Oilcake and superphosphate applied as above in March, Mati Kalai sown 



in August, hoed in at the commencement of October. 

 2nd year Nothing. 



3rd year Green manure in spring with mati kalai, 

 4th year Oilcake applied as above, in March. 

 5th year Green manure in spring, say with mustard. 

 6th year Nothing. 

 7th year Oil cake and superphosphate. 



To the application of oilcake in the tenth year 5 cwt. per 

 acre of wood ashes should be added, and, if the land shows sign 

 of becoming sick of mati kalai so that less vigorous growth 

 is obtained, mustard should be substituted for it occasionally, 



DIBRUGARH DISTRICT, 



East of the Subansiri on the north bank of the Brahmaputra 

 there now exist practically no tea gardens. The whole country 

 is low and more or less under the dominion of the waters. 

 Almost immediately on crossing the Brahmaputra and its tributary, 

 the Dibru, higher land is reached, and the land between this 

 and the Dehing consists of a series of ridges, which form 

 perhaps the best land in India for the growth of a large quantity 

 of high class tea. On one of these ridges runs the Rangagora 

 Road with its group of gardens. On another lies the railway, 

 and near it another group, while still another lot of gardens are 

 placed near the road to Jaipur. The whole configuration of the 

 land in ridges, in many cases of different types of soil, of different 

 vegetation, renders it impossible in this district to lay down distinct 

 and definite rules for treatment and manuring as I have done on the 

 north bank of the Brahmaputra, and I must restrict myself to those 

 cases which I have personally examined. 



Soon after leaving Dibrugarh on the Rangagora road, there is 

 found in places the remains of an ancient forest buried beneath 

 alluvial deposits between the road and the Dibru river. This was 

 noticed at Mothola, and the material obtained is excellent as a 

 top-dressing manurial application. It is worth while to put this note 

 on record, as if such deposits occur extensively, they will become 

 valuable to the gardens on which they are found. Further along 

 the road the land apparently becomes more and more sandy, with a 

 sudden descent into the bheel land near the Dibru. Such land as 

 this, so far as can be seen without analysis, is deficient in organic
