pleted, and those published or in press, I ask leave to file as a special’ 
plementary report, for general circulation. I should be glad to have your 
er for a separate print of a thousand copies of this report, with illustra- 
ons, to be separately bound in pamphlet form at the expense of the State 
iboratory of Natural History. I will only say now, in general, that the 
melusions already reached, especially in Dr. Kofoid’s department of so- 
iled plankton work, cannot fail to command the close attention and strong’ 
‘terest of scientific men, the world over, engaged in investigations of this class, 
The summer opening of the Station to investigating and other independent 
udents resulted in the acceptance of our invitation by twenty-two persons, 
ve of whom were finally prevented from attending. Our accommodations 
ere limited to fifteen workers additional to the Station force, but as the 
yenteen who arrived did not all present themselves at once, we were able to 
*ovide satisfactorily for them. These seventeen visitants represented the 
ates of Ohio, Michigan, Illinois, Iowa, Nebraska. and Utah. Eight were 
embers of college or university faculties; five were teachers of biology in 
gh schools or academies; two were city school superintendents; and two 
ere college students in advanced courses. The colleges and universities 
presented by them were the Wesleyan University, at Bloomington, IIl.; 
e Nebraska Wesleyan University; Carthage College, at Carthage, IIl.; 
nox College, at Galesburg; Lincoln University, at Lincoln; Eureka College, 
'Eureka; Cornell College, at Mt. Vernon, Ia.; Drake University, at Des 
oines, Ta.; the University of Utah, Salt Lake City; and the University of 
anois. The high schools and academies sending instructors to the Station 
ere University School, Cleveland, O.; Detroit High School, Detroit, Mich.; 
e@ Public High School at Dwight, Ill., and the high schools at Havana, IIl., 
id Marshalltown, Ia. 
They were a competent and energetic group of students; a eredit to the 
ation, and [in some respects an aid rather than a hindrance to ‘our work. 
v0 of them, Professor Kelly, of Cornell College, Iowa, and Mr. Beardslee. 
(University School, Cleveland, Ohio, are preparing papers presenting the 
tentific results of their Station investigations, which they have kindly 
aced at my disposal for publication in the State Laboratory Bulletin as a 
rt of the series of papers growing out of the Station work. Our summer 
‘tants were, I think without exception, pronounced in their appreciation of 
> opportunity offered them, and emphatic in their expressions of surprise 
(the attractiveness of the situation and the richness of the biological field 
‘which the Station is established. Several of them have already filed re- 
ests for admission next year. 
Che success of the ‘‘ Summer [Opening,’’ together with several conversa- 
ns which I have had with teachers of biology, public school superintend- 
%s, and the like, have convinced me that it is incumbent upon us, if in any 
¥ practicable, to extend this offering of an opportunity for midsummer 
rk to public school teachers of biology, and I have taken some preliminary
