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 banljs in rich soil or on fertile 
slopes, where irrigation could be effected, particularly so 
within our territory along the river valleys of Gipps 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 Eiver, 
in Gipps Laud, 1500 lbs. 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.
