Press Opinions. 



" The subject is dealt with fully in every little detail ; consequently, even the veriest tyro can 

 take away some useful information from its pages." Irish Farming World. 



"Farmers are but little given to reading: but nowadays brewers have to study their trade 

 and keep abreast of its every aspect, and as far as regards our trade, to them this book 

 especially appeals, and will be especially useful." Licensed Victuallers' Gazette. 



" Like an oasis in the desert comes a volume upon the above subject, by the Professor at 

 the Higher Agricultural College, Tetschen-Liebwerd, Germany, who has been fortunate 

 enough to obtain an excellent translator from the German in the person of Mr. Charles 

 Salter. The paucity of works upon the history and cultivation of hops is surprising con- 

 sidering the scope it gives for an interesting and useful work." Hereford Tinu's. 



"We can safely say that this book deals more comprehensively and thoroughly with the 

 -subject of hops than any work previously published in this country. . . . No one interested in 

 the hop industry can fail to extract a large amount of information from Professor Gross's 

 pages, which, although primarily intended for Continental readers, yet bear very closely on 

 what may be termed the cosmopolitan aspects of the science of hop production." South 

 Eastern Gazette. 



"This is, in our opinion, the most scholarly and exhaustive treatise on the subject of hops, 

 their culture and preservation, etc., that has been published, and to the hop grower especially 

 will its information and recommendations prove valuable. Brewers, too, will find the chapter 

 devoted to 'Judging the Value of Hops' full of useful hints, while the whole scope and tenor of 

 the book bear testimony to the studious and careful manner in which its contents have been 

 elaboratec'." Hn'it'c: -;' /< :
