Tin* following tables (Tables 11 and 12) show, both in percentages 
(parts per million in the case of the nitrogen in nitrates) and as 
pounds per acre, for cadi plat and for every depth of soil examined, 
the total nitrogen, the nitrogen as nitrates, and the organic carbon, 
together with the ratio of carbon to 1 nitrogen and of nitrogen to 100 
carbon. For many purposes it is convenient to have all of these 
expressed side by side. For the consideration and comparison, how- 
ever, of the (plant it ies of each single const it nent , it is more convenient 
to have the nitrogen and carbon results tabulated separately, in such 
a way as to show in one line the quantities present in each successive 
depth of each plat. Tables 1. 'J, 14, 15, and 10 exhibit the total nitro- 
gen and organic carbon contents of the soils and subsoils in this 
separate form :
