A Book You Will Want to Bead: 
TREE CROPS, A Permanent Agriculture, by J. Russell 
Smith, Sc.I). 
This book explains how our present crops are annuals domes¬ 
ticated by primitive woman in the buried past. Now that the age 
of science has come, it shows how our future crops should be 
grown on trees which are Nature’s real engines of food produc¬ 
tion. The tree is also one of Nature’s soil holders. 
It shows how anyone may begin it now by planting nut trees 
and other little-used cropping trees, and also start growing tree 
food for the beasts—such crops as Honey Locust (grain sub¬ 
stitute), Mulberry, Persimmon, Acorn, and many others. This 
program is a practical one, not just a theoretical set-up. It is based 
on the author’s many years of experience as a practical farmer 
and also on much observation in four continents. 
The book shows how systematic tree breeding may give us the 
nation’s sugar supply from trees, cow feed supply from trees, 
and possibly even our own bread, factory-made from acorns, 
which, by the way, are more nutritious than our present bread 
grains.

ination, or an interest in science, you will like this book. It will be
