very nearly the same (10 cents per pound) whether it be contained in 
the highest grade samples or in those of the lower grades, something

the impurities with which the lower grades are admixed. 
The cost of importing superphosphates from England will appear 
from the following statements and estimates. It will be noticed that 
the first statement refers to an actual importation :—
