Some Patented Devices for Protecting Trees 
barbed Wire Tree Guard, 
J. A. Perou, of Los Angeles, Cal., has patented a 
device for protecting trees against rabbits and other 
small animals. The invention is especially applicable 
for use in growing eucalyptus-trees which are set out 
in great number for commercial purposes when very

small and need protection until they have attained 
the height of about two feet. 
In the drawings, 3 represents a piece of twisted wire 
provided with barbs 4. The ends of the wire are pre- 
ferably connected together in the manner shown in 
Fig. 2, in which 5 represents a loop or eye formed 
upon one end, and 6 a long pin formed by an exten- 
sion of the other end, which passes through the loop 
and is driven into the ground. For the purpose of hold- 
ing the device securely in place around the tree the pin 
6 is provided on one side and a hook 7 on the other, both 
being embedded in the ground. (Patent No. 782,048). 
To Protect Trees from Insects, 
A device for protecting trees and shrubs from in- 
sects has been invented by Adolph Karlsen of Noers- 
noes, Roeken, near Christiana, Norway. 
Figure i is a view of the apparatus seen in protect- 
ing position around the tree. Fig. 2 is a side elevation 
of the device, a portion of ^ne half being removed. 
Fig. 3 is a cross-sectional view along the line a b in 
Fig. 2, and Fig. 4 is a section in larger scale showing 
in detail a part of Fig. 3. 
The device consists in a sleeve i, the diameter of 
W'hich is a little larger than that of the tree near the 
ground, so that it can be pressed down in the earth, as 
shown in Fig. i. The space between the trunk and 
the sleeve is filled with finely-powdered chalk 2 or 
other suitable material. On the sleeve is on the out- 
side fixed an inclined plate 3, forming an annular chan- 
nel which is filled with any sort of adhesive fluid, in 
which the insects may be drowned or held back. At the 
upper edge of the sleeve is attached a screen 5, wTich 
prevents leaves, sand, rain, etc., from covering the 
channel or spoiling the adhesive fluid. 
By means of the chalk mass 2 insects — such as ants, 
beetles, moths, etc., — are prevented from creeping up 
the trunk inside the sleeve, and outside this latter the 
insects will be held back by the adhesive fluid 4. If 
the ciuestion, however, is to protect larger trees, the 
sleeve has to be manufactured in two parts, (see Figs. 
2, 3, and 4.) each part being provided with a channel 3, 
which is closed at the ends by means of walls 6. (Pat- 
ent No. 784,684). 
c/1 Tatent Insecticide, 
James H. White, of Henderson’s Crossroads, Tenn., 
has patented a composition for the destruction of in- 
sects and bugs of all kinds on all kinds of trees and 
plants. The compound consists in the following in- 
gredients in substantially the proportions stated ; pure 
rainwater, one and one-half gallons ; pure corrosive 
sublimate, two ounces ; carbolic acid, one pound ; acqua- 
ammonia, one pound ; arsenite of copper, three and one- 
half ounces Fowler’s solution of arsenic, one and one- 
half pounds. These ingredients are mixed in the order 
stated — that is to ’say, that corrosive sublimate is first 
mixed with the water, the carbolic acid then added, 
and so on until the entire composition is mixed. 
The composition is to be used at the roots of trees, 
plants, etc., so that it may circulate with the sap and 
give tone and new life to the tree or plant and kill all 
insects thereon. It can also be used in spraying trees 
when reduced to about one-half in strength and a good 
comrcsiticn for spraying is accomplished by the above- 
s^'t-for^:'! i-'~r^di'nt'^ v. ith abort twenty per cent, crude 
petroleum-oil added. It is claimed that this compo- 
sition will not only destroy insects in trees and plants, 
but will also improve the growth and health of the tree. 
(Patent No. 778,391).
