from the mill. Most of it goes into huge lumber-lined 
earth| silos six to ten feet deep, where it ferments into 
the pulp that is ordinarily fed. An increasing number of 
factories is being equipped with drying plants into which 
the pulp goes after a part of the water is expressed by 
pressure. In afew minutes the pulp is reduced to a mois- 
ture-content of about 10 per cent, after which it is sacked 
for shipment, or is mixed with molasses before being sent 
to market. 
By drying pulp, the loss due to fermentation is avoided 
and a concentrated feed is made. About 5 to 6 per cent 
of the original weight of the beets is recovered in drying. 
Dried pulp is somewhat similar to corn or to cornmeal 
in composition and in feeding value. In this form it is 
worth about ten times as much as the fresh pulp and 
about eight times as much as the siloed pulp. 
Uses of beet pulp. 
It is often necessary to starve stock for a few days in 
order to induce them to eat siloed pulp for the first time ; 
but once they acquire the taste for it, all classes of live- 
stock eat it readily. Although siloing gives to pulp a dis- 
agreeable odor, it is a better feed after fermentation than 
before. The value of pulp lies not only in its succulent 
nature, as with corn silage, but it also has a desirable 
hygienic effect. Brood animals and dairy cattle are es- 
pecially benefited by the laxative properties of the pulp. 
Jt has a stimulating effect on the digestion of all animals 
and enables them to make the most of their feed. Wet 
pulp is almost an ideal feed in sections where alfalfa forms 
the roughage part of the ration. Where grain can be ob-
