mcnt prove as successful in the future as it seems to have 
done in these experiments it should not be difficult for growers 
to receive spray cultures for treating the American blight on 
their trees. We have often remarked in The Fruit-Grower 
that we have come across plantations in which at some former 
time woolly aphis had been an awful plague, but which had 
entirely disappeared without any effort on the part of the 
owner to deal with the pest. It is just possible that some of 
these minute fungi may have increased and multiplied in the 
district until the last of the aphis were gone. The experi¬ 
menter also treated apple trees with mixed cultures of Isaria 
densa. Sporotrichum and Botrytis, and claims to have been 
successful in the experiments. The method adopted was by 
collecting leaves which bore dead insects which had been 
destroyed by the fungus and making cultures of them and 
using the cultures in the way we have described. In August, 
1911, another experiment was carried through on 92 cordon 
apple trees. At the base of each tree a culture of Isaria densa 
was dug in. Spores of Botrytis bassiana was sprayed over 
46 trees, and spores of Sporotrichum globuliferum on the 
remaining 46. The trees were examined on September ist, 
and it was found that the portion of trees which had been 
sprayed with the Botrytis were entirely clear of the aphis, 
while the lower parts of some of the portion sprayed with the 
Sporotrichum showed some of the white wool, seeming to 
point to the fact that Botrytis bassiana was the more powerful 
destructor of the two, although the experimenter thinks that 
' there might have been a larger quantity of aphis at the base 
of the trees sprayed with the Sporotrichum. We think there 
is much of value in the findings of Af. le Aloult, and we trust 
that some of our own economic mycologists will go to work 
along these lines and see if it will not be possible to deal with 
the American blight in this country in the same way. Should 
it be found that the effect of spraying with this infected water 
is as effective as the experiments of the author would indicate, 
then would be the time for compulsion to be exercised, even 
at a national charge, to blot out woolly aphis from the orchard 
of this country.— The Fruit-Grower, Fruiterer, Florist. 
The Gardener's Chronicle published a colored plate of a 
new Anemone Pulsatilla Rosea (“Airs. Van Der Elst”) which 
originated on the Royal Tottenham Nurseries, Dedemsvaart, 
Holland. It is really a first-class hardy perennial of great 
commercial value. Those who are acquainted with the white 
fiower can readily imagine what a charming flower a pink 
variety would be, which is the color of this new variety. It 
is very slow of propagation and the only way to propagate it 
being by seed. A rather small percentage comes true to 
color, but it is increasing and the originators hope in the 
course of a few years will likely get as high as 50 or 60 per cent.

A WARNING TO IMPORTERS 
The National Nurseryman. 
Gentlemen: 
During the present month I have had some correspondence 
with Mr. C. L. Marlatt, Chairman of the Federal Horticul¬ 
tural Board, in reference to the entry of certain prohibited 
Pines from France. Mr. Alarlatt says that there have been 
several lots of prohibited Pines arriving in this country which 
were not covered by permits, and the importation of which is 
prohibited by the quarantine rules and regulations, and he 
asks me to warn the nursery trade generally, through the 
trade papers that such business cannot be permitted by the 
Board. 
He calls attention particularly to a new amendment to 
Regulation 5 as pointed below. This provides, in substance, 
that if it is found that any importer is bringing in 
prohibited articles that permits for further importation will 
be refused such importer, and that he will not be allowed to 
bring in any foreign nursery stock, whether prohibited or not. 
In other words, it puts him on the bad list and prevents him 
from handling imported goods. 
It seems to me to be advisable that this notice should be 
brought to the attention of all of your readers. 
Yours truly, 
Wm. Pitkin, 
Chairman.

PLANT QUARANTINE DECISION NO. 2 
The Federal Horticultural Board recommends that regula¬ 
tion 5 of the rules and regulations for carrying out the plant 
quarantine act, published in Circular No. 41, Revised, Office 
of the Secretary, be amended by the addition of the following: 
Permits for the entry of nursery stock or other plants and 
plant products of any grower or exporter may be refused, and 
existing permits may be canceled, on proof that such grower 
or exporter has knowingly shipped into the United States any

tation of which is forbidden by the Secretary of Agriculture

A REMEDY FOR SNAILS 
John F. Horn, of John F. Horn & Bro. of Allentown, Pa., 
having been troubled by snails throughout his range, upon 
advice of a chemist friend obtained a quantity of the Cam¬ 
phor or moth balls used in preserving Winter clothes from 
moths during the Summer. These balls were placed on the 
soil about 12 in. apart; for the past four months he has been 
untroubled by snails.— Florists’ Exchange. 
The time to spray for Apple Tent Caterpillars, Bud Moths 
and Canker Worms is any time before the blossom buds 
appear, using two pounds of Arsenate of Lead to fifty gal¬ 
lons of water or Lime-Sulphur solution.
