rather unsatisfactory. Shorts, beet pulp, and beet mo- 
lasses when combined produced nearly as large gains as 
the full ration of shorts alone. By feeding one hundred 
pounds of molasses, thirty-two pounds of shorts and one 
hundred fifty-three pounds of beet pulp were saved? 
Over-feeding with molasses causes excessive scouring and 
often results in death to pigs. Molasses is not generally 
considered to be a good pig feed; if it is used, only small 
quantities should be given, and this must be introduced 
gradually into the ration. 
WASTE LIME AND MINOR BY-PRODUCTS 
Considerable lime is used to purify the juice in the 
manufacture of beet-sugar. After the lime has combined 
with the impurities, it is of no more value to the manu- 
facturer. Some factories run this refuse lime into the 
sewer; others run the lime water into large reservoirs 
where the water is allowed to evaporate, leaving the lime 
as aresidue. Lime to the extent of 2 to 6 per cent of the 
weight of the beets is required; hence, the quantity of 
waste product is large. No satisfactory commercial use 
has been found for it, although it has been used to some 
extent as a fertilizer. Its value for this purpose varies 
with the quantity of water in it, the quantity of valuable 
constituents it contains, and the nature of the soil on 
which it is to be used. The following is an analysis of 
samples from a Michigan factory :
