At the request of the Baltimore and Ohio Railroad Dr. E. A. Back has made 
several trips to Baltimore to cooperate with the company's chemist and 
elevator superintendent. Grain arriving at Baltimore this year is more 
heavily infested with insects than usual. Formerly the railroads at Baltimore 
have been paying private concerns 34 cents a bushel for funigating grain in cers 
and vessels. The railroads have determined to do this work for themselves 
at a charge to the grain owners of from 1/2 to 3/4 of a cent per bushel. 
With cars holding on an average about 1,500 bushels of wheat one can readily 
estimate the saving to shippers effected by this change of policy. At a 
_ charge of 1/2 cent per bushel the saving to grain shippers is the difference 
between $7450 and S526 50.
