These facts seem to show that there is an intimate connec¬ 
tion between the crop and the soil, but the limitation of hop 
cultivation is not entirely dependant upon this cause, as it 
must be remembered that the growing of hops is quite a 
local business—both the farmers and their men have been 
brought up to the business, and therefore however suitable 
soil may be for hops, if far removed from what may be termed 
hop centres, it would be difficult to establish hop gardens in 
them-—unless by the migration of hop planters, a matter not 
easily brought about. Were this so, we should be inclined 
to think that as even the Chalk and Green Sands extend 
into Dorset, if these deposits were necessary to the hop, no 
county would be more suitable, though we are not prepared 
to say whether the prevailing moist atmosphere of this 
“ county of the mist” would be to its advantage or otherwise.
