lectors should be Sent out to visit miueral localities. The expense of 

 such work is tritiinji in comparison with the results to be attained. 



In connection with uiy work in the Geological Survey I myself made 

 two expeditions into the field — tirst, to the tourmaline region of Western 

 Maine, and, second, to the feldspar quarries near Middletown, Conn.; 

 and both trips yielded good material for the Museum. Assistant Chem 

 ist T. M. Chatard also went twice to the corundum tields of North Caro- 

 lina and biought back good collections. Part of the latter have already 

 been turned over to the Museum aud part have been reserved for lab- 

 oratory investigations. Minerals have also been received from other 

 Geological Survey parties, and notably from Messrs. J. B. Marcou, C. 

 D. Walcott, and J. S. Curtis. Mr. Marcou, in particular, obtained for 

 the Museum a large number of specimens of the vivianite from Mullica 

 Hill. N. J. ; and Mr. Whitman Cross sent in a collection of the zeolites 

 frt»m Table Mountain, Colorado, and the cryolite minerals found near 

 Pike's Peak. 



Early in the year our exchange system began to bear fruit, and the 

 following are among the more noteworthy accessions derived from this 

 source: From N. H. Perry, of South Paris, Me., we received a collection 

 of the lepidolites, tourmalines, «&c., of Auburn, Me., the topaz and as- 

 sociated minerals of Stoneham, Me., the cancrinite and sodalite from 

 Litchtield, Me., and other material from the same region; from E. M. 

 Bailey. Andover, Me., a collection of the lei)idolite, &c., from the new 

 locality on Black Mountain, in Rumford, Me.; from Prof. W^. N. Kice, of 

 Wesleyan University, a fine series of the minerals found in the feldspar 

 quarries near Middletown, Conn. ; from G. F. Kuuz, a very full set of 

 the rarer titanium minerals of Magnet Cove, Ark.; from J. Siemachko, 

 St. Petersburg, a inimber of rare Russian minerals ; and from W^ard & 

 Howell, of Rochester, N. Y., a number of valuable specimens, repre- 

 senting various localities, among them a good specimen of Japanese 

 >tibuite. Still other exchanges have been arranged for, but the collec 

 tious have not yet been actually received. 



Our meteorite collection is small as yet, but has shown some growth 

 during the year. From Ur. J. Berrien Lindsley, of Nashville, we have 

 received a fine slice of the meteoric iron from Robertson County, Ten- 

 nessee. We have also obtained, by exchange, cuttings of the Dalton, 

 Ouachita and Tazewell irons, and meteoric stones from the Iowa County, 

 Mocs and Pultusk falls. The large meteoric iron, weighing 53 kilo- 

 grams, recently discovered at Grand Rapids, Mich., has been, through 

 the kindness of Prof. J. R. Eastman, deposited in the Museum for ex- 

 hibition aud descrii)tiou. 



In April the work of installing the mineial collection was begun in 

 the west-south range, but was soon interrupted by the labors involved 

 in ))re])aration for the New Orleans Exjjositiou. The Willcox collection, 

 however, has been arranged and labeled, and 1,055 specimens of the 

 Museum collection proper are now on view. The plan of arrangement
