Barring Suspected Stock.

county, California, wrote an article
recently on this subject for the Citro-
graph. 1t is interesting as showing
the great care which California is
taking to keep out, SO far as possible,
all injurious insects. Also as showing
how careful record they have of
the source of infection of the different
enemies of their fruit industry Is
there anything of the kind in this
state?
The Citrograph says:
AS all we'll posted horticulturists
know, all of Our very numerous bad
fruit tree pests have been shipped into
Our state on nursery stock Of various
kinds.
We, of California, are noted for
being in the front rank in the matter
of inspection and quarantine. And
yet it should be apparent to all, that
something has been awry with our
methods, else we would not today be
taxed with such long list of bad
fruit pests
The white scale, Tcerya Purchasi,'
was introduced into California from
Austria on acacia plants in 1868 by
Mr.. George Gordon, of Menlo Park
From there it spread all over the state,
and cost an immense amount of mo-
ney to fight it prior to the introduce
ton Of it's natural enemy, 'Vedalia
Cardinalis"
The red scale, "Aspidiotus Auranti,"
was first introduced into California on
six lemon trees from Australia, by
Don Mateo Keller, of Los Angeles.
When we contemplate the immense
amount of damage done by this pest
to our citrus groves and the hundreds
of thousands of dollars that have been
spent in fighting it, surely we realize
what great thing it would have been
if those little lemon trees had been
dropped into the ocean or burned or
at least quarantined until the trees
were proven to be perfectly clean.
"Mytilaspis Citricola," the purple
scale, was first introduced into the
United States On some lemons ship
ped into Jacksonville, Florida, from
Bermuda in 1855. This was so long
ago and the damage so great in Flor
ida that it would seem to the average
person that every care would have
been taken to keep it out of our state
It has cost California millions of
dollars to learn some of these lessons
and it would appear that the end was
not yet.
The red spider of the citrus tree,
"Tetranychus Mytilaspidis," was ship
ped into California on trees from
Florida, as were also the rust mite
and the silver mite of the lemon and
the Florida wax scale. We haven't
them all yet, and are we to continue
until we have all these known money
Wasters?
The red spider of the deciduous
tree "Bryobia Praetensis," was first
heard of by us on deciduous orchards
IN, the northern part of Our state
where the earlier method was to fight
them by filling the air through the
orchard on damp and foggy days with
sulphur, through broad cast seeder,
and yet, after reading all this, de-
c1duous nursery trees were shipped
south into our county where the I'M
educated eyes of Our inspectors did
not discover the millions of eggs at
the base of twigs and limbs on the
trees. So, Southern California was set
to fighting the pest.
The "San Jose" scale, Aspidiotus
Pernlclosus, came from Northern
China, and was first introduced into
Santa Clara county by James Lick,
IN 1870. Since that time, it has spread
all over the State of California, and
OF the United States as we'll
A m ong the destructive insects
which SO far are not introduced in
our state, will mention Gypsy
moth (Porthetria Dispar), "White
FlV' (AlerOides Citri\ and "Mevicar,l
