Modern Spraying 
Science has perfected spraying mater¬ 
ials for effectiveness and economy, just as 
the engineer has created machines to 
lessen labor and save time. 
To kill insect pests and control fungus, 
science has developed ONE spraying ma- 
the last word that science has said 
terial 
to save the farmer time and money 
HEXPo 
DRY POWDERED 
INSECTICIDE & FUNGICIDE 
A scientific, concentrated combination 
of Bordeaux and Arsenate of Lead in 
finely divided, fluffy powdered form. 
Dry powder, to save the farmer freight 
on water; dry powder to save the fuss 
and muss with preliminary paste mixing 
and constant stirring. 
HEXPO can be blown on dry, or put in 
water, stirred a little and sprayed. Either 
method provides a perfect even covering that 
sticks on, kills bugs, worms, etc., and controls 
blight. 
HEXPO dees not harden or deteriorate. 
Being concentrated it goes three times as far, 
and when used with water readily stays in 
suspension. 
Try HEXPO on garden or field crops, and in 
the orchard. Once you try it, you'll accept 
no substitute. 
Comes in handy 1-lb., 5-lb. and 10-lb. red, white and 
black cartons or 25, 50, 100 and 200-lb. drums. 
Ask your dealer for HEXPO or write us for instruc¬ 
tive literature and spraying calendar.

The RURAL NEW 
Notes from a Maryland Garden 
The scientists of the Department of 
Agriculture have sent out a new theory 
on the conditions for plant development. 
They claim that it is not the temperature, 
but. the length of daylight that controls 
blooming and fruiting; “that, entirely 
apart from any effect of burning, it is 
possible for plants to have too much sun¬ 
light : in other words, too many hours 
of daylight, in comparison with the num¬ 
ber of hours of darkness. Too long a 
day, as well as too short a day. will pre¬ 
vent many kinds of plants front ever 
reaching their stage of flowering and 
fruiting.” Intensity of the light has 
more influence than is generally sup¬ 
posed. Plants can be brought into bloom 
in greenhouses at any time of the year 
by darkening the house morning and eve¬ 
ning if the day is too long, or by using 
electric light if the day is too short. 
Violets naturally bloom during the com¬ 
paratively short days of Spring, but if 
light-'proof covers are placed over the 
plants and not removed until the sun is 
half it ii hour high each morning during 
the Summer, the violets can he made to 
bloom in the Summer. Spring flowers 
are Spring flowers, because the length of 
the days makes them such, and the Sum¬ 
mer flowers need a longer day. Then, 
too. tin* dissemination of plants naturally 
by seed is limited by the season of bloom. 
At Washington this means July 1. and 
tln> plant lias time to mature its seed. 
In Northern Maine this would mean 
August 1. and therefore tiie plant does 
not have time to mature its seed before 
frost, and the long day of the North will 
not suffice for its needs. Plants that de¬ 
mand a 15-hour day will not mature at 
the equator, where the days are 12 hours 
long continuously. 
According to this theory, certain plants 
have the power gradually to adapt them¬ 
selves to the length of the days. Indian 
corn, for instance, has gradually adapted 
itself to the varying conditions. The 
plant grows faster in the North, and 
blooms and fruits earlier, and a different 
character of corn is produced. Put bring 
the flint corn of New England into 
Southern Maryland, and it will try in 
vain to at once adapt itself to the new 
daylight conditions, and will at first make 
an inferior crop, hut just as it adapted 
itself to the longer days it will again suit 
itself to the shot ter days southward. Put 
the length of daylight is far from being 
all. for temperature suited to the plant 
will cause it to take a longer time where 
the days are short, bet temperature con¬ 
tinuously suitable to the crop. For in¬ 
stance. the corn grown on the hot coast 
of Mexico, where the Summer days 
are shorter than in New England, de¬ 
mands more days of hot weather than 
New England could possibly give, and if 
seed of this is brought at once far North 
it cannot possibly mature grain, though 
it has more sunlight, because it has not 
the temperature needed. 
Tt is also true of a great many plants 
that they develop to greater perfection 
on the northern limit of their growth 
and seif-perpetuation than farther south. 
On Smith's Island, at the mouth of Cape 
Fear River, in North Carolina, our 
native palm, Saltal Palmetto, reaches a 
development that Florida cannot excel. 
I have cut palm leaves there from the 
forest which measured 5x7 feet v i»!> a 
leaf stalk over six feet long, and on the 
eastern side of the river, at the same 
point. Magnolia grandiflora retches its 
northern limit, and the massive trees 
would cut heavy timber. And yet it may 
be as the Department suggests that the 
length of day makes tb limit, for while 
the forest on Smith's Island is full of 
the palms, there is not a plant to be 
found north of that island except where 
they have been brought front the island 
and planted in the city of Wilmington. 
There they fail to fruit, while on the 
island they make plenty of seed. Put 
Magnolia grandiflora reaches the limit in 
the forests of Pnmswiek County. N. C. 
It grows and fruits and seeds as far 
north as Washington and Paltimore. and 
in my boyhood I knew a tree in Laurel 
Hill Cemetery, Philadelphia, where it was 
protected by a belt of coniferous ever¬ 
green trees. It seems reasonable that the 
length of daylight may have a decided 
effect on plants, hut ten - ’ ■ •Pure. 1 be¬ 
lieve, has a far greater elV - ■.
