sylvania University at Lexington, Ky., for the year 1824,” by W. 
H. Richardson, M. D., President of the Board of Managers, and 
C. S. Rafinesque, Ph.D., Secretary. This rare pamphlet, which is 
not recorded in Dr. Call’s very complete life and writings of 
Rafinesque, is of 24 pages, and is printed alternately in English 
and French. It is essentially an appeal for plants and material for 
the garden, and a list of species that it could furnish to kindred 
institutions. This garden was evidently short-lived, inasmuch as 
in Rafinesque’s ‘‘ Neogenyton,” of the following year, 1825, he re- 
marks, ‘I mean, therefore, to indicate and propose in this small 
essay, many of the numerous new genera of plants detected or 
ascertained, some of which were indicated last year, 1824, in the 
Catalogue of the botanical garden which I have tried in vain to 
establish in Lexington.” 
The principal gardens at present operated and in course of de- 
velopment in the United States are as follows: 
I. The Botanic Garden of Harvard University, at Cambridge, 
Mass., founded in 1805. There are about seven acres of land 
under cultivation, a small greenhouse anda famous herbarium and 
library from which have flowed during the past 40 years volumi- 
nous and invaluable contributions to taxonomy and morphology, 
especially of North American plants. There is also a small mor- 
phologic laboratory. The main laboratories and museums con- 
nected 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. Itis 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 avail- 
able for planting. 
2. The Arnold Arboretum of Harvard University, at Jamaica 
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 horti- 
culture. The trustees wisely determined to devote it to forestry 
and dendrology, and effected cooperative 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 pub- _
