Department of Maps and Charts. — The work of pre- 

 paring and classifying the Museum's large collection of maps 

 has been continued by Dr. Woodward. A large part of the 

 collection is now available for use, having been placed in 

 convenient holders, arranged by subjects, as under states, 

 counties, etc., so as to be readily accessible. Several maps of 

 great rarity are contained in the collection, which now ranks 

 as fourth in importance in New York City. Much use of the 

 collection has been made during the past year, even by per- 

 sons outside of the Museum Staff. 



Important donations have been received from Gen. J. 

 Watts de Peyster, Dr. H. C. Bumpus, Prof. H. F. Osborn,
