received into the United States through the Exchange Service during 

 the fiscal year 1911 more than doubled the weight of those sent abroad, 

 while the weight of those received during the fiscal year 1912, cov-

 is every reason, therefore, to believe that this important branch of 

 the work yields adequate returns. 



By referring to the foregoing table it will be noted that 70 per 

 cent of the work of the office has been conducted in behalf of United 

 States governmental establishments. 



Of the 2,395 boxes used in forwarding exchanges to foreign bu- 

 reaus and agencies for distribution (an increase of 15 boxes over 

 1911), 328 boxes contained full sets of United States official docu- 

 ments for authorized depositories and 2,067 were filled with depart- 

 mental and other publications for depositories of partial sets and 

 for miscellaneous correspondents. The number of boxes sent to each 

 foreign country and the dates of transmission are shown in the fol- 

 lowinff table:
