The fifth volume of the Standard Cyclopedia of Hor¬ 
ticulture by L. H. Bailey has been distributed covering 
letters P—R. 
With each succeeding volume one is more impressed 
with the immensity and thoroughness of the work. 
Opening the book at random the subject “Persimmon” 
will illustrate its scope. It not only tells you all about 
the wild native fruit, but gives a list of the improved var¬ 
ieties now being cultivated, and how to propagate them. 
The less known J apanese Persimmons are also compre¬ 
hensively dealt with, a full page of line drawings illus¬ 
trating the different varieties. 
The text also dealing with their market value, hard¬ 
iness, etc., in fact, all the necessary information one is 
likely to need if they were going into the business of 
growing them. 
This article alone, to an interested person is worth the 
price of the entire set of volumes. 
Without question a set of this invaluable work should 
be handy for reference in the office of every nurseryman 
and horticulturist and it should be the prime object of 
every young student to possess a set. It will give him 
ready access to the best horticultural information obtain¬ 
able. 
It is published by the MacMillan Company, 66 Fifth 
avenue, New York. Price $6.00 per volume. 
HOW TO CONTROL THE GRAPE LEAF-FOLDER 
The grape leaf-folder, a small “worm” which folds 
portions of grapevines over it, feeding within this shel¬ 
ter, can be controlled satisfactorily, say entomologists of 
the U. S. Department of Agriculture. The pest is the 
larva of a brown moth. Spraying regularly with arsen¬ 
ical solutions, crushing the larvae by hand in the folded 
leaves during the growing season, and burning all dead 
leaves and trash under the vines in the fall, are the con¬ 
trol measures recommended in a recent publication, De¬ 
partment Bulletin No. 419. by J. F. Strauss. 
A satisfactory arsenical for use in combating the leaf- 
folder is arsenate of lead. This may well be applied in 
a fungicide such as Bordeaux mixture, a single applica¬ 
tion then serving as a treatment for disease and other in¬ 
sect pests. The first application should be made shortly 
after the blossoms fall in the spring. This should dis¬ 
pose of the first brood of grape leaf-folders effectually, 
but, if the pest appears later, the application should be 
repeated. It is advisable to burn the dead leaves in 
autumn, because the insect winters over in its pupal 
stage in the ground litter. Several parasitic enemies of 
the insect have been discovered. They are particularly 
valuable in destroying the pupae. 
The grape leaf-folder is distributed throughout the 
United States, but is most troublesome in the Central and 
Middle Atlantic States. It attacks both wild and cul¬ 
tivated grapes and a few other plants, including the Vir¬ 
ginia creeper. It is injurious to the fruit of the grape¬ 
vines attacked, since it destroys the foliage at a time when 
this is most needed to ripen the fruit properly. Often 
as much as four-fifths of the foliage is destroyed. 
The moth, of which the grape leaf-folder is the larva, 
has dark brown, opalescent wings, bordered with white. 
The body is black, crossed by two white bands in the fe¬ 
male and one in the male. The egg is very minute. The 
fully grown larva is about an inch long, yellow-green on 
the sides and somewhat darker above with scattered, fine, 
yellow hairs on each segment. 
The larva begins folding the leaf when about two 
weeks old. This is done by spinning fine silken threads 
across a portion of the leaf near the edge, each strand be¬ 
ing shorter than that preceding. This procedure grad¬ 
ually draws the leaf over. The folded portion of the 
leaf is then made fast to the leaf proper by shorter strands 
of silk. Within this shelter the larva feeds, skeletoniz¬ 
ing the portions of the leaf within reach. 
Mr. J. H. H. Boyd. McMinnville, Tenn., has pur¬ 
chased the growing stock and business of the Hill’s Creek 
Nursery Company and is very busy with a force of 
helpers arranging for his fall shipments. 
Mr. Boyd handles a large line of ornamental and forest 
trees and seedlings, both collected and nursery grown.
