House & Garden 
An Amazing Value 
This Attractive 
Lincoln Wren House 
$1.00 
Here is an unusually attractive bird house—that 
only wrens can use. It looks like a miniature log 
cabin. It is made of wood, tinted a soft brown col¬ 
or that attracts the wren; and has a substantial, 
weatherproof wood roof. 
The song of the wren is melodious and flutelike— 
its amusing ways make it a favorite with everyone. 
It destroys large numbers of obnoxious insects; it 
never hesitates to attack dogs, cats, swallows, and 
other birds when they near its habitation. But it is 
astonishingly friendly to human beings. 
The Lincoln Wren House can only be inhabited by 
the wren—and it is built to especially attract them. 
In appearance it is the equal of wren houses cost¬ 
ing live to seven dollars. And yet because we build 
in tremendous quantities—and ship knocked-down, 
in a form that any child can quickly put together— 
we are able to sell this attractive bird house for 
only $ 1 . 00 —prepaid. (West of Denver and Cana¬ 
da $ 1 . 25 .) 
Here is a real bird house bargain that you should take advan¬ 
tage of! 
Attract wrens—they will liberally repay any attention you 
give them.

pared by dissolving copper sulphate at 
the rate of one pound to a gallon of 
water. One pound of stone lime (cal¬ 
cium oxide) is then slaked with one 
gallon of water, the water being slowly 
added with constant stirring so that the 
lime is not “drowned”. As soon as a 
paste is formed the rest of the remain¬ 
ing water is added. These two prepara¬ 
tions are kept separated and carefully 
corked. When required one part of the 
copper solution is stirred with 40 parts 
of water. A ..final addition of one part 
of lime is then made. When correctly 
made, the mixture, which must be dark 
blue in color, consists of a solution and 
a precipitation. The latter is insolu¬ 
ble basic copper, the former is calcium 
sulphate. For the more delicate plants 
an excess of lime is advisable; this 
does no harm, and may prevent burn¬ 
ing. In fact it is always best to test 
the mixture, w h i c h 
should always be 
freshly made before 
use, for free copper. 
This can easily be done 
by pouring a few drops 
of the concentrated 
solution of potassium 
ferro cyanide into a 
glass containing the 
mixture and if a red¬ 
dish brown precipitate 
is formed, it is a sign 
that more lime must 
be added. 
Another much fav¬ 
ored and very effective 
fungicide is the lime sulphur solution. 
It is not only practical but also efficient. 
One pound of fresh stone lime is slaked 
with vigorous stirring until one gallon 
of water has been added. Then add 
two pounds of flower of sulphur (or 
finely ground sulphur) and boil the 
mixture for one hour. Strain out the 
lumps and dilute every part with 9 of 
water. This fungicide is best sprayed 
w'hile still warm, and it should only be 
used before the foliage has appeared or 
after it has fallen. In the summer, 
when the tree is in its prime, the mix¬ 
ture should be diluted with 40 parts of 
water. Then it also acts as a contact 
insecticide. 
Contact insecticides, as such, are of 
very diverse origin. They kill the in¬ 
sect by coming in direct external contact 
with the animal. But only those are 
controlled which are more or less tender. 
As these substances are easily available 
and are often of service 
against sucking insects, 
they have received 
much prominence. 
The most common 
are the kerosene emul¬ 
sions, tobacco extracts 
and the above men¬ 
tioned lime sulphur. 
The extract of tobacco, 
which is usually a so¬ 
lution of nicotine sul¬ 
phate, cannot be readily 
prepared at home. But 
the kerosene emulsion 
is practically as effi-
