The avei'.'igo value calculated from the analyses of the 

 twenty-six fertilizers of the first series was §4-5.01 per ton, 

 while the average of the last half of the second saries, those 

 last made, is $58.95, an increase of thirty-throe and one-third 

 per cent. This result is in perfect keeping with similar 

 cases the conntrj' and countries tlirough ; wherever the fer- 

 tilizers sold have from time to time been subjected to chem- 

 ical analysis, the quality of the fertilizers has steaM'y 

 improved, the good growing better, and the comparatively 

 worthless dropping oat of the market.
