ing the year. More than ii,ooo new numbers have been marked on 

 specimens. 



In the Department of Botany the following 14 cases have been 

 installed, labeled in full, and placed on exhibition: Of the American 

 Forestry Series: Pride-of -China tree, Oregon Yew; Garry's Oak, Buck- 

 wheat tree; Hercules' club, Oregon Elder; Service tree, Southern Cherry; 

 Oregon Crab-apple, Bitter Cherry; Sitka Willow, Wild Crab-apple; 

 Myrtle Oak, Wild Plum; Devil-wood, Georgia Bark; Striped Maple, 

 Mountain Laurel; Vine Maple, Yaupon. Of the Systematic Series: 

 Two cases displa3H[ng the characteristic products and utilization of Sea- 

 weeds; one case illustrating the economic products of the Soapwort 

 family; and one case devoted to the botany and economics of the 

 Spikenard family. A nimiber of cases have been reinstalled to accom- 

 modate plant reproductions or new and specially interesting specimens. 

 In many instances installed cases have been rearranged to better display 

 their contents. Through the interest and munificence of Mr. Stanley 

 Field, the Section of Plant Reproduction was reestablished, in con- 

 nection with the Department of Botany. Five well-lighted connecting 

 laboratories were constructed in the West Annex of the Musetim 

 building designed to accommodate a Biologist, a Glass-worker, an 

 Artist, an Assembler, and a Caster in wax and plaster. The rooms were 

 finished and equipped with apparatus in February. Dr. Dahlgren, the 

 former Biologist in charge, accepted the Assistant Curatorship of 

 Economic Botany in March, and the Museum succeeded in selecting 

 and organizing the working staff on the lines previously employed in 

 this unique and representative work. The training of the staff, each 

 in his special craft, began about the middle of March and actual opera- 

 tions began the first of April. The end of the year finds the following 

 reproductions completed and installed: The Pine Family: a specially 

 preserved natural branch of Georgia Pine, accompanied by an enlarged
