REPORT ON THE INTERNATIONAL EXCHANGES. 



Sir : I have the honor to submit the following report on the opera- 

 tions of the International Exchange Service during the fiscal year 

 ending June 30, 1918 : 



The estimate submitted by the Institution for carrying on the 

 service during the year was $35,000. This amount was granted by 

 Congress, and, in addition, an allotment of $200 was made for print- 

 ing and binding. The various governmental departments and other 

 establishments paid the Smithsonian Institution for the transporta- 

 tion of exchanges $2,345.18, thus making the total available resources 

 for carrying on the sj'stem of exchanges $37,515.18. 



The total number of packages handled during the year 1918 was 

 266,946. The weight of these packages was 182,825 pounds. 



The number and weight of the packages of different classes are 

 indicated in the following table:

 those received is not so great as indicated by the figures in the fore- 

 going table. Packages sent abroad usually contain only a single 

 publication each, while those received in return often comprise sev- 

 eral volumes. It is also a fact that many returns for publications 

 sent abroad reach their destinations direct by mail and not through 

 the exchange service. 



So far as the Institution has been advised, only three consign- 

 ments of exchanges have been lost through hostile action since the
