80 On Plaister of Paris. 



and does not answer on lands which have been long 

 under tilla^^e." 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 w^ill 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 is, 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 v/e 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
