is necessary to make it so, and in No. Ill no amount of cultivation 

 gives real luxuriance to the bushes, these figures form a strong argu- 

 ment in favour of a light fairly coarse sandy soil being the condition 

 preferred by the tea plant. 



I will quote another example. The figures which follow refer 

 to two adjacent gardens in the Dibrugarh District, both good ones 

 and giving good tea, but the first of which is and has always been 

 more luxuriant than the second. Chemically the analyses are 

 almost identical, but the size of the particles is quite different, 



Thus we have again 



While it would have been impossible to explain the difference 

 between the two gardens on chemical grounds, yet this determination 

 of the size of the particles in the two cases at once made clear the 

 cause of the difference in luxuriance. 



USE OF SAND TO RENDER SOIL FRIABLE, 



Among other means suggested for bringing about this looseness 

 of the surface soil, the addition of sand has been indicated to me by 

 more than one planter, and no donbt the beneficial effect of much 

 of the top-dressing done on stiff soils in recent years has been, not 

 the result of the intrinsic richness of the material applied, but rather
