placed in an exposed position at the base of a tree, not more than

A joint meeting of the Torrey Botanical Club and the Wild 
Flower Preservation Society of America was held at the Mansion, 
May 15, with Mrs. E. G. Britton as hostess. Short talks were 
made by Mr. Sereno Stetson on the relation of the Boy Scout 
movement to wild flower preservation and by Mr. H. M. Denslow 
on the native orchids. The address of the day was delivered by 
Mr. Stewardson Brown, of Philadelphia, on the native wild 
flowers of Pennsylvania, including those of the pine barrens of 
New Jersey, and was illustrated by colored slides taken from 
original photographs by the speaker. 
The monograph of the Cactus Family, upon which Dr. 
Britton has been at work for several years in codperation with 
Dr. J. N. Rose, of the United States National Museum, for 
publication by the Carnegie Institution of Washington, is ap- 
proaching completion. Dr. Rose spent portions of April and 
May at the Garden for this investigation. The work will be 
issued in four quarto volumes, freely illustrated by colored 
plates and by reproductions of photographs and line drawings. 
The first volume, in completed page proofs, was turned in for 
printing in May; the second volume, for which illustrations have 
been made, is all ready for the printer; the third volume is 
nearly completed in manuscript, and much work has been done 
upon the fourth.
