6.5 to pH 7.0. This lime requirement 
is not unnatural when one considers 
that virtually all the soils in countries 
having the semiarid climate in which 
this tree originated are somewhat alka- 
line. 
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 de- 
spite 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 Eng- 
lish Walnut trees grafted on Black 
Walnut roots, although the Black Wal- 
nut tree itself can get along without 
the lime. Furthermore, one experi- 
menter reports that before a good lim- 
ing the leafhoppers ate the leaves off 
his English Walnut tree, and after 
Top, Busseron Pecan and Kernel.

liming the leafhoppers let it alone. A 
good illustration of the oft-claimea 
point: Give a tree all it needs for food 
and it will have far less trouble with 
pests and will be much more resistani 
to diseases. 
The third English Walnut “Must”: 
No late growth. The way to kill an 
English Walnut tree for sure in the 
laittude 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 English Walnut. If you 
wish to fertilize it give it some cyana- 
mid or other quickly soluble alkaline 
nitrate in the early spring—middle of 
March, say, or not later than the first 
of April’ Let 10 make one period of 
erowth 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 phosphorus 
and plenty of potash. They harden 
the wood and make nuts. Let the 
nitrogen food come from quickly solu- 
ble chemicals. 
Follow these three easy “Musts” and 
plant some grafted English Walnut 
trees and you are likely to be inde- 
pendent of the grocer for English Wal- 
nuts.

but it is not generally known that it is 
the best of all nuts for cooking pur-
