Personally, I have conducted two public courses : one in the 

 spring on the trees and shrubs of Brooklyn and vicinity, with a 

 registration of 66 people ; and the other in the fall on trees ano 

 shrubs in their winter condition, attended by 26 people. 



The following table shows the attendance and registration at the 

 Garden during 1922 : 



Graduate Study- 

 In connection with the cooperative agreement with New York 

 University, whereby candidates for advanced standing in that insti- 

 tution receive graduate instruction in botany at the Garden, Dr. 

 C. W. Ballard, Associate Professor of Materia Medica at Columbia 

 University, registered with us in October, and under our direction 

 has begun investigations in mycology and in the histology of the 

 drug plants collected in 1921-22 on the Mulford Expedition for 

 the Biological Exploration of the Amazon Basin. 



Exhibitions 



From May 9 to 31 we held an exhibition of batik work in which 

 the designs' employed were suggested by parts of plants, such as 

 cross-sections of stems, ovaries, etc., as well as by the flowers and 

 inflorescences. The pieces were the handiwork of Miss Anna 

 Heyward Taylor, who, so far as we can ascertain, is the first to 

 make use of microscopic plant sections for patterns in this way. 

 The attendance at this exhibit was about 1,000. At the Ninth 

 Annual Garden Exhibit for Brooklyn boys and girls, held in the 

 central rotunda of the Laboratory Building on September 29 and 

 30, the attendance was 560. 



During the year Dr. Gundersen, Associate Curator of Plants, 

 has installed in House No. 2 of the conservatories a permanent 

 exhibit illustrating plant evolution. On the central bench in this 

 house are typical plants arranged in order, to illustrate the probable 

 sequence of plant groups through the ages up to the present time. 

 Appropriate explanations accompany the series. 



The exhibit of Boston fern varieties in House No. 10 has also 

 been enriched by Dr. R. C. Benedict, Resident Investigator, and a 

 genealogical chart has been installed at the entrance, setting forth
