GOVERNMENT DOCUMENTS. 



The first action by Congress relating to an international exchange of 

 official publications was a joint resolution, July 20, 1840 {SUifntes at 

 Large, vol. v, i>. 509), authorizing the Librarian of Congress, under the 

 direction of the Committee on the Library, " to exchange such dujdi- 

 cates as may be in the library for other books," and to exchange, in the 

 same manner, public documents, of which "fifty additional coi>ies" were 

 ordered to be [)rinted for the i)urpose. Sui)plementary acts were passed 

 March 4, 1S4G; June 2G, 1848; June oO, 1848; March 2, 1849; August 

 .SI, 1852; August 18, 185<;; March 2, 18G7. 



The last Congressional action was taken on July 25, 18GS, in the fol- 

 lowing terms :

*The apparent decrease in the cost of exchanges for the fiscal year 1885-86 is duo, 

 to the re-imbursemeut during that year of a check for $2,498 lost in the mails In the 

 year 1884-85. It was charged to the first six ninntlis of 1885, and thus increases the 

 cost of exchanges for that period and diminishes that for the year 1885-'86 by credit 

 for re-iuibursement.
