SPECIFICATIONS. 



Materials to be weighed and mixed with, greatest possible care 

 and accuracy, put in eighteen bags numbered as above, and each 

 bag furnished with a label stating number and contents per sched- 

 ule above. Minimum percentages as below. 



Muriate of Soda to contain 16^ nitrogen ; Sulphate of Ammo- 

 nia, 21^ nitrogen ; Dried Blood, 11^^ nitrogen. 



Superphosphate (dissolved bone-black) to contain 15^ of soluble, 

 and 16^ total phosphoric acid. 



Muriate of Potash to contain 50^ of potash. 



No. 6, the mixture of Superphosphate and Muriate of Potash, 

 is designated as " Mixed minerals." This is duplicated in Nos. 6a, 

 6b, and 6c. The same mixture forms the basis of Nos. 7 to 15 

 inclusive, which consist of " Mixed minerals," with the addition of 

 nitrogen compounds.
