Our new Guide-book, forming a part of the Bulletin, and 
also published separately, is a great improvement on its 
predecessor. Its usefulness is increased through the naming 
of all important locations in the Garden. This edition 
includes the new land recently acquired, and is enriched 
by an excellent map. 
Although the work of exploration, owing to scarcity of 
funds, has not shown the activity of some former years, yet 
some good work has been done in this direction. The 
months of February and March were spent by Dr. and Mrs. 
Britton, accompanied by Mr. Wilson, in the Isle of Pines 
and large and important collections were secured. Through 
the generosity of Mr. Charles Deering, Dr. Small has been 
enabled to make two visits to southern Florida, exploring 
little known regions, and making important discoveries. 
At the present time, Dr. Shafer is at work in Argentina, 
his special mission being to secure representations of the 
cactus flora of that country. In this connection, reference 
should be made to the explorations of Dr. Rose, in Vene- 
zuela, in the interest of the same work. Although this 
expedition was conducted by the Carnegie Institution, its 
direct connection with our monograph on the Cactaceae, 
entitles it to mention in this report. 
Great and increasing difficulty has been experienced in 
finding accommodations for the accessions to the her- 
barium. Some relief was experienced by the building of 
twelve additional cases, but this was temporary and in- 
sufficient. In spite of it, and of the crowding of the cases 
to such an extent as to injure and endanger the safety of 
the specimens, it has been found necessary to bundle up 
and store numbers of specimens which are thus rendered 
inaccessible for study. The necessity for additional her- 
barium space has now become acute and must be met in 
some way during the coming year. Steady increase in 
herbarium material is not merely desirable; it is inevitable. 
When a herbarium has reached such proportions and such 
importance as ours, it becomes a natural magnet for the
