Conclusions. — It will be here observed that — 
1. Nitrate of soda, nitrate of potash, and soot, have a tendency 
to increase the produce of wheat, both straw and grain. 
2. That common salt has a slight tendency to increase the 
produce of grain, and to decrease the iceight of straw (mark, the 
weight of straw, as it will be observed — vide number of sheaves 
per rood — that it does not diminish the bulk), and that common 
salt increases the weight per bushel of the grain ; thence it may, 
from these properties, be advantageously used as an auxiliary to 
other manures. 
3. That sulphate of soda has no visible effects upon the wheat 
crop. The slight variation in )ield of straw and grain may be 
fairly attributed to accidental circumstances, such as variation 
of soil, tScc, as no two patches can be perfectly equal in every 
respect.
