conditions if the salt were apolied a considerable time 
before planting a large part of it mizsht be lost by leaching 
as it is very soluble. Also nitrogen,( or the same effect 
may be procured as is given by sodium nitrate ) may be 
applied in ereen manure and stable manure, bout for vest 
results these materials should be ap lied some time before 
planting to allow them to decay some what, and thus liberate 
some ot the stored up plant food. Also lime should be 
applied. in this case it apparently aids nitrifieation, 
for when applied with sodium nitrate it does not produce 
any marked increase, but when applied with green manure 
and stable manure the good effects of these fertilizers 
are greatly enhanced, Lime also »robvably has other 
actions for when applied by itself it  jroduces beneficial 
results. 
Practically then directions may be given as rollows: 
Apply lime sometime before vlanting; aly sodium nitrate 
at the time of planting as a souree of nitrogen, or with 
the same object in view, apply stable manure or green manure 
some time before jlanting. 
From what the writer knows of this soil it seems, that 
if good physical condition is secured, good cultivation 
given, humus increased, and lime applied, the Dunkirk Clay 
Will improve, give good crops, and as tine goes on sO im ,rove 
in texture that it will be no very hard task to handle it.
