0.50 per cent. In 121 of these cases, the deficiency was less than 
0.5 per cent. | 
In 110 cases among the 578 brands of complete fertilizers the 
potash was contained in the form of sulphate free from an excess 
of chlorides. 
(5) The retail selling price of the complete fertilizers varied 
from $15 to $45 a ton and averaged $27.65. The retail cost of 
the separate ingredients unmixed averaged $18.52, or $9.13 less 
than the selling price. ° 
’ INTRODUCTION. 
NUMBER AND KINDS OF FERTILIZERS. 
During the spring of 1898, the Station’s collecting agents 
visited 206 towns between March 23 and June 8, obtaining 1,183 
samples of commercial fertilizers. These samples represent 739 
different brands, the product of 123 different manufacturers, each 
manufacturer being represented by from 1 to 49 brands. 
The subjoined tabulated statement indicates the different 
classes included in the collection.

From these figures it can be seen that 78 per cent of the com- 
mercial fertilizers offered for sale during the spring consisted of 
complete fertilizers. The remaining 22 per cent was distributed 
in nearly equal proportions between acid phosphates, bone and 
mixtures containing acid phosphate and potash.
