as basic slag, while when added to basic slag it gave no increase 

 over the basic slag alone. 



With another seed mixture the three forms of treatment gave 

 results almost identical with the above in the first year's hay crop. 



This experiment was continued for many years, the manuring 

 being repeated every third year. The average annual results for 

 eleven years were as follows : — 



A and B differed from each other only in the fact that seed 

 mixture B contained 4 lb. per acre of wild white clover seed in 

 addition to the seeds included in A. 



These results obtained over a period of eleven years are doubly 

 interesting, as they show the effects both of proper manuring 

 and also the great difference obtained by the use of two different 

 seed mixtures. 



In the case of seed mixture A. there was a difference of 

 19J cwt. per acre per annum, on the average of eleven years, 

 betweeen the no manure plot and Plot 3, and in the case of seed 

 mixture B. a difference of 24§ cwt. per acre per annum between 

 the unmanured plot and Plot 1, but the differences between the 

 manured plots were relatively small. The average difference of 

 3 J cwt. per acre is. however, not negligible, and the fact that 

 the combined dressing of farmyard manure and basic slag did not 

 give very appreciable increases over the plots on which each: 

 was used separately is important. 



The Importance of the Seed Mixture. — The above experi- 

 ments emphasise the importance of using the best seed mixture. 

 In the first year's hay crop, there was very little difference 

 between mixtures A and B where basic slag had been used, but 

 the addition of 4 lb. per acre of wild white clover seed resulted 

 m an increase of 9 } cwt. of hay per acre with farmyard manure, 

 and an increase of 11J cwt. per acre with no manure. Over 

 the eleven years the 4 lb. per acre of wild white clover gave a 

 handsome profit, equal to ;£4 7s. per acre per annum on 

 the basic slag plots at present prices of slag and wild white clover. 

 Much smaller quantities of wild white clover than 41b. are quite 

 effective with proper manuring. 



Experiments carried out in North Wales and elsewhere 

 also prove the great superiority of wild white clover 

 seed over ordinary white Dutch clover seed in the forma-
