and does not answer on lands which have been long 
under tillage.” We find the direct contrary effects here. 
It is true we do not lime here, nearly as highly as they 
do in England. Our lands will not bear so much lime 
as theirs. We have as good and as bad land, as that of 
any part of the world. The poorer the land, the less 
lime it will bear. But our best land will not admit of 
so much lime at two dressings,* as I have understood 
they put on in England, at once. Whether our lime is 
stronger, or our climate less favourable to it, I cannot 
tell. A difference of climate may have an operation 
on plaister, as it has on products. Vegetation is here 
more rapid than that of England, and of course our 
harvests earlier. The straw of their wheat 1s, I believe, 
generally shorter than that on our fresh or manured lands, 
and the ears larger and fuller, where the wheat is good; 
for they are not without a due proportion of bad wheat, — 
with light and small grains. So that we do not generally 
get so much wheat off an acre, as they do. But our 
wheat yields a greater proportion of flour. It is not so 
flinty, is thinner skinned, and of course we have less 
offal and more flour. Our grain grinds more lively, 
and without kiln drying. Much of their wheat requires 
kiln drying, before it can be ground to advantage, and 
especially grain intended for exportation; owing to its 
qualities, produced by moisture and other circumstan- 
ces of climate. In Ireland their grain, ground at their 
best mills, is generally kiln dryed. We know neither 
the necessity nor use of kilns in our mills, except for

*I might have said three or four dressings. Land ever limed, or limed too often, may be restored, 
by green manures ploughed in, er dung. R. P.
