SECOND ANNUAL REPORT OF THE DIRECTOR. 33 
“3, That Professor Wm. Trelease, of the University of Wisconsin, be invited to 
fill the same; his duties to begin at the commencement of the next academic year, 
September 17. 
“4. That said School of Botany be placed under the special care and direction of 
an Advisory Committee, to consist of five members, of whom two shall be members 
of this Board, and two shall be selected outside of the Board, — the Chancellor of 
the University being a member ex officio.” 
This report was accepted and the resolutions unanimously adopted. 
The record of such action was then submitted to Mr. Shaw and approved 
by him. 
The laboratory cf the School of Botany is temporarily located at 1724 
Washington avenue, and a good working library, containing the usual 
laboratory manuals and periodicals, with memoirs on subjects likely to 
be studied, is kept in the laboratory for reference. This is being con- 
stantly added to, and will be made as complete as possible in any de- 
partment of botany in which advanced students present themselves. 
The herbarium of the school will include as complete a collection as 
can be made of the wild plants of the region about St. Louis. Full sets 
of duplicate specimens are supplied for the use of students of particular 
groups of plants. Advanced students will also have the privilege of 
consulting, under certain restrictions, the excellent herbarium and 
library of the Botanical Garden, including the Engelmann herbarium and 
library, as well as several sets of Fungi exsiccati and the private crypto- 
gamic herbarium and library of the professor. 
Material for laboratory use, and for the illustration of lectures, is 
furnished in abundance by the Garden, which, with its greenhouses and 
arboretum, is open to students of the School of Botany for all necessary 
purposes of study. In case duplicate herbarium specimens which have 
been studied, are desired by members of the class, they may be retained 
if application is made at the beginning of the course, and are charged 
for at cost. Where alcohol and other expensive substances are used in 
quantity, a special charge for material used will be made at the end of 
the course. 
The instrumental equipment of the laboratory includes one microscope 
by Zeiss, with a working series of objectives from A. A. to 1-18 inch 
homogeneous immersion, and accessories for spectroscopic studies and 
work with polarized light; ten microscopes by Leitz, with the objectives 
needed for the best botanical work (including five oil immersion 1-12 
in. lenses, one 1-16 in. oil immersion, and one 1-20 in. oil immersion), 
polariscope, camera lucidas of several patterns, etc.; seventeen dissect- 
ing microscopes, mostly by Bausch and Lomb; and a number of simple 
tripods; sledge and rocking microtomes; a full set of bacteriological 
appliances; together with instruments, pipettes, reagents, and other 
necessaries. Microscopes, dissecting needles, and glassware, are fur- 
nished by the laboratory, members of the class being held responsible 
for breakage or other injury. Razors or other instruments for section- 
ing are not supplied by the laboratory for ordinary work. 
The working year of the School of Botany is divided into three terms;
