If we consider the east half by itself we have still more perplex¬ 
ing results; we have one plot without any fertilizer which yielded 
7.2 tons per acre, one plot with stockyard manure, 20 tons to the 
acre, with a yield of 11.3 tons, two that receive phosphoric acid, 
potash and nitrogen with yields of 11.6 and 6.5 tons, two that re¬ 
ceived phosphoric acid and nitrogen with yields of 9.7 and 7.4 tons, 
two that received phosphoric acid and potash with yields of 10.6 and 
8.6 tons, two that had received phosphoric acid, potash, nitrogen 
and lime with yields of 9.3 and 8.9 tons, two that had received waste 
lime in different amounts with yields of 10.4 and 6.4 tons. In one- 
half of the cases the minerals were applied in conjunction with and 
in the other half without stockyard manure. In regard to the effect 
of any or all of the combinations of the fertilizers used upon the 
tonnage no one, I think, would be willing to say more than this, that 
taking the east and west halves separately the plot that received the 
addition of nothing made the smallest return except in one case in 
each half, but the aggregate result in regard to tonnage shows an 
advantage accruing from the application of fertilizers, but this is 
neither large enough nor uniform enough to satisfy any one, besides,
