THE GUIDE TO NATURE 
A Huge Leaf. 
The accompanying illustration of the 
leaf of the Paulownia or the princess 
tree must evidently be considered a 
huge leaf. It is thirty inches in diam- 
eter, although the tree from which it 
was taken is only one year old. In the 
southern states, the Paulownia is used 
extensively for shade and for ornamen- 
tal purposes and also for the beauty of 
its flowers. Mr. Robert Sparks Walker 
has an interesting article on the 
subject in “American Forestry,” and 
that magazine has kindly lent us this 
cut. Mr. Walker says that the tree is 
remarkably free from insect pests and 
grows rapidly. The leaves are sensitive 
to the frost, and when the sun rises on 
the first morning after a freeze the 
Paulownia begins to drop its leaves,
