and Laboratory Methods. 1281 



The same is also true of the fresh-water ponds ; deep and shallow water and 

 marsh are present with abundant life, the plankton being very rich. 



The most characteristic feature of the marine fauna is its stability. The 

 animals found in the harbor all belong there, and have not been brought 

 in by currents or tides from the open sea ; their characteristics, consequently, 

 have been determined by their relation to the local environment. An excellent 

 opportunity is thus given of studying the conditions which have accompanied the 

 development of a fauna. 



The work of the laboratory is divided into several departments, which, with 

 the instructors who have them in charge, are the following : I. Zoology. In 

 this department, the following courses are given : high-school zoology, by Profes- 

 sors Davenport and S. R. Williams; comparative anatomy, by Professor H. S. 

 Pratt ; invertebrate embryology, by Dr. L. E. Griffin ; entomology, by Dr. A. G. 

 Mayer ; variation and inheritance, by Professor Davenport. II. Botany. In 

 this department the following courses are given : cryptogamic botany, by Dr. D. 

 S. Johnson ; ecology, by Mr. H. N. Whitford ; bacteriology, by Professor N. F. 

 Davis. III. Microscopical Methods, by Mrs C. B. Davenport and Professor 

 W. L. Tower. IV. Nature Study, by Dr. H. A. Kelly. In addition to these 

 courses, evening lectures, both of a technical and of a popular nature, occur 

 several times a week. 



The importance of excursions and collecting trips to give opportunities of 

 studying the fauna and flora in their natural environment is fully appreciated. 

 The laboratory has a launch and small boats with dredging and other collecting 

 apparatus ; a large oyster boat is also occasionally used ; and trips to various 

 parts of the neighboring waters are of daily occurrence. A trip is also made to 

 Fire Island on the south shore of Long Island. Every facility is given for the 

 collection of material for personal use and for the use of the institutions with 

 which the members of the laboratory are connected. 



A valuable feature of the laboratory at Cold Spring Harbor is the quiet and 

 seclusion of the place. Situated a mile from the village of the same name and 

 two miles from the railroad, it is an ideal place for work and rest. The beauti- 

 ful harbor, the fine bathing beach, the excellent roads, the woods and fields, the 

 freshwater ponds, all furnish numerous attractions to the summer visitor outside 

 the work he accomplishes. 



The laboratory building is a modern structure, 72x36 feet, lined inside with 

 Georgia pine, and with excellent ventilation, due to the height of the roof ; it is 

 provided with running water, both fresh and salt, and a complete equipment. A 

 special laboratory for investigators is also now being completed. The lecture 

 hall is a large building lined inside with Georgia pine. The students and other 

 members of the laboratory are housed in three dormitories, one for men, one for 

 women, and one for married couples. The dining hall is run by the laboratory, 

 and board is furnished at cost.
