The figures in the last column speak for themselves and at once show how the cost 

 of similar treatments may vary in different places in the same State. 



* At Kobbinsville only three applications were made, except on the sulphur-zinc arsenite 

 plots, where those of Series I and II received four treatments, as also 16 rows of the 

 corresponding plot in Series III. In all other cases four applications were made.
