Greenhouse and Garden.

Greenhouse and Garden.
Every one who can afford them should
have a few Allamandas. They succeed in
the open air in parts of California, but must
be ranked as greenhouse or stove plants as
rule. There is no handsomer climber. Pot
culture does not suit them best Plant in
free soil and train on pillars or rafters. The
leaves are dark emerald; the flowers rich
golden hue. A warm, moist atmosphere and
plenty OF water are required to success. The
roots extend long distance in rich, light
soil. If border can be had in which to
plant them, specimens can be grown in pots
by rigid system of pinching back. Begin
with well-rooted cutting; place it in a
four-inch pot, and train it to single stem
for a height of twelve inches, then cut it
back to six inches, SO as to form laterals
Let the young wood ripen..well as the autumn
advances. Give but little water in winter
Re-pot when needed, and when in 12-inch
pots train the shoots to a suitable framework
The mealy bug is the worst insect enemy.
Use hair pencil and strong alcohol touching
the spots.
A lovely plant for pot culture in houses,
and also well adapted to garden culture is
the Freesia Refracta The flowers are hand
the plant is graceful
The jasnines are favorites with all who
know them. The large and free-blooming
species should be in even the smallest gar
dens.
The hast novelty in this line is the double
with smooth-edged petals, not as usually,
crimped and somewhat irregular It blooms
all summer and autumn.
Camellias may now be layered and will
root in from three to six months. Some per-
sons will not venture to plant camellias in
the open air, and yet many choice and flor
ferrous specimens are thriving in the imme-
diate vicinity of this city. Plant in a shell
tered location, partially shrouded from the
midday sun. Camellias thrive under fiat
lattice roof. Water them with water in
which guano and little pulverized charcoal
have been dissolved.
AS far as pot plants are concerned, it is
time to be taking steps to increase them.
These autumn days before the rains begin,
and while the atmosphere is yet warm, cause
the slips and the cuttings to root well in leaf
mold and sand.
Cinnerarias and other plants required for
early spring decoration need attention at this
season and must be kept in good state of
growth. Fumigate them occasionally to kill
the green fly, whether or not they are Oh
served. Weedy cinnerarias give little pleas
ure; only the best seed should be sOWn. Gen
erous culture does the rest
Gardeners seldom appreciate the value of
saWdust 1t can be used for roofing cuttings
in, and possesses high qualities in that re-
gard. Mixed, however, with an equal guam
tity Of silver sand, there is nothing better for
he propagating bench. When i'll autumn,
plants are removed to the open border,
handful of sawdust about the stem acts as a
mulch; it also keeps the slugs away.
The Speed Of Thought.
Helmholtz showed that wave of thought |
would require about minute to traverse a
nile Of nerve, and Hirsch found that touch
IN the face was recognized by the brain
md responded to by manual signal in the
seventh of second He also found that the
speed of sense differed for different organs,
5he sense Of hearing being responded to in
sixth of a second; while that of sight re-
iuired only one-fifth second to be telt and
,ignaled. In all these cases the distance
5raversed was about the same so the infer
ence is that images travel more slowly than
sound or touch. 1t still remained, however

Dy the action of the brain Pro. Donders, by
very delicate apparatus, demonstrated this
@ be about seventy y-fve-thousandths of a
second. Of the whole interval, forty-thors-
,ndths are occupied in the simple act of rec
ignition, and thirty fve-thousandths in the
tct of willing response When two irri-
ants were caused to operate ON the same
ense, one-twenty-fifth ola second was re-
,uiraI for the parSOn f0 rpp0UnjZa which was

equired to determine the priority in the

rouths the mental operations are somewhat
quicker than in the adult, the average of
many experiments proved that a simple
hought occupies one-tortieth of second.
