la all forest conservation, it should be remembered that the substratum plays an 

 important part in the growth of trees, and that much depends upon it. By way of illustration, 

 and for a better understanding of my subsequent remarks, I give the annexed sketch of the 

 different growth of Yindyke* {Dalhergia cultrata) on various substrata.

I entertain gome doubt as regards the difference in growth of yindyke as shewn in figs 1 and 2. 1 suspect that 

 growth 1 is the prochict of alluvimn resting on highly plastic and retentive clay ; while growth 2 may be produced by 

 alluvium resting on fine quartz sand. Unfortunately I have had no opportunity of obtaining a section of the 

 strata in these localities
