24 Field Museum of Natural History — Reports, Vol. V. 



two halls, with cases placed to the best advantage, will afford parking 

 for fifty cases of the Joseph N. Field Melanesian Collections to be in- 

 stalled. Preservation of material, photographing, and rearrangement 

 have necessitated work in one hundred cases of the Department during 

 the year. Hall 48 in the East Annex was originally intended to serve 

 as a gallery of Chinese painting. In view of the new material expected 

 soon from San Francisco, however, this plan has been abandoned, and 

 the hall will be reserved for the reception of the pagodas and other 

 new acqmsitions. 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 series, while 17 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 Series; and 4 to General Dendrology. To the North American 

 Forestry Series monographs of the following trees were added: Red or 

 Pencil Cedar, Moimtain Pine, Pitch Pine, Chestnut Oak, Yellow Locust, 

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

 Hop-Hornbeam, Eraser's Umbrella Tree, Cucumber Tree, Beech, 

 Sourwood, Yellow Poplar, Pennsylvania Cherry, Eraser's Fir, Sweet 

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

 drologic Series 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 Series a case was added dsplaying the 

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

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

 bretimi and Spikenard families; two cases devoted to the derivatives 

 of the Birch family; one to those of the Willow, M)ni;le and Walnut 

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

 fanuly; 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 herbariimi, it became necessary to 

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

 material most frequently consulted might be readily accessible the Eura- 

 sian and African material was removed from the organized herbariimi 

 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 like 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
