Conclusions. — In this experiment we observe — 
1 . Tliat^ upon a soil which has had rape-dust as a manure for 
a length of time, a dressing of saline manures may be advantage- 
ously used upon the barley crop. 
2. That, as upon oats, so upon barley, common salt has a ten- 
dency to increase the quantity of grain in a greater ratio than the 
straw, to improve the quality of the grain, and to render the straw 
white and brittle, and to promote its ripening. 
3. That the nitrates have a tendency to increase the quantity of 
straw in a greater ratio than the grain, to render the straw soft 
and bulky, and to retard slightly the ripening. 
4. That the nitrates have not such a decided effect upon the 
colour of the young plant of barley as upon oats or wheat. 
5. That the action of salt upon the crop is not visible so soon as 
that of the nitrates. 
6. Tliat rape-dust has a tendency in this case to diminish the 
weight of the grain per bushel. 
7. That nitrate of potash also diminishes the weight per bushel 
of the grain. 
K. — Experiment on the actual and comparative effects upon the 
Barley crop, of Rape-dust, Guano, Rape-dust and Salt, Nitrate 
of Soda, and Nitrate and Sulphate of Soda. 
Details. — Good limestone soil, worth 24s. per acre per annum ; 
e.vj)osed to the north ; low fences ; no trees. Prior crops — barley 
(upon turnips eaten on the land) ; seeds (pastured) ; icheat (rape 
dust) ; turnips (bones, crop j)ulled off).
