Dr. C. Stuart GaceEr, 
Director of the Laboratories. 
Dear Dr. Gager: The board of scientific directors, in ac- 
cepting your ee have instructed me to express their 
great regret at the necessity for doing so, and to write to you a 
letter expressing their appreciation of your services while occu- 
pying this position. 
In carrying out these instructions, it gives me pleasure to say 
that your services both as an instructor of those who have 
studied under you and as an original investigator have been, 
without exception, highly satisfactory. 
Your personal qualities have endeared you to all the members 
of the garden staff who have been brought into close relations 
with you, and you will carry with you our high personal esteem, 
as well as our official approval. Not the least among our feel- 
ings of regret is that in connection with the loss that the scien- 
tific interests of this city and locality will suffer through your 
removal. At the same time, we heartily congratulate Missouri 
upon its good fortune, and trust that you will continue to feel 
bound to us by mutual interest in your work and by the ties of 
good fellowship. 
Sincerely yours, 
(signed) HH. H. Russy, 
Chairman.
