your propeller is in the air out of harm s way. The Aerothrust will take you 
anywhere it’s damp! ^ 
Third, you will get greater speed under all kinds of conditions than with the 
underwater propeller. . . , ^ ^ 1

he should avoid, if possible, streams con- 
taining brown trout and frequent those 
inhabited by our native species ; or, if 
the two varieties are found in the same 
water, he may be especially careful to 
return unharmed all brown trout not yet 
well conditioned. 
1 THINK most fishermen find a certain 
charm in the first day of the open 
season, increasing as the years go by. 
In most states this event occurs not long 
after the advent of spring, when nature 
is in promise rather than in fulfilment. 
Often the last of the wintry weather is 
not yet over, and in upland regions the 
angler must contend with adverse con- 
ditions — rough winds, high water, and 
even snow or hail. Often he fishes in- 
dustriously all day, with never a nibble 
or rise. He is not disappointed, however, 
but finds it enough to wander along by 
the brook he has learned to love as a 
friend, and to be grateful that the close 
season both to life and sport is over and 
that the open season begins on that first 
day. 
TRAP SHOOTING 
GUNS AND LOADS 
{Continued from page 156) 
Different conditions of weather, light 
and background, and the variations in 
the intervals of time betw'een the call of 
“pull” and the appearance of the target, 
are quite enough to worry most shooters 
without continually changing powders 
or loads. 
T he design of shotgun stocks has un- 
dergone probably the most radical 
changes in the manufacture of trap- 
guns. Different styles of mechanism, 
balance, or grip, necessitate small varia- 
tions in measurement; but all of our 
modern trap-euns, or standard guns 
which are frequently used for trapshoot- 
ing, w’hether they be pumps, singles or 
doubles, are provided with heavy, long 
and straight stocks that are designed to 
fit the shooter and to enable him to 
break targets almost as much by point- 
ing as by aiming. They distribute the 
recoil so that a day’s shooting will be 
neither unduly painful nor annoying. 
Modern types of pneumatic or soft rub- 
ber recoil pads, slight changes in the 
pitch and -width of the butt plate and 
the heavy, rounded-combs have all con- 
tributed to this end. 
The exact fit of the stock may seem 
a small detail, but to many it is impor- 
tant. Sometimes a small change in the 
height of the comb or the width or slant 
of the butt plate, or maybe the thickness 
or depth of the grip, will add tremen- 
dously to the comfort and speed with 
which the gun can be used. Conse- 
quently, less time and attention are given 
to the gun and more to delivering the 
charge properly on the bird. The gun 
that feels so comfortable that you don’t 
have to pay any attention to it is usually 
the one that breaks the targets. 
Most of the standard trap-guns are 
made with a drop of 1)4 to 1)4 inches 
at the comb, and 1)4 to 2)4 inches at
