Now, without pretending that any very nice conclusions are to 
be drawn as to the relative advantages of one grain crop over 
another, which would seem, according to the average crops 
assumed in this case, to be nearly equal, or perhaps even of one 
root crop over another, unless when the difference is very remark- 
able, there is one very striking result in the vast excess of nourish- 
ment of the root over the seed crop. Thus the white turnip, 
which is the lowest in the scale of roots, gives twice as much 
nourishment per acre as the highest in the scale of grains ; and 
the carrot, which is the highest of the root crops, gives nearly five 
times as much as barley and beans, which are the lowest of grain 
* There is no equivalent given for bean-straw ; nor can I find, in any of 
the tables, its probable value from the azote contained. The value of all 
straw for fodder must depend oa the mode in which it is harvested. In 
Scotland, the order in which the farmer places his stiaw for foddef is — 
1st, pea; 2nd, bean; 3rd, oat; 4th, wheat ; 5tli, barley: while in England, 
where the bean is quite withered before it is cut, it stands last in the scale. 
Not to place it too low, I have adopted the same equivalent as that of wheat 
(viz. 450), which represents the least valuable of any straw, while that of 
barley is 300. This value, as between wheat and barley, neither accords 
with that indicated by the azote which they respectively contain, nor, I think, 
with that usually attached to them in practice ; but it should be observed 
that, ill comparing the general value of these crops, the difference can never 
be great which results from equivalents varying only from 300 to 500, as 
(with the exception of that of peas) is the case with all these straws where 
the average quantity per acre is never much below 1 ton, nor above 2. In 
calculating accurately the relative values of different straw as fodder, of 
course this difference becomes of more importance. It is remarkable in the 
seed-crops, that the greater or less quantities per acre, or equivalents of 
value either in seed or straw, seem so nicely to balance one another, that, on 
the total produce per acre, the quantity of nourishment only varies from 
about 42* in beans and barley, to 54 'G iu wheat. — W. H. H.
