In the spring brands analyzed nitrogen was absent in twenty- 
six and potash in nine samples. In those of the fall brands, 
nitrogen was absent in fourteen, available phosphoric acid in one 
and potash in seven samples. 
The following table presents the average ratios of the amount 
of each constituent found to the minimum and maximum amounts

It will be seen that upon an average the amounts of each con- 
‘stituent found present was only four per cent above the minimum 
amount guaranteed, while the maximum amount guaranteed 
averaged 27 per cent more than the amount found, also the maxi- 
mum guarantee averaged 33 per cent more than the minimum 
guarantee. 
In this connection it is worthy of remark that the results this 
year show a much nearer average approach in actual content to 
the minimum amount guaranteed than did the results last year, 
but the maximum amount apparently guaranteed is this year _
