man’s head, and consists of several nuts of oblong form, about the 
size of a hen’s egg. The kernels of these nuts are exceedingly hard, 
and resemble ivory so nearly that it can with difficulty be detected 
from the genuine article. Many millions of these nuts are brought 
into the United States and England each year, to be manufactured 
into ivory ornaments. 
Other REitARKABLE Trees and Plants. — Cow Tree [palo de 
vaca). A name given to a number of species of trees of differ¬ 
ent natural orders, the milky juice of which is used instead of 
milk. It is a native of Africa, and a lofty tree of beauty, with 
slender stem and dark glossy leaves, nearly a half yard long. For 
several months in the year not a shower moistens its foliage, and its 
branches appear dead; but the native pierces its trunk, and a copi¬ 
ous stream of sweet, nourishing milk flows from it. At sunrise, 
when it flows most freely, the natives can be seen flitting to and fro 
with calabash bowls, and other rude vessels, to secure the milk; 
what a pretty picture they unconsciously make in the rich morning 
sunlight? This milk is nutritious, and is much used; but if we were 
to analyze it, we should not find the milk of the cow, for it is more 
than one-half wax, and fibrine, with a little sugar, a salt of mag¬ 
nesia and water. 
The Candle-Nut Tree is a native of the South Sea Islands. This 
tree bears a heart-shaped nut about the size of a large walnut. An 
excellent oil is produced from this for food and lighting purposes. 
The inhabitants of the. Society Islands, after baking the nuts 
slightly in an oven, and removing the shell, bore holes through the 
kernels and string them on rushes, then hang them up in their 
rude houses for torches and other purposes. These torches are 
much used in fishing by night, and burn with great brilliancy. 
The Traveler’s Tree [Eavenala) is a native of Madagascar, and 
is a vegetable wonder. When the young tree first appears it bears 
several leaves, but as the tree grows, the lower leaves drop off, and in 
an old tree the lowest leaves are thirty or forty feet from the ground. 
The body of the tree resembles that of the plantain, but sends out 
leaves only on the opposite sides, like an immense open fan. The 
tree usually has from twenty to thirty leaves; the stalk of each leaf 
is six or eight feet long, and the flat parts of the leaf four to six 
feet more. The fruit is not juicy, but is filled with a fine silk fibre 
of most brilliant blue, among which are thirty or forty seeds; the
