FINANCE 
People often write Pomona College for my Contributions as if it 
were my botanicai legatee when it bought my herbarium, but it 
has no interest in my library or publications nor control over 
them, nor would it be tolerated if attempted. Since 1923 all ma- 
terial collected by me has been mounted or used as its own, but 
not under any agreement with me, The types of my 1926, 1928, 
1930 and 1931 collections went to the College by agreement be-

nancial interest in my work. With these exceptions I have had 
no official connection. My publications are my own and written 
to state my opinions on modern day botany, in spite of unasked 
adviee of timid people, and at my own expense. I do not adver- 
tise nor sell to dealers, nor ask them to be reviewed because rT 
magazines are in the control of propagandists who cannot be tr..s- 
to be fair or honestly review @ publication which does not fol- 
low their code.
