with running water, so that it is possible to carry on observations ex- 
tending over considerable time. 
The work has been broadly planned in the interests of science, 
from which it is believed the interests of fish-culture are in no way to 
be separated. It is intended to determine the fauna and flora both 
qualitatively and quantitatively, to record the food and breeding habits 
of the animals, and to make such other observations as may be possible. 
The party at work in the laboratory consists of six persons, as 
follows : 
Prof. J. E. Reighard, University of Michigan, Director. 
Dr. H. B. Ward, University of Michigan. 
Prof. Frank Smith, Trinity College, Conn. 
Mr. H. S. Jennings, Assistant in Morphology, University of 
Michigan. 
Dr. Robt. H. Walcott, Grand Rapids, Mich. 
Mr. A. J. Pieters, Assistant in Botany, University of Mich. 
Each person devotes his attention to a limited field and it is in- 
tended to place some of the collections in the hands of specialists for 
identification. 
The laboratory will be open during July and August and during 
a part of September. Any scientists interested in this work are assured 
of a cordial welcome at the laboratory and two work places are at the 
disposal of such as may wish to remain a longer or shorter time for the 
purpose of carrying on investigations. In the latter case the director 
should be notified as early as possible of the time of arrival and length 
of stay in order that proper arrangements may be made. Detroit is on 
the Michigan Central Railway, one of the main lines from New York 
to Chicago. New Baltimore is reached by steamer, leaving Detroit 
every afternoon and landing at the laboratory dock. It may also be 
reached from Detroit by the Grand Trunk Railway to New Haven and 
thence four miles by stage. Good accommodations may be had in the 
neighbourhood at reasonable rates. Communications should be addres- 
sed to the undersigned at New Baltimore. J. E. Reighard.
