Humulus Lupulus, L.* 



The Hop-plant. Temperate zone of Europe, Asia and North 

 America. This twining perennial unisexual plant has proved 

 to yield enormously on river banks in rich soil or on fertile 

 slopes, where irrigation could be effected, particularly so 

 within our territory along the river valleys of Gripps Land 

 and in other similar localities. A pervious especially alluvial 

 soil, fertile through manure or otherwise, appliances for 

 irrigation natural or artificial, and also shelter against storms 

 are some of the conditions for success in hop-growth, and 

 under such conditions the rearing of hops will prove thus 

 ' far profitable in countries and localities of very different 

 mean temperature. A dry summer-season is favorable to 

 the ripening and gathering of hops. On the Mitchell River, 

 in Gipps Land, 1500 Ibs. have been obtained from an acre. 

 In Tasmania large crops have been realized for very many 

 years. The plant might be readily naturalized on river 

 banks and in forest valleys. The scaly fruit cones form the 

 commercial hops, whose value largely depends on the minute 

 glandular granules of Lupuline. Hops impart their flavor 

 to beer, and principally by their tannic acid prevent acetous 

 fermentation and precipitate albuminous substances from 

 the malt. Hop-pillows are recommended to overcome want 

 of sleep. Many of the substitutes of hops are objectionable 

 or deleterious. The refuse hops of breweries possess double 

 the value of stable manure. Active principles of hop 

 leaves and fruits: A peculiar volatile and a bitter acid 

 substance. The fibre of the stem can be made into cords 

 and paper.
