to Mr. Alfred C. Chapman, F.I.C., of 23, Leadenhall Street, 

 London, a gentleman of well-known chemical authority in 

 connection with brewing matters, in order that he might 

 make comparative analyses of them and assign to them 

 their relative value as judged from the standpoint of the 

 brewer. The duplicate set of samples was submitted to a 

 well-known firm of hop factors, also with a request to 

 classify them in their order of merit from a market point of 

 view. The samples were submitted for judgment in each 

 case under cipher numbers which afforded no clue to their 

 origin. 



We have, therefore, for the last two years, in addition to 

 merely quantitative yields, the scientific verdict of the brewing 

 chemist, and what may be called the market verdict of the 

 hop factor ; snd it is interesting to compare both the results, 

 the one for a season in which the crop showed itself to be 

 almost wholly dependent, as regards quantity, on the manure 

 supplied to it, and the other for a season in which the hop 

 plant, although not altogether ungrateful for manure, could 

 nevertheless have got on fairly well without it. In such 

 a season as the last it is obviously doubly interesting to 

 ascertain the effect of the manure on quality. 



I will first give the results of the chemical analyses of the 

 hops for the two years, viz., determinations of total resins 

 and of soft resin. The results of modern investigation tend 

 to show that it is very largely to the presence and proportion 

 of the latter that hops owe their preserving value, though the 

 quality of hops is by no means wholly dependent on this one 

 feature.
