both. 
2. That salt applied bv drill, along: with rape-dust, produces 
somewhat similar, though not so decided effects, as when applied 
as a top-dressing auxiliarv to rape- dust. Thus we have, in No. 2, 
the highest yield of grain and the loicest of straw, although the 
heaviest weight per bushel of grain. 
Experiments on Wheat. 
M. — Experiment on the actual and comparative effects upon the 
Wheat crop, of Xilrate of Soda, Xitrate of Potash, Sulphate 
of Soda, Soot, and Salt. 
Details. — Soil — moderate limestone, worth 24s. per acre. Prior 
crops — turnips (manured) ; barley (rape-dusted) ; seeds (pastured 
with sheep). 
Management. — Sown with red wheat November 7, and 
top-dressed as follows: — 
Soot.

Observations. — Showers coming after the applications were 
made, Nos. 1 and 2 began to show the effects of the nitrates in a 
few days ; in a fortnight, however, they assumed a rich dark 
green hue, very different from any other portion of the field. 
In the course of a month after the top-dressings were applied. 
No. 5 (soot) also assumed a darker colour than the rest, but was 
not so flourishing as Nos. 1 and 2. 
When reaped (August IS, 1842), Nos. 1 and 2 were much 
the best crop to the eye — the rest being nearly equal. The straw 
and stubble upon No. 5 were quite blanched,
