< Average of analyses showed 5.56 per cent acid soluble potash, 16.33 per cent water, and 11.52 per cent insoluble 

 earthy matter.

The analyses of those fertilizing materials valued chiefly for their nitrogen are given 

 in the following tables. Averages are given when more than one analysis was made 

 of any brand. Boldface type represents serious deficiencies.
