Thus the former fertilizer is worth $14.22 a ton more 

 than the latter. Even if the latter fertiHzer were offered 

 at $28.00 at the depot at Jacksonville, it would be neces- 

 sary to decide whether one would make anything by buying 

 cheaper and having the extra hauling and handling of so 

 much more useless material. 



The Report of the State Chemist of Florida for January, 

 1909, contains the following comparison of high-grade 

 and low-grade fertilizers, which shows clearly how much 

 money has been lost by purchasing the low-grade fer- 

 tilizers : 



" I again earnestly recommend the use of the high-grade 

 mixed goods as the most economical, and again quote 

 statements made in former reports as follows: The 

 composition, selling price, and valuation of the average 

 brand of each group appear below :

" It will be noticed how rapidly the relative selling price 

 above state values decreases from the low-grade to the 

 high-grade goods. 



Low grade costs above state values 

 Medium grade costs above state values 

 High grade costs above state values
