of Manures Applied to Pasture.

and to adopt a figure which, taking one year with another, it 

 is reasonably certain will be realised in practice, and this, I 

 am satisfied, has been done. Moreover, it will be seen that 

 at Cockle Park it brings the butcher's valuation into very 

 close agreement with the other results. (See p. 5.) 



In the reports that have hitherto appeared on the English 

 stations the cost of the cake and manures has varied some- 

 what from place to place. This is partly accounted for by 

 the fact that the manuring at Cockle Park did not fall in the 

 same years as at the other stations, and partly by the fact 

 that prices naturally vary somewhat in different parts of the 

 country. This is especially the case with common lime, 

 which can be bought at some 12s. per ton in the North of 

 England, whereas it costs about double this amount in Hants. 

 But there are obvious advantages in putting the materials 

 at the same price at all the English stations, and the following- 

 rates have been adopted as a reasonable average, the dressings 

 being calculated on this basis : — 



The prices affixed by the Highland Society and by Professor 

 Wright in the case of the Scottish stations have been 

 retained. 



At the English stations, where a preliminary year's grazing 

 was undertaken before the plots were dressed, the natural 

 variations of the plots were not considered to fall outside 

 the limits of experimental error. In the Scottish series of 

 trials conducted by the Highland Society and the West of 

 Scotland College of Agriculture, it was determined to base 

 all the calculations of the results in the actual years of experi- 

 ment on the variations as disclosed by the preliminary 

 season's grazing. It is impossible to say which is the more 

 reliable method of procedure, but in any case the main results 

 would not be disturbed were the one system substituted for 

 the other.
