been designated as high grade, between S18.00 and $24.00 per ton 

 medium grade, and below $18.00 per ton low grade. The following 

 table shows a comparison of the three grades of fertilizer in relation 

 to retail cash price, calculated commercial value and money differ- 

 ence between cash price and commercial value. 



The above table shows: 



(1). That on the average the complete mixed fertilizers have 

 cost about 12 cents more per ton than for 1913. 



(2). That the average calculated commercial value of plant 

 food in a ton has been 52 cents less than for the previous season. 



(3). That the percentage excess of the selling price over the 

 calculated commercial value of plant food in the low grade fertilizers 

 is almost three times more than in the high grade goods and is about 

 double that in the medium grade fertilizers. 



(4). That with a 30.7 per cent advance in price over the low 

 grade fertilizers, the high grade furnishes about 94.1 per cent increase 

 in commercial plant food value. 



(5). The money difference between the average selling price 

 and the average commercial valuation in the high grade fertilizers is 

 $4.74 less than in the low grade goods.
