Many a little English Walnut tree has 
gone out of an American nursery to an 
American garden or yard where it looked 
unhappy, stood hesitant despite apparent 
good care, and finally quit for no known 
reason—probably for want of lime. 
Strange to say, this need for lime is 
necessary for the English Walnut trees 
grafted on Black Walnut roots, although 
the Black Walnut tree itself can get along 
without the lime. Furthermore, one ex- 
perimenter reports that before a good 
liming the leafhoppers ate the leaves off 
his English Walnut tree, and after a lim- 
ing the leafhoppers let it alone—a good 
illustration of the oft-claimed point: Give 
a tree all it needs for food and it will 
have far less trouble with pests and will 
be much more resistant to diseases.

The third English Walnut “Must”: No 
late growth. The way to kill an English 
Walnut tree for sure in the latitude of 
Pittsburgh, New York or Maryland is to 
cultivate it thoroughly all summer, give 
it lots of nitrogenous fertilizer like hen 
manure, and keep it in rapid growth until 
October. It will go into winter looking like 
the green bay tree of Scripture and come 
out looking as though it had been in a 
fire. This late growth does not have time 
to harden up and ripen, and so falls an 
easy victim to frost. Therefore the lawn is 
an especially favorable place for the Eng- 
lish Walnut. If you wish to fertilize it 
give it some cyanamid or other quickly 
soluble alkaline nitrate in the early 
spring—middle of March, say, or not later 
than the first of April. Let it make one 
period of growth and stop. If it is in a 
garden, don’t cultivate it after August 
Ist. Let the weeds and grass grow and 
choke it down. Give it plenty of phos- 
phorus and plenty of potash. They harden 
the wood and make nuts. Let the nitrogen 
food come from quickly soluble chemicals. 
Follow these three easy “Musts” and 
plant some grafted English Walnut trees 
and you are likely to be independent of 
the grocer for English Walnuts.

Grafted Black Walnuts 
Everyone knows how good the Amer- 
ican Black Walnut (Juglans nigra) is, 
but it is not generally known that it is 
the best of all nuts for cooking purposes. 
It carries its flavor right through the 
oven; other nuts do not. This gives it a 
market with the makers of nut bread, and
