exclusively to teachers, and consists largely 

 of field work. Dr. C. B. Davenport is Di- 

 rector of the Laboratory, and is assisted at 

 the present time by a corps of twelve in- 

 structors. 



The annual budget of the Biological Lab- 

 oratory is about $3,000. About fifty to sixty 

 students, investigators and teachers are resi- 

 dent during the summer months. The results 

 of investigations are published in various 

 journals. In addition, a series of Cold Spring 

 Harbor Monographs, treating bionomically of 

 particular organisms, has been established, of 

 which six numbers have already appeared 

 and three others are in press.

The Station for 

 Experimental Evo- 

 lution was estab- 

 lished by vote of 

 the Board of 

 Trustees of the 

 Carnegie Institu- 

 tion of Washing- 

 ton , December, 

 1903, by the ap- 

 pointment of Dr. 

 C. B. Davenport, 

 of the University 

 of Chicago, as Di- 

 rector. During 

 1904 the Station 

 came into posses-

 acres of land 

 which it now oc-

STATION FOR EXPERIMENTAL EVO- 

 LUTION (CARNEGIE INSTITUTION 

 OF WASHINGTON). 



THE Station for Experimental Evolution 

 is situated at Cold Spring Harbor, Long 

 Island, thirty-two miles from New York. 

 It is located on ground adjacent to the Bio- 

 logical Laboratory of the Brooklyn Institute 

 of Arts and Sciences and the New York Fish 

 Hatchery. The ground occupied by all of 

 these institutions, about fifteen acres, is held 

 in trust from the late John D. Jones, by the 



gathered together and 

 erected. 



The purpose of this Station is to study e.x- 

 perimentally heredity and variability of organ- 

 isms and the improvement of races by 

 hybridization and selection. All the factors 

 which have played a part in organic evolution 

 come into the general scope of the work of 

 this Station. The land consists of excellent 

 garden tracts of alluvial soil between the 

 mouths of two streams emptying into the har- 

 bor. In the garden are growing pedigreed 

 cultures of mais, oenotheia, sunflowers, pop- 

 pies, clovers, tomatoes, etc. 



North of the garden is an acre of land de- 

 voted to the rearing of pedigreed poultry. A 

 shed here contains the young stock of the 

 present season. A number of brooders to the 

 south are used for the rearing of young chicks. 

 In the southwest corner of the land is the resi- 

 dence of the Director with accompanying 

 grounds. A flowing well driven to a depth 

 of 180 feet supplies the buildings on the place 

 with excellent water. The main laboratory, 

 finished January i, 1905, is 60 feet long by 35 

 feet wide and 2jX stories high. It contains 

 rooms for administration, private rooms for 

 investigators, a library room, a photographic 

 room and several large rooms for rearing ter- 

 restrial and aquatic animals under varying 

 conditions of light, temperature and moisture.
