complete life and writings of Rafinesque, is of twenty-four 
pages, and is printed alternately in English and French. It 
is essentially an appeal for plants and material for the gar- 
den, and a list of species that it could furnish to kindred in- 
stitutions. This garden was evidently short-lived, inasmuch 
as in Rafinesque’s ‘*‘ Neogenyton” of the following year, 
1825, he remarks, ‘‘I mean, therefore, to indicate and pro- 
pose, in this small essay, many of the numerous new genera 
of plants detected or ascertained, some of which were indi- 
cated last year, 1824, in the Catalogue of the botanical gar- 
den which I have tried in vain to establish in Lexington.” 
The principal gardens at present operated and in course 
of development in the United States are as follows: 
1. The Botanic Garden of Harvard University, at Cam- 
bridge, Mass., founded in 1805. There are about seven 
acres of land under cultivation, a small greenhouse, and a 
famous herbarium and library, from which have flowed dur- 
ing the past forty years voluminous and invaluable contribu- 
tions to taxonomy and morphology, especially of North 
American plants. There is also a small morphologic labora- 
tory. The main laboratories and museums connected with 
the institution are situated in other of the Harvard buildings, 
a short distance away. The system of garden, libraries, 
museum, laboratories and herbaria operated by Harvard 
College is one of the most complete in existence. It is hard 
to say, indeed, in what respect it is not ideal, except in the 
rather wide distance separating the several elements, and the 
small amount of land available for planting. 
2. The Arnold Arboretum of Harvard University, at Ja- 
maica Plain, Mass., was founded through a bequest of $100,- 
000, made about 1870, by Mr. James Arnold, of Providence, 
R. I., to three trustees, to be used for the improvement of 
agriculture or horticulture. The trustees wisely determined 
to devote it to forestry and dendrology, and effected codp- 
erative agreements with Harvard College and the City of 
Boston, which have now given us the greatest tree museum 
in existence, freely open to the visiting public. The planted
