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. INIolasses 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 a residue. 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 :
