and burn until winter puts their fires out, ex- 
cept the embers of their fruit. 
The poison-sumac (R. vernix) is the earliest 
to turn in the fall, and the most brilliant of all, 
but, like its brother poison-ivy (R. radicans) 
its great beauty should not save it from ex- 
termination. ‘They are both a menace to 
people with sensitive skins, and have no place 
except in the wilds. 
The fragrant sumac (R, aromatica) is a 
sprawling shrub which does well under trees. 
Its leaves are downy and aromatic when 
crushed. 
The sumacs do well on dry rocky hillsides, 
and when a house is built in such a situation 
nothing could be more suitable to cover its 
hough stone foundations. ‘They are easy to 
grow and can be transplanted from the fields 
with good success. 
INSECT ENEMIES OF THE 
GARDENER 
VERY thing has its price, and the price 
of a successful flower garden is eternal 
vigilance. From the first appearance of 
any green leaf or blade above ground there 
is a simultaneous appearance of something to 
destroy it; indeed, most of the worms and 
caterpillars time their appearance by the 
burgeoning of the trees and plants. Secure 
the chrysalid of any of the large moths—that 
of the tomato worm—Protoparce carolina, for 
instance, and keep it in a warm room, it will 
defer its appearance from the chrysalid until 
the time that the tomato leaves are green, quite 
as well as though left in the open ground, so, 
too, the large prometheus moths which lay their 
eggs on the woodbine and do not emerge from 
their case until the leaves appear on the vine. 
The first worm to cause actual trouble in 
the garden is the cutworm, and these do much 
damage to young plants, often making it neces- 
sary to make several plantings before a perma- 
nent output is secured. Usually it will be 
sufficient—if the planting is not so large as to 
make the labor too great—to enclose each 
plant with a small tin can which has had the 
bottom melted away. Many gardeners make 
a practice of gathering up during the winter 
all the old tin cans available. In the spring 
a fire is kindled out of doors and the cans 
thrown upon it until they are melted and the 
bottoms drop off. They are then ready to be 
used and are pressed into the soil around the 
plant, pressing them down an inch or two. 
But in using this form of protection it is im- 
portant to see that no worms are enclosed 
within the barrier. Other gardeners have suc- 
cess bating the worms with meal wet with 
sweetened water in which a small quantity of 
Paris green is placed, or chopped grass or 
clover is used instead, but care must be used 
where any form of poison is employed, as it is 
quite as apt to exterminate any chickens which 
gain access to it as the worms it is intended 
for. Fortunately, not much harm is done by 
this pest after the last of May, but another 
serious pest of similar habits makes its appear- 
ance soon after the disappearance of the cut- 
worm; this is the small brown or pink worm 
or grub, known variously as the cosmos borer, 
the dahlia or aster worm, etc. ‘This little pest 
enters the stalk of these plants close to, or just 
under, the surface of the ground and proceeds 
to eat his way upward, and its presence is sus- 
pected only when attention is attracted to the 
plants by their blackened and withered appear- 
ance. It is not altogether a hopeless pest, how- 
ever, as both preventative and remedial meas- 
ures may be taken. The prevention consists in 
soaking the ground about the plants for a 
depth of three or four inches with a week solu- 
tion of Paris green, applied every week, from 
the time the plants are a foot high until fully
