ON BEET* ROOT PULP. 
the roots, and 4254 more dry matter than 1 ton of common 
mangolds. In other words, 1 ton of pulp contains not quite, 
but nearly, the same amount of solid substances as 2 tons of 
Silesian sugar-beets, or 3 tons of common mangolds. 
Nobody probably will dispute the fact that the dry sub- 
stance of a sugar-beet or a mangold is more valuable for 
feeding and fattening purposes than the dry substance of the 
pulp. The question, however, which requires to be settled 
is, not whether the perfectly dry pulp is less valuable than 
perfectly dry roots from which it is made, but whether the 
672 lbs. of solid matter contained in a ton of pulp are worth 
more or less than the 347 lbs. of solid matter present in a 
ton of sugar-beets, or 246^- lbs. of the solid matter of which 
common mangolds consists. 
A further comparison of the preceding analyses shows that, 
weight for weight, the pulp contains more albuminous (flesh- 
forming) matter, much more fibre, and but little sugar. On 
the one hand we have in sugar-beets an excess of 8 per cent, 
of sugar, and in common mangolds an excess of 4 per cent, 
over the amount of sugar in the pulp ; and, on the other 
hand, we have 24 per cent, of fibre in the pulp against 34 in 
beets, or 3 per cent, in common mangolds, besides an excess 
of 1 per cent, of albuminous matter in the pulp. 
The question thus resolves itself into this : are 4 lbs of sugar 
(the excess in 100 to common mangolds), or 8 lbs. of sugar 
(the excess in 100 lbs. of sugar-beets), worth more or less than 
i;lb. of albuminous or flesh-forming matter and 20^- lbs. or 
or 21 lbs. of the finely grated fibre, which constitute the 
excess in 100 lbs. of the pulp. 
As the difference in the amount of nitrogenous matter in 
the pulp and in the roots is comparatively small, we need 
not lay any stress upon the excess of albuminous matter in 
the pulp, and for simplicity's sake may throw it together 
with the excess of fibre. We thus obtain in every 100 lbs. 
of pulp 21^ lbs. more of the solid matter of which the pulp 
mainly consists than we give to cattle if we fed them upon 
the same quantity of sliced beet-roots ; but against this a set- 
off has to be made in the excess of 8 lbs. of sugar in the beets, 
or 4 lbs. when compared with common mangolds. 
There can be no doubt that 1 lb. of sugar is worth more as 
a fattening material than 1 lb. of the vegetable fibre which 
constitutes the bulk of the beet-root pulp. Whether 8 lbs. of 
sugar are worth as much as 21-4 lbs. of crude fibre, we ques- 
tion very much, and have no hesitation in subscribing to the 
opinion that 22 lbs. of the fibre go further in supplying food 
than 4 lbs. of sugar. In support of this view of the matter
