8 Director's Annual Report. 
Judge C. S. Dole, Mr. Francis Gay and Mr. E. G. K. Deverill. 
The exploration of Oahu has been continued, essentially the same 
regions being covered as given in the last report. 
‘‘Most of the loose and unmounted material has been classified 
and incorporated into the Herbarium. Much trouble has been 
occasioned by small mites; and besides the preliminary fumiga- 
tion which every specimen receives before being placed in the 
cases, the whole herbarium has been fumigated three times, twice 
with carbon disulphide and once with hydrocyanic acid gas, the 
latter method only proving effective. As the two rooms where the 
Herbarium is stored are small and tight, this method can be fol- 
lowed easily and with little danger. 
‘The Herbarium contains specimens of nearly every species so 
far reported from these islands, but contains no series illustrating 
the variations which are so striking on this group, and which are 
of the greatest importance to the modern botanist. Many of our 
specimens lack the exact localities from which they were taken, 
which are now recognized as of the utmost importance. For these 
reasons it would be advisable to increase our collections as rapidly 
as possible. ‘The Herbarium consists of :— 
The Mann & Brigham Herbarium 1864-5 (all groups) 909 
The General Herbarium : — 
Higher Plants.
