545. There are several varieties, of which the Farnham, the 

 Golding, the Yellow Grape, are considered the best. 



These are found to differ much in the proportion of their in 

 organic constituents, and consequently the above analyses must 

 only be considered as an approximation as regards the species, 

 while it is accurate as regards one variety. (See Stephen s Far 

 mer s Guide, vol. , p. 45, 320J 



546. Tho soil peculiarly adapted to this plant is a rich, deep, 

 rather adhesive clay, with abundance of organic matter, or veg 

 etable mould ; and a porous rocky subsoil. A dry subsoil is 

 considered essential. The variety grown, and the quality of the 

 produce depend entirely upon the character of the soil ; and the 

 peculiarities from these causes are almost as numerous as they 

 are in wine-culture. In England, large quantities of valuable 

 manure are expended on hops ; such as bones, woollen rags, &c.
