great. The exhibit, which was entirely rearranged early in the 
year, has been specially appreciated by teachers of geography and 
nature study, who have brought their classes here in large num- 
bers to study the collections. Among plants of special interest 
that have fruited during the year may be mentioned the banana, 
lemon, kumquat, citron, lime, grape-fruit, fig, pineapple, loquat, 
papaw, besides such others as sugar-cane, ginger, sisal, Manila- 
hemp, tea, coffee, chocolate, Para rubber, camphor, West Indian 
cedar, Eucalyptus, date-palm, cocoanut palm, papyrus, vanilla, 
and numerous others. 
Australian Cycads.—The arrival on February 16 of a collection 
of living plants of Australian cycads, collected especially for our 
Garden, by cooperation with the botanic gardens at Rockhampton, 
Queensland, was noted in the Recorp for July, 1915. Notwith- 
standing the fact that, owing to the war conditions, the plants did 
not reach us until about seven months after they were collected, 
they have practically all done well under the care of the head 
gardener. The species represented are Cycas media, Macrozamia 
spiralis, Macrozamia Moorei, and Bowenia serrulata, with stami- 
nate and carpellate specimens of each. They are not only of 
much scientific interest and value, but will, in time, make very 
beautiful specimens. Unless the new wings of the conservatories 
are completed before next winter, we shall be in danger of losing 
some of the plants on account of not being able to give them a 
proper environment. 
Library 
Growth.—The accompanying report of the librarian records a 
total of 3,804 books and 5,885 pamphlets; of these 771 books and 
2,235 pamphlets were accessioned during the year. Two hun- 
dred and twenty-four current periodicals are now regularly re- 
ceived by gift, purchase or exchange. Special attention is called 
to the valuable gift from the Hoagland Bacteriological Labora- 
tory of 142 volumes of the Comptes Rendus de l Academy des 
Sciences (Paris), and eight volumes of the Journal of the Royal 
Microscopical Society of London. 
The number of readers increases as much as could be expected 
for a purely reference library, largely technical, and confined to
