If the value assigned by Mr. CHAPMAN to the best sample in 

 each of the four seasons in which he made a money valuation be 

 taken as 100, and the valuation of the produce of each plot be 

 expressed relatively to this for each year and then averaged, the 

 following figures are obtained, which may be taken as expressing 

 the average relative value of the various samples to the brewer :

It seems probable that the brewing value of the hops has been 

 more affected by accidental influences incidental to picking and 

 drying than by the mode of manuring. At any rate, it appears that, 

 on the whole, the hops grown with mineral manures and nitrate of 

 soda have not been inferior for brewing purposes to those grown 

 with dung alone ; indeed, the evidence tends to be in the contrary 

 direction, for in individual years the dunged plot, for brewing 

 quality, has been twice beaten by plot F, twice by plot C, twice by 

 plot D, twice by plot E, and four times by plot B. 



If the valuations made by the factors and merchants are taken 

 in the same way and stated in average percentages of the highest 

 values assigned in the individual years, we get the following 



results :
