EXCHANGES AND TRANSPORTATION. 



The system of exchanges has been in a highly successful condition during 

 1863, both the receipts and transmissions being fully equal to the average of 

 any previous year. The attendant expenses of this branch of operations are, 

 however, great and increasing, and would long since have become almost pro- 

 hibitory but for the liberality exhibited by various transportation companies in 

 carrying the boxes and parcels of the Institution free of any charges for freight. It 

 is not too much to say that thousands of dollars arc thus presented by the com- 

 panies as a recognition on their part of the great importance, domestic as well 

 as international, of these operations of the Institution. Among the parties de- 

 serving of especial mention in this connexion are the proprietors of the Cunard 

 steamers between New York and Liverpool, and New York and Havana ; the 

 North German Lloyd, between New York and Bremen ; the Hamburg American 

 Packet Company, between New York and Hambiu'g ; the Panama Railroad 

 Company ; the Pacific Mail Steamship Company ; the Hudson's Bay Company ; 

 the Adams Express Company, &c.
