The relation of rainfall to the degree of harmfulness of borax to 
cotton is apparent from a study of Tables 15 and 16, and this has 
been considered in detail in an earlier paper.’ 
From the results of 
the experiment as a whole it will be observed that 5 pounds of borax 
per acre produced some injury to cotton when applied in the rows, 
and larger quantities showed even greater toxic effects. The results 
are in harmony with those obtained at Arlington, Va., showing that
