appear without leaving beliiiid them any great addition to knowl- 

 edge. It has been left to Harvard to establish the first garden 

 which is exokisively an arboretum and which^ias the size and the 

 jjromise of permanencj' necessarj' for success in its field- 



"As a museum of living plants the Arboretum occupies in 

 West Koxbury two hundred and twenty acres of rolling hills, 

 narrow valleys and broad meadow. "Natural woods of great 

 beauty and interest cover a part of these acres, and among these 

 woods the collections have been planted in natural groups of 

 genera Avhich are easily reached by grass-covered paths leading" 

 from the drives maintained by the City of Boston. 



"Earl}^ in its history it was found necessary to establish for 

 the Arboretum a library and lierbarium for the determination 

 and arrangement of its collections, and these have grown Avith the 

 geneal development of the department. The herbarium is of 

 special interest. It is the only herbarium devoted to trees and 

 shrubs, and these can therefore be more fulh' represented than 

 in a general herbarium in Avhich less attention is usually paid to 

 trees than to some other group of plants. The herbarium already 

 contains large suites of specimens of North Americn.n trees and 

 shrubs, and probably the best representation of the ligneous flora 

 of Japan. Its Chinese and Siberian collections are important, 

 and it contains perhaps the richest collection of the conifers of 

 the world. 



"It is the plan of the Arboretum to continue and extend its 

 explorations that in time its herbarium may contain a represen- 

 tation of the trees and shrubs of the Avorld. 



"In its short life the Arboretum luis collected and arranged 

 one of the greatest of existing collections of living trees and 

 shrubs." 



My visit to the Arnold Arboretum was one of surprise, in- 

 terest and delight. How I wish it had been possible to give an 

 entire .month studA'ing leisurely all the marvels it contains! 



I am deeply indebted to Mr. Sargent for the privilege of 

 bringing in a motor, covering the hundreds of acres in comfort 

 and without fatigue. Motor vehicles are not permitted inside
