34 MISSOURI BOTANICAL GARDEN. 
the first beginning with the College year and ending at the Christmas holi- 
days; the second beginning immediately after New Year’s and ending the 
last of March; and the third beginning about the first of April, and continu- 
ing until the Saturday before commencement. Classes for the study of 
particular groups of plants, and special work for advanced students, are 
planned as the demand for them appears. Whenever it is practicable, a 
class for day or night work, in any branch that can be taught with profit, 
will be formed on the application of six persons. The elementary classes 
are so conducted as to require no previous knowledge of botany; but ad- 
mission to advanced classes depends upon a sufficient familiarity with 
the subjects to render the work profitable. Persons desirous of entering 
any class should present themselves promptly at the opening of the 
course. Correspondence is invited from those wishing special instruc- 
tion. 
Correspondence should be addressed to

St. Lours, Mo. 
In closing this report, I wish to express my grateful ap- 
preciation of the courtesy and cordiality with which I have 
been supported by the Board in every effort made in the 
interest of the Garden; and my thanks for many valuable 
suggestions and much kindly assistance given by the Garden 
Committee of the Board, and for the efficient and earnest 
work performed by my assistants and the gardeners of the 
institution. 
Very respectfully, 
WiLuiaM TRELEASE, 
Director.
