On Manures.

advantages -have been produced. In the former case, the in- 

 crease of oats was only at the rate of 6 to 1, but in the latter, 

 at that of 10 to 1, of the seed sown (* IS) ). The quantity ap- 

 plied must vary according to the soil. From 240 to 300 bushels 

 of unslaked lime per acre, may be applied on strong lands, with 

 advantage. Even 600 bushels have been laid on at once on 

 strong clays, with great success ( ai ). On light soils, a 

 much smaller quantity will answer, say from 150 to 200 

 bushels, but these small doses ought to be more frequently 

 repeated. When lime is applied to heavy clay, in order to 

 open its pores, too much can scarcely be laid on ; but when 

 applied to bogs, moorland, or moss, the quantity for the first 

 dressing, need not exceed what is usually given to other land. 

 After the moss has acquired a sward of green herbage, lime 

 is the proper manure ; but unless it be applied in moderate 

 quantities, the crop of grass will become so strong, as to lodge 

 before it is fit for cutting. The real quantity however, of cal- 

 careous matter to be used, depends upon the quality of the 

 limestone. It often happens, that five chaldrons do not fur- 

 nish more effective manure than three, because they do not con- 

 tain three-fifths of calcareous matter (* ai ). 



7. The Expense. So great is the variety, in regard to the 

 prices of lime at the kiln ; the cost attending its conveyance 

 to the field ; and that of slaking, carting, and spreading it 

 there ; and above all, in respect of the quantities necessary 

 for different soils, in different circumstances, that no accurate 

 statement can be given of the expense of liming. On the 

 whole, for unslaked lime, about Qd. per bushel may be sta- 

 ted as an average price, all charges included ; and from 120 to 

 300 bushels, as the quantity required, per statute acre. The 

 following table will then furnish some general idea of the pro- 

 bable expense :
