(2) Effect of stable manure on percentage of sugar in beets.— 
At the Station the percentage of sugar was increased 0.5 to 3.2 
per cent with an average increase of 2 per cent. At Fayetteville 
the use of stable manure increased the percentage of sugar in four 
cases and decreased it in two cases, there being an average increase | 
of 0.7 per cent. Taking all the work at both places, there was an 
average increase of 1.5 per cent of sugar.

(3) Hffect of stable manure on coefficient of purity.— In the 
Station experiments the coefficient of purity increased in every 
case except one when stable manure was used, the increase varying 
0 to 2.6 and averaging 1.3. At Fayetteville, the coefficient of 
purity increased in three cases and decreased in three cases, there 
being an average increase of 0.9. Taking the work in both places, 
there was an average increase of 1.6.

(4) Effect of stable manure on cost of crop.— It would be a 
conservative estimate to place the cost of stable manure at $2 
a ton, including costs of drawing to field and applying. ‘The ap- 
plication of 20 tons would, therefore, cost $40 an acre.
