Speaking generally, the Silesian sugar-beets grown in this 
country contain the same amount of nitrogenous compounds 
and mineral matters as ordinary mangolds, and from to 5 
per cent, less water, and nearly double the amount of sugar 
which is found in common mangolds. The average per- 
centage of dry matter in sugar-beets is 1 5 5, and in common 
mangolds 11. A ton of the former, therefore, contains 
347 lbs. of dry feeding substance, in round numbers, and a 
ton of the latter only 246^ lbs. Allowing only little for the 
superiority of sugar as a fattening element of roots, the case 
is far from over-stated if 1 ton of English sugar-beets is con- 
sidered as equivalent in nutritive properties to at least Hton 
of common mangolds. In the next place, let us compare the 
preceding analyses with the average comparison of the refuse 
pulp from beet-root sugar manufactories. In round num- 
bers this may be stated with sufficient accuracy as follows :

In 100 parts of pulp it will be seen there are 30 per cent, of 
dry matter, whereas 100 of sugar-beet from which it is obtained 
contain only 15- parts of dry substance, and common man- 
golds but 1 1 parts. 
A ton of beet-root pulp accordingly contains 672 lbs. of 
dry matter, or 325 lbs. more than a corresponding weight of
