two halls, with cmm placed to the best advantaf^c, will afford parking 

 for fifty cmaeso( the Joaeph N. Field Nfclancsian Collections to be in- 

 stalled. Preservation of material, photof^raphing, and rcarrangonent 

 have neoenitated work in one hundrtxl ca.<;c.s of the Department during 

 the >*ear. Halt 48 in the East Annex was originally intended to serve 

 as a gallery of Chinese painting. In \'icw of the new material expected 

 soon from San Frandsco, however, this plan has been abandooed, and 

 the hall will \ic reserved for the reception of the pagodas and other 

 new acquisitions. The former plaster-room has been divided by a 

 partition-wall into two rooms. 



The Department of Botany has installed 39 new case-units in the 

 public exhibition scries, while 1 7 others have been reinstalled and aug- 

 mented with new and interesting material. Of these cases 15 were 

 added to the Systematic Economic Series; 37 to the North American 

 Forestry Scries; and 4 to General Dendrology. To the North American 

 Forestry Scries nv hs of the following trees were added: Red or 



Pencil Cedar, Moui.i.un i'ine. Pitch Pine, Chestnut Oak, Yellow Locust, 

 Honey Locust, Cork Elm, Red Spruce, Rod Ash, Butternut, Chestnut, 

 Hop-Hombcam, Eraser's Umbrella Tree, Cuoimlxr Tree, Beech, 

 Sour^-ood, Yellow Poplar, Penns>-lvania Cherr>', Eraser's Fir, Sweet 

 Buckeye, Black Willow, Sweet Birch and Yellow Birch. To the Den- 

 drologic Scries was added a display, in four cases, of the woods of the 

 Hawaiian Islands, representing, with fair sized specimens, the trees 

 of the islands as described in the new work of Mr. Joseph F. Rock. 

 To the Systematic Economic Scries a case was added dspla>'ing the 

 fruits, gums, and tan and dye barks belonging to the Combrctum and 

 Mangrove families; one with similar products derived from the Com- 

 brctum and Spikenard families; two cases devoted to the derivatives 

 of the Birch family; one to those of the Willow, M>Ttle and Walnut 

 famiUes; two to the Walnut family alone; one additional to the Oak 

 family; one to the Sapodilla family and one each to the Spurge and the 

 Daisy families. On account of lack of cases and cramped quarters in 

 the rooms devoted to the working herbarium, it became necessary to 

 entirely reorganize the collections during the year. In order that the 

 material most frequently consxiltcd might be readily accessible the Eura- 

 sian and African material was removed from the organized herbarium 

 and placed in a series of metal storage cans racked in the mounting room 

 on the first gallery; and the West Indian, Central and South American 

 specimens rearranged in Uke storage cans racked above the regular 

 herbarium cases. This divides, temporarily, the organized reference 

 collection into three parts. In all three the plants are fully arranged in 

 the order of modem classification. While not so conveniently referable
