carefully destroying the leaves, haulm, and tubers of diseasl 
plants, and not to plant potatoes again for some time on grouf 
where plants have been blighted. 
All sorts of potatoes are liable to be attacked, though e»l 
sorts frequently escape, because the disease rarely appears unl 
late in July, and then after heavy rain in most cases. It ul 
asserted that there were kinds of potatoes proof against diseasl 
but the result of a competition for handsome prizes, oflFe 
in 1874 by the Council of the Royal Agricultural Society i 
England for any kind of potato that resisted the disease for thii 
years, was that all the varieties of potato supposed to have bel 
disease-proof were found to be diseased in the first year of 
trials. 
This account of vegetable culture would not be complii 
without an allusion to the application of town-sewage by irrifi 
tion to the growth of vegetables. The sewage of towns, wl 
must be disposed of in some way, is, under certain circumstanc 
and upon certain soils, profitably distributed upon land, either ill 
flowing naturally in carriers or in drains by gravitation, or I 
being pumped up to levels from which there is a fall. Not onlnV^ 
the organic and offensive matter retained by the land thus treatw|r 
so that the effluent water is rendered practically inoffensive, but 
some cases good profits are realised by the crops grown upon 
All the ordinary kinds of farm crops are grown, but these a 
not so profitable as vegetables, such as onions, cabbage, broco 
celery, cauliflowers, and many others, which give enormo 
yields under this treatment. The sewage farms at Romford ai 
Barking, in Essex, afford typical instances of successful mark 
gardening. In some seasons an acre of cabbages treated wi 
sewage, in quantities varying from 1500 to 2000 tons, who 
value may be from 12Z. to IG/., has realised as much as 70/ 
and greens have brought 73/. per acre. Quantities of liquid, 
afforded by the system of sewage irrigation, are essential to tl 
cultivation of vegetables which are taken in rapid successio 
and most of which are transplanted. This is particularly tl 
case in seasons of drought, when the sewage-farmer has gre 
advantages and realises high profits. Vegetables are grow 
very largely upon the sewage farms above mentioned, as we 
as upon those of Croydon, Leamington, Aldershot, Wrexhar 
Cheltenham, Edinburgh, and others ; not only are they abundan 
but excellent in quality. 
Upon the comparatively small acreage of Wales and Scotlar 
devoted to market gardening, it is not necessary to comment ; 
any length. The systems of cultivation adopted in both countrii 
are practically the same as those followed in England. 1
