Note^ on General Hand^s Letter. 



I am sorry that one so capable, as well from professional 

 knowledge on chemical subjects, as opportunities of acquiring 

 and making agricultural observations, has avoided comments 

 and matters of opinion. Having hazarded these myself, I 

 should the more gratefully have received them from those 

 more capable of forming just opinions and well founded con- 

 jectures.
