of view of weight nor of butcher's valuation has this 

 substance been used profitably. Its effects on the weight of 

 hay have been rather more pronounced, but here also its 

 use has left no profit. It has increased the fescues and 

 Yorkshire fog, but has had little influence on the other 

 plants. The joint report of the butcher and wool-expert is as 

 follows : — "Two very good sheep, others much back. Wool 

 3lbs. per sheep, like No. 7 as regards quantity and quality." 



Plot 10. — The Effects of Dissolved Bones. — This manure 

 (6 cwt. per acre] was applied in the spring of 1897, anc ^ 

 contained the same amount of phosphoric acid as the super 

 of Plot 9. As regards nitrogen the dissolved bones have 

 supplied one half as much as the sulphate of ammonia of 

 Plot 9. On the aggregate of the three years the yield of hay 

 of Plots 9 and 10 has been the same, but as the dissolved 

 bones cost less than the mixture of super and sulphate of 

 ammonia the net profit from the former has been greater. 



There are no very striking differences in the botanical 

 composition of the herbage. 



As in the case of the hay, so in the case of the mutton, the 

 yields from Plots 9 and 10 are identical. The less cost of 

 the dissolved bones has, however, produced a better net 

 return from their use, and this is also borne out by the 

 butcher s valuation. So far, however, the effects do not 

 ' compare favourably with slag or superphosphate used 

 alone. 



The joint report of the butcher and wool-expert is as 

 follows : — " Sheep 1 of fair quality and in good thriving 

 condition, but rather deficient in weight. Three were prime 

 fat. Wool of fine quality, but not abundant — -2 Jibs, per 

 sheep/' 



In the article that r.ppearedin this Journal in December, 1 898. 

 attention was called to the fact that the weight of pasture 

 calculated as hay, necessary to give ilb. of live-weight increase 

 may vary greatly under different systems of manurial 

 treatment. 



In Table IV. the subject is dealt with for the three years the 

 experiment has been in progress. On account of the fact
