Sewage- Farming. 
sewage-grown cabbage were bouglit at once for 14(?. per dozen ; 
the remainder went off very slowly, first at Sd., then at 6c?., per 
dozen, and were with much delay disposed of. There should be 
no difficulty in growing 40 or 50 tons of the large cattle-cabbage 
to the acre, and such a yield would afford an ample return to 
the grower. 
It is almost needless to say that Carrots and Parsnips are 
easily cultivated, and that very large crops of them have been 
obtained. 
Potatoes, — The cultivation of this plant has much increased 
of late years upon sewage-farms. Its ready sale and facility of 
storing will account for this, and though ; on the one hand, we 
have no evidence of the production of superior crops under irri- 
gation to those obtained by other means, it does not seem, on 
the other hand, that this mode of cultivation renders the plant 
more subject to disease. Perhaps we have hardly experience 
enough, at present, upon the latter point ; but, on two well- 
known sewage-farms at least, I have been assured that a diseased 
tuber has not been seen, though its cultivation has proceeded for 
some years. The short time that the early varieties occupy 
the land should render them objects of special attention to the 
sewage-farmer, and he will probably find it to his advantage in 
many cases to substitute a certain breadth of potatoes for some of 
the above-mentioned crops. I shall have occasion to allude to 
this subject further on, and as the cultivation of this plant under 
sewage in no way differs from its ordinary culture, 1 need only 
thus briefly call attention to its utility to the sewage-irrigator. 
Cereals. — I now turn to the cultivation of Cereals, and the con- 
sideration of the question whether they can take their place in the 
routine of an irrigated farm. The attention of those interested has 
for some time past been given to this problem, for upon it hangs 
another connected closely therewith, and one which some day or 
other must force itself into prominence. Unless grain crops 
can be cultivated successfully, I confess I do not look upon the 
establishment of sewage-farms on an extensive scale with any very 
sanguine expectations of immediate success. The keeping of large 
numbers of stock must, I am persuaded, eventually become a 
chief part of the business of the sewage-farmer upon all extensive 
occupations ; but without straw this would be impossible. More- 
over, I firmly believe that the use of sewage as an auxiliary 
to other manures will extend, and that farmyard-dung will be 
hardly less valued by the sewage-farmer than by the ordinary 
agriculturist. There are certain crops (onions, for instance) 
which have already proved their partiality for such a mixture ; 
and it is plain [that on many descriptions of soil (though perhaps
