REPORT OF LEPARTMEN1 OF MINERALOGY, 223 



lectors should be sent out to visit mineral localities. The expense of 

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



En connection with my work in the Geological Survey I myself made 

 two expeditions Into the field — first, to the tourmaline region of Western 

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

 and both trips yielded good materia] for the Museum. Assistant Chem 

 si T. M. < Jhatard also went twice to the corundum fields of North < Jaro- 

 lina and brought hack good collections. Pari of the latter have already 

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

 oratory investigations. Minerals have also been received from Other 

 Geological Survey parties, and notably from Messrs. ,1. B. Marcoii, ( . 

 I). 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.j and Mr. Whitman Cross sent in a collection of the zeolites 

 from 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. II. 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 

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

 Bailey, Audover. Me., a collection of the lepidolite, &c, from the new 

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

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

 quarries near Middletowu, Conn. ; from G. F. Kunz, a very full set of 

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

 St. Petersburg, a number of rare Russian minerals; and from Ward & 

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

 senting various localities, among them a good specimen of Japanese 

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

 dons have not yet been actually received. 



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

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

 received a tine slice of the meteoric iron from Robertson County. Ten- 

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

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

 Mocs and Pultusk tails. The large meteoric iron, weighing 52 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 and description. 



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



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



in preparation for the New Orleans Exposition. The Willcox collection, 



<t. has been arranged and labeled, and L,655 specimens of the 



um collection proper are now on view. The plan <>t' arrangement
