It is admittedly difficult to have each fertilizer mixture alwaj's comply wdth each 

 of the guarantees. The fact that so few have fallen below the guarantee in commercial 

 valuation is worthy of commendation. 



The following additional statistics with reference to mixed fertilizers are recorded, 

 the 1921 figures being given for comparison: — 



Only 8 brands of mixed complete fertilizer, about 2 per cent of the whole number 

 analyzed, showed a commercial shortage of $1 or over per ton. This is a much better 

 showing than last year, when 21 brands (7| per cent of the w^hole) were commercially 

 deficient to this extent. No ammoniated superphosphates or superphosphates with 

 potash were found seriously deficient commerciallj- during 1922.
