The farmer need not learn from this or any other table the 
importance of a turnip-crop, it being acknowledged by all that it 
is indeed the sheet-anchor of light-soil cultivation; for although 
the per centage of nutritious matters is trifling in the turnips, 
when compared with that of peas, beans, oats, or barley, yet the 
immense weight of these roots which can be grown — sometimes 
as much as 40 or 50 tons per acre — gives such a very large quan- 
tity of nutritious matters, that swede turnips* may well be called 
the raw material for the manufacture of beef. The farmer will 
also see the peculiar adaptation of the carrot crop to the rearing 
and fattening of stock — the nutritious matters which they contain 
being greater than turnips, and being admirably fitted for the 
heavier description of soils, where turnips cannot be success- 
fully cultivated. He will also see, from the immense weight 
of water contained in those roots, that it is desirable to give some 
dry provender to his sheep, such as oat or barley meal, oat-straw, 
hay, or pea-haulm, which would prevent the frequent scouring of 
those animals, the consequence of so much watery food ; and by 
occasioning the food to remain longer in their stomachs, a greater 
quantity of nourishment would probably be obtained than when 
eaten alone. 
27. The hay-crop varies very considerably in its per centage of 
nutritious matters — more so, we believe, than any other ; the con- 
sequence of difference of soil, and methods adojited in saving. 
In the blades and stems of the young grasses there is much 
sugar, which, as they grow up, is gradually changed, first into 
starch, and then into woody fibre ; and the more comj)letely the 
latter change is effected, the riper the plant becomes, and conse- 
I have not been able to obtain a correct analysis of (lie Swede turnip.
