In writing to Advertisers mention Forest and Strean. 
The tracks in the snow will not van- 
ish until wind or storm or thaw erases 
them. The scent trail, however, is not 
nearly so permanent. It will last but a 
few hours. Tall stories of remarkable 
hound dogs to the contrary, a game 
trail thirty hours old is beyond the 
power of any dog. 
It is entirely possible to examine and 
analyze the unseen. Do we not actually 
measure electricity? So we really do 
know something about this invisible 
animal scent. 
The odor of fox clings to every hair 
of the fleeing animal—it is really just 
as much a part of the fox as its hair. 
You might wash and scrub for a week 
but you could never remove this foxy 
smell. Every bit of skin, every hair, is 
continually exuding this odor. Every 
animal skin, including the human body, 
has this same scent-giving trait. And 
some animals are provided with special 
scent glands to make them even more 
conspicuous. 
So the running fox leaves behind him 
the footprints in the snow which 
the dog, having eyes as well as nose, 
can see and could follow if he chose. 
But this method is too slow and too un- 
certain. It does very well for slow mov- 
ing man, in good tracking snow, but 
where would you be when there wasn’t 
any snow? Behind the fox is also the 
much easier followed, slowly expanding, 
cylinder of scent laden air, larger in the 
beginning than the fox’s small red body 
and now many feet in diameter. This 
air cylinder of invisible fox scent be- 
gins where the fox left its bed and ex- 
tends over the hills and through the 
woods to the running animal’s rapidly 
moving body. It grows just as fast as 
the fox moves, stops when he stops, 
stays with him close as his shadow. 
No wind is blowing, so there the scent 
hangs in the air, resting lightly on the 
ground, marking a plain pathway di- 
rectly to the fox, no matter where he 
goes, which is just as “visible” to the 
pursuing hound’s nose as the footprints 
in the snow are to the hunter’s eyes. 
And down this “tunnel” of scent the 
fox-hound races, head high, calling to 
the hunter in loud exultant voice. 
OW the fox reaches the top of a 
high h‘ll where a bit of wind is 
blowing. Obviously the scent form in 
the air is distorted by the moving air, 
actually blown away. Under similar 
circumstances I have seen a hound run- 
ning down the scent “tunnel” of a deer 
which wasn’t within a hundred feet of 
where the deer had actually passed, be- 
cause the wind was blowing the scent 
slowly along over the ground. 
With the first bit of wind the cylin- 
drical shape of the scent “tunnel” is 
lost and it becomes fan-shaped, with 
the point of the fan close to the ground 
| where the fox’s feet touched, because 
these footprints are still giving off 
scent and will continue to do so, in ever 
diminishing quantities, for hours to 
come. From these tracks the scent is’ 
blown in leeward in a moving, waving, 
uncertain stream of scent, which is ever 
widening and diffusing until it soon be- 
comes too faint for any animal nose to 
detect it. 
As the wind blows away the scent, 
and the tracks become older, the pur- 
suing dog no longer races along the 
scent path with head high. His nose 
begins to drop closer and closer to 
earth, searching for the stronger scent 
clinging to the damp snow in the fox 
tracks. The holes punched in the snow 
by the fox’s feet are still full of scent, 
which keeps boiling up into the sur 
rounding air. When the scent is en- 
tirely restricted to the footprints the 
dog has to slow up and carefully nose 
out the way until air conditions are 
more favorable. 






































EMEMBER that back of the dog, 
as he chases the fox, is another an 
similar “tunnel” of dog scent, now 
mixed with fox scent, but easily dis- 
tinguishable by any animal, and down 
which a pack of hungry wolves could 
easily follow the dog. Every moving 
animal, including man, leaves behind 
just such a scent trail wherever it goes. 
Just as animals know that if they 
stand out in the open they can be seen, 
or if they make a lot of noise they can 
be heard, so do they fully understand 
this matter of scent. Moving game 
travels into the wind. Deer, foxes and 
rabbits have many tricks to confuse 
pursuers. ' 
The nature of this body scent is some 
thing for scientists to write about. We 
really don’t know much about it. A 
bit of musk, from the scent glands of 
the tiny musk deer of Asia, will give 
off a continuous stream of scent for 
years and years without any percep 
able difference in size or weight. It is 
these tiny atoms of matter which beat 
upon the sensitive nerve ends of our) 
nostrils, that are registered in the brain | 
as scent. 
@us noses are certainly not what 
they used to be. Even our eyes) 
are but feeble things compared with the | 
eyes of an eagle or a plains antelop =f 
Our ears, as we know, are limited to a 
certain restricted scale of sound and 
there is a whole world of sound too 
low and too high for our ears. { 
And it is thought, with much sub-_ 
stantiating evidence, that certain in- 
sects, notably moths, have a sense of 
smell even more highly developed tha 
It will identify you.
