Invest In a 
McCormick-Deering Tractor 
for Plowing and Belt Work 
The remarkable new warranty covering 
the crankshaft and the crankshaft ball bear¬

well prove the deciding factor in your own 
investment. The ironclad agreement, printed 
below, provides you with a lasting security 
covering these important parts of the tractor. 
It is evidence of quality in the entire tractor. 
It is an indicator of practical design, accu¬ 
rate assembly, generous 
size of parts, and long life. 
Do your plowing speed¬ 
ily and well with a Mc¬ 
Cormick-Deering and fit 
your tractor to all kinds 
of belt work. McCormick- 
Deering Tractors are de¬ 
signed to handle belt jobs 
as you want them handled.

Nature Notes 
An Equine What-ls-lt? 
The New l T ork Times published on 
December 2, the enclosed half moose, 
half horse picture. Will you comment 
on this biological impossibility of such an 
animal? It is undoubtedly a freak mule. 
New York. THORNTON chard. 
The picture shows the neck and head of 
a curious looking animal with a thin 
long neck and a very heavy upper lip. It 
looks like a mule with the neck of a 
donkey and a malformed head. The di¬ 
rector of the Biological Survey makes 
this comment: 
It is scarcely necessary to say that we 
do not believe it possible that the horse 
and the moose can hybridize. As you 
probably know, the horse and the moose 
belong to different suborders of the great 
class Ungulata, the former being refer- 
able to the suborder Perissodactyla, and 
the latter belonging to the suborder Ar- 
tiodactyla. These very distinct types of 
mammals have been separate since very 
early geological times, and are so distinct 
that they manifestly cannot interbreed.

The Rat Pest 
Since the recent article on rats and 
their destruction of grain and other farm 
crops, we have had many letters from 
our readers. The rat curse is very wide, 
and there can be no question about the 
loss from that pest. We have letters 
from people who find that a smart little 
dog. a fox terrier or one of the other regu¬ 
lar ratting dogs, will prove superior to a 
cat. We have seen one of these little 
dogs at work in a barn, and he certainly 
did a remarkable job at killing vermin. 
We have many reports from cat owners, 
but it appears that cats vary greatly in 
their inclination or ability to fight rats. 
Some of them are willing to tackle a rat 
of any size, but there are others who ac¬ 
tually seem to be afraid of rats, aud they 
confine their work almost entirely to kill¬ 
ing mice. Rat-traps are largely used, but 
no one seems to have actually cleared out 
the pest by the ordinary use of traps. A 
number of our correspondents speak of 
using some of the rat virus so freely of¬ 
fered for sale, and the reports vary con¬ 
siderably. In some cases it really seems 
to have cleaned out the pest. The rats 
disappear suddenly, but after a time an¬ 
other brood comes in, as ravenous as be¬ 
fore. In other eases the virus does uot 
seem to be of any particular value, and 
the conclusion is that some families or 
strains of rats are immune to the disease 
conveyed in this virus, so that it has no 
particular effect upon them. 
Lime-Sulphur to Repel Rabbits 
Some of our readers tell us of success¬ 
ful experience iu keeping rabbits away 
from fruit trees in Winter by painting 
the lower trunk of the tree with a strong 
solution of lime and sulphur, to which a 
small quantity of Paris green lias' been 
mixed. They say they take the standard 
home mixture of lime-sulphur and mix it 
with water about one to five or six, then 
paint it on the tree. Do you think it 
would be of any particular value in kill¬ 
ing borers or keeping off rabbits and 
mice? 
I have had no experience iu using 
the above mentioned mixture for preven¬ 
tion of rabbit injury to trees. For quite 
a good many years we have used only 
mechanical protectors in the form of 
wire screen or building paper. The screen 
is allowed to remain around the trees 
until the period of danger from rabbits 
has passed (until the bodies of the trees 
are three or four inches in diameter). 
Paper protectors are applied each Au¬ 
tumn and taken off in late Spring.

We have in the past applied to the 
lower trunk of fruit trees lime-sulphur 
to which has beeu added a small amount 
of arsenate of lead and enough lime to 
make as thick a solution as could be ap¬ 
plied through a coarse nozzle, for the 
purpose of preventing damage by mice 
and with good results. Omitting the ar¬ 
senate of lead we have used this material 
to prevent attacks of borers. After 
worming the trees, but before replacing 
the earth, we cover the lower trunks 
thoroughly with the above solution. This 
will not kill the borers, but will prevent 
the moth from depositing eggs where this 
material is applied so long as it forms a 
perfect covering. JOHN r. barnes.
