8 Director's Annual Report. 



Judge C. S. Dole, Mr. Francis Gay and Mr. K. <'.. K. Deverill. 

 The exploration of < >ahu 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 Keen 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 uow 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 1 864- s all groups 909
