of the Annals of Botany, vols. 1-20, 1887-1909, at $237.50. The 
cost of annual subscription ($7.50) plus approximate cost of 
binding ($1.00-$2.00), a total of $8.50 or $9.50, could be met 
by a gift of $250, placed at interest at four per cent. ‘The total 
amount of the gift that would endow this publication in per- 
petuity is approximately $487.50. 
A library gift made for such a definite purpose would have 
unity, would occur in one place on the shelves, and the donor 
(unless wishing to the contrary) could very properly be desig- 
nated by a special book-plate. In case of suspension of publi- 
cation of any periodical, the sum could be applied otherwise, 
either as the donor might designate, or as the needs of the 
library would best be served in the judgment of the librarian 
and the Director of the Garden. There would always be plenty 
of opportunities to utilize the gift to advantage. 
As shown by the table (p. 94), the total sum required to 
endow all of the publications named would be only $5,170.00. 
It is not intended to imply that the immediate and urgent 
needs of the library are covered by these ten periodicals. The 
table is given merely to indicate, in a concrete manner, how 
such a sum as is named, could immediately be put to good use.
