REPORT OF THE SECRETARY. . 19 



The transmissions of exchanges have been in direct ratio to the 

 increase in the receipts, being for the first six months of 1885 : 



(1) Foreign exchanges: 345 boxes, representing a bulk of 2,415 cubic 

 feet, with a weight of 82,800 pounds, against 27G boxes during the same 

 period of 1884. 



(2) Domestic exchanges: 5,138 packages, this being a little above the 

 half of the total number sent out during the year 1884. 



(3) Government exchanges : 38 boxes, representing a bulk of 266 cubic 

 feet, with a weight of 10,500 pounds. 



Congressional Aid. — The Smithsonian Institution continues to receive 

 .the usual Congressional appropriation of $10,000 to carry out the op- 

 erations of the exchange service. The Library of Congress is the prin- 

 cipal beneficiary of the exchanges, large numbers of books and parcels 

 being aunually received for that institution.

expenses of the exchange service consists in the granting of free freight
