A comparison of the precetling tabulated results suggests the 
following obserA ations : — 
1. Nitrate of soda, as in previous years, produced a consider- 
able increase both in com and in straw. 
2. The larger application of nitrate of soda produced a corre- 
spondingly larger increase in corn. 
It will be seen that whilst 1 cwt. of nitrate of soda and 2 cwt. 
of salt gave an increase of i'J bushels of com, cwt. of nitrate 
and 3 cwt, of salt gave an increase of 12h bushels of corn, and 
2 cwt. of nitrate and 4 cwt. of salt an increase of 15| bushels. 
Thus for each -i cwt. more nitrate of soda an additional increase 
of almost exactly 3 bushels of wheat was obtained.
