EXPLANATION OF THE TABLES OF ANALYSES. The 

 mixed fertilizers have been p;rouped in the tables as in preceding 

 years. One section contains the brands which carry nitrogen, phos- 

 phoric acid and potash; the other section, those fertilizers which 

 carry nitrogen and phosphoric acid. Both are arranged alphabeti- 

 cally according to manufacturer's name, as well as brand name. The 

 nitrogen is given in its various forms as follows: as nitrates and 

 ammoniates, water soluble organic, water insoluble organic and total. 

 The quality of the water insoluble organic nitrogen is indicated by 

 the words "passed" and "inferior." The word "passed" indicates 

 that the brand carries its water insoluble nitrogen in a satisfactory 

 form, while the word "inferior" indicates the use of inferior forms of 

 organic ammoniates. The column headed " Guarantee Substantially 

 Met (?)" will indicate at a glance whether any particular brand 

 suffers a commercial shortage. Wherever the guarantee is substan- 

 tially met the word "Yes" has been used, while brands showing a 

 serious commercial shortage have been designated by the word 

 "No." The arrangement of the remainder of the tables is the same 

 as in preceding years, and is self-explanatory.
