are half a dozen large Mexican specimens of Cereus giganteus, 
from a foot to eighteen inches in thickness, and from ten to fif- 
teen or more feet in height. A dozen or more enormous plants 
of Agave Americana, from Mexico, have been hollowed out so as 
to show the secretion of juice which when fermented yields a 
favorite drink of the Mexicans. 
In the main building there is little to attract the botanical 
student until he reaches the Mexican exhibit, which contains a 
collection of woods (not yet fully labeled) and a fine collection 
of seeds of economic interest. Some of the West. Indian coun- 
tries have similar collections of more or less value. 
The exhibit made by Jamaica is well worth studying, and is 
full of interesting things. Thus may be mentioned fruits of 
Anona, Persea, Myristica, Psidiwm, Achras, and many others ; 
woods of Guaiacum, Cassia, Hamatoxylon, Crescentia, Cinnamo- 
mum, Rosewood (Dalbergia), Cedar (Cedrella), Satinwood (Chlo- 
roxylon), Lace-bark (Lagetta), Fiddle-wood, Bully-tree, Logwood, 
P 
he varieties of Coffee, Pimento, Cacao or Chocolate are well 
Worthy of the attention of the botanist, as are also the large col- 
lections of fruits and seeds yielding spices an 
collection of meals and starches, vegetable oils, 
¢inal products, and fibres.
