as one of their typical springs at which offerings are deposited. In 

 addition, manuscript will be prepared for publication, labels, etc. 

 For this purpose, the services of H. R. Voth has already been secured, 

 and he is now at work upon his notes, drawings, photographs, etc., as 

 well as engaged in shaping the various figures needed for the altar 

 work. 



In the Department of Botany material for general economic collec- 

 tions having been exhausted by the large installations accomplished last 

 year, there remained no complete case display to accomplish this year. 

 The work upon the installation has, therefore, been that of finish rather 

 than that of enlargement. Specimens in 84 cases, installed previous to 

 1909, have been readjusted to render their appearance uniform with 

 the newer and more satisfactory installations. This required the intro- 

 duction of some modern mounts and labels and repainting with the later 

 and ''flatter" background and mount color. Further material has been 

 added to 7 cases; 3 cases have been completely reinstalled; and 2 

 cases installed with new material. Despite many setbacks, caused by 

 delay of the owner of the modeling shop in putting the same in proper 

 condition for occupancy, satisfactory results have been obtained. A 

 glass blower and a helper were regularly added to the staff. The 

 following reproductions and models have been executed and placed on 

 exhibition: A life size reproduction of a complete Sweet Potato plant 

 showing the tubers; enlarged sectional flowers of the Akee, the Man- 

 grove, the Pomegranate, the Sea Grape, the Sour Sop, the Grape Fruit; 

 the male and female flowers of the Papaw (Carica) and the male flower 

 of the White Birch; a full flowering rachis of the Papaw (Carica) and 

 enlarged portions of the male and female catkins of the White Birch; 

 a branch with leaves and fruits of the Pawpaw (Asimina), ripe and 

 sectional fruits of the same ; a large sectioned fruit of the Papaw (Carica) 

 and a series of five reproductions illustrating the development of the 

 fruits of the Mangrove. In addition to these, complete reproductions 

 of large branches of Akee, Sea Grape, Pomegranate, Sour Sop, Grape 

 Fruit, and Mangrove; a complete summit of a Pawpaw tree and com- 

 plete plants of Aloe and Anthurium are ready for assemblage and 

 finishing and the elements of all the various studies made by Dr. Dahl- 

 gren last year in Jamaica are ready for reproduction. The glass blower 

 has reproduced a large number of complete pieces, such as several 

 natural sized spikes of the minute flowers of the Sea Grape and the Akee, 

 complete clusters of Grape Fruit; Papaw flowers, flowers of the Man- 

 grove, Aloe, and Pomegranate; and many hundreds of piece parts of 

 plants (for instance, to show the necessities of this work, 1,200 fruits
