Small OH Greenhouse Heater 
A small greenhouse of eay 350 square 
feet ground area requires a hot-water 
heater with a fire-pot of about 12 inches 
diameter. This gives ample heat, pro¬ 
vided a good fire can be maintained all 
night, but. with such a small fire-pot it 
is impossible to get reliable results with 
a coal fire. With a large heater there is 
little difficulty in regulating the drafts to 
hold a steady fire all night, but with a 
small heater the fire is apt to burn out 
too rapidly, or go out from lack of suffi¬ 
cient draft. The ideal fuel for a small 
greenhouse is kerosene, but l am unable 
to find any hot-water heater of sufficient 
capacity using this fuel. There are on 
the market “tank w^ater heaters” for do¬ 
mestic hot-water supply, but they are not 
of sufficient capacity, and are usually pro¬ 
vided with a kerosene reservoir of one or 
two gallons capacity only. There are also 
numerous vaporizing burners intended to 
use in a coal-burning heater, but they are 
all unreliable on account of carbon de¬ 
posits choking up the extremely fine noz¬ 
zle used. It seems strange that the 
builders of greenhouses show no interest 
in the matter. The extra cost of kerosene 
over coal would amount to little, and 
would be made up in the lessened labor 
in attendance, provided a satisfactory 
burner and heater could be found. 
Mount Ivisco, N. Y. M. P. s. 
Immediately upon receiving the letter, 
I wrote one of the largest greenhouse 
firms in the country, from whom we pur¬ 
chase our supplies, regarding this matter. 
They wrote me that they did not know of 
any satisfactory heater using oil as fuel 
that, they could recommend for applica¬ 
tion to a hot-water heater for greenhouse 
purposes, but they said they were refer¬ 
ring my letter to one of their representa¬ 
tives who had looked into the matter 
somewhat last Winter, when we were all 
restricted in our fuel supply. This man 
says he has not found anything that looks 
satisfactory, but encloses a circular of 
an advertised burner that he says he ex¬ 
pects to see in operation in the near 
future. 
The small heater that usually would be 
sold for a house 18x20 feet would require 
a lot of attention. The proper thing to 
do would be to install a heater about two 
or three times the size required for this 
size house. The extra cost of the larger 
heater over the one that would do the 
job woulil not be nearly as much as it 
would cost, to equip it with some oil¬ 
burning device, and the cost of the oil 
would be very much more than the cost 
of coal. You can depend upon it that 
were there any good, reliable, economical 
method of using either crude or refined 
oil for the heating of very small green¬ 
houses, the firms constructing such houses 
would not only offer such apparatus for 
sale, but would also recommend their in¬ 
stallation as a factor in the elimination 
of labor incident to caring for the fire and 
the removal of ashes. The fact that they 
do not offer them for sale, and in fact do 
not know where they can be purchased, 
is rather conclusive evidence that the 
method would not be entirely satisfactory 
as at present designed. e. j. w. 
The Bowerberry 
Can you tell me anything about the 
bowerberry? It is claimed to be much 
superior to the Himalaya berry, grape¬ 
vine blackberry or the Mammoth climbing 
blackberry. The seedsman also claims 
that they are the most prolific, sweetest 
and most delicious of the blackberry tribe, 
and bear abundantly when one year old. 
Grows 20 to 40 feet in a season. 
Mays Landing, N. J. E. c. w. 
The “Bowerberry” is not one of the 
Himalaya type, but simply a large-grow¬ 
ing dewberry. The fruit is of the round, 
soft sweet type, very good for home use, 
but not carrying well to market. The 
vine is extremely vigorous and is claimed 
to grow 30 feet a season, and it is said 
to be quite hardy. I have considerable 
doubt as to the adaptability of any dew¬ 
berry to heavy loam soils containing 
plenty of lime. For sandy soils with 
acid subsoils this should be worth try¬ 
ing. though for main crop I would stick 
to the well-tried standard upright growing 
sorts. The Bowerberry is useful to train 
on a fence or any sort of trellis. The 
plants should be set in rows five or six 
feet apart, and nine feet apart in the row. 
and the pruning given be such as will 
keep the plant within limits. A good 
plan is to plant a few along a permanent 
fence and try them before any consider¬ 
able area is planted. After fruiting is 
completed the old wood must all be re¬ 
moved. If the soil is very sandy a mulch 
of marsh hay or other material may aid 
in saving moisture during midsummer.

IT 
THE COMPLETE DOPMANT SPRAY 
Makes a Tree 
Troubles 
Controls Aphis Too 
ALL FORMS of aphis,except the wooly aphis, pass 
**• the winter in the egg stage. These eggs hatch in early 
Spring. And since every aphid produces from 50 to 100 
offspring, it is of the utmost importance to the fruit grower, 
to control the first brood in the Spring as they are hatching. 
This can best be done by spraying with “Scalecide” just 
as the buds show green. 
Bulletin 184 of the Massachusetts Experiment Station 
shows on page 52 that “Scalecide” 1 to 1 5 is 100% effi¬ 
cient in killing aphids while hatching—and with only 
“slight injury” to the foliage when “% inch open,” whereas 
lime sulphur 1 to 8 killed less than 10% of the aphids, 
and lime sulphur 1 to 8 with nicotine sulphate 1 to 800 
added, altho effective, caused “considerable i ljury.” 
“Scalecide” used just as the buds are opening will also do 
effectively all that can be done by any dormant spray for 
apples. And the cost is less than for the combined spray 
of lime sulphur and nicotine sulphate. Besides, “Scalecide” 
goes twice as far, consequently it can be applied in one- 
half the time. 
Scalecide controls scale, leaf roller, bud moth, case bearer, blight 
canker and collar rot, all at this spraying. It is a perfectly soluble od 
(if not, don t use it). It penetrates the diseased bark, destroying tho 
disease without the slightest injury to the delicate plant tissues—in 
fact, even invigorates them.
