AMERICAN 
GAME BIRD 
SHOOTING 
By George Bird Grinnell 
This large and profusely illus¬ 
trated volume covers the whole 
field of upland shooting in Amer¬ 
ica. It deals with the birds fol¬ 
lowed by the upland shooter 
with dog and gun, and gives prac¬ 
tically everything that is known 
about the woodcock, the snipe, all 
the North American quail, grouse 
and wild turkeys. This is its 
scheme: 
Part I—Life histories of upland 
game birds; many portraits. 
Part II—Upland shooting, and 
also guns, loads, dogs, clothing. 
Part III—Shooting of the fu¬ 
ture, ruffed grouse, quail, etc. 
There are life-like colored plates 
of the ruffed grouse and quail, and 
48 other full-page plates, with 
many line cuts in the text. 
The book is really the last word 
on upland shooting, and this is 
what some of the authorities think 
of it: 
“It is, I think, a model of what 
such a book should be—but so sel¬ 
dom is. It is, indeed, much more 
than a treatise on field sports, for 
it furnishes such full and excellent 
life histories of the birds of which 
it treats that it should find a place 
in every library devoted to pure 
ornithology.”—William Brewster, 
Cambridge, Mass. 
“A very complete monograph for 
sportsmen and naturalists . 
with anecdotes, of his own and 
others . . . The book will be 
enjoyed not only by sportsmen, but 
by the general reader .”—Sun New 
York. 
“An important, thoroughly reli¬ 
able and well written book; a work 
that will be read with interest and 
pleasure by sportsmen. The work 
is the first complete one of its 
kind .”—Boston Globe. 
“This volume is especially wel¬ 
come—a treat to every man who 
loves to tramp the uplands with 
dog and gun.”— Inter-Ocean, Chi¬ 
cago. 
This book is a companion vol¬ 
ume to American Duck Shooting, 
and the two cover practically the 
whole subject of field shooting 
with the shotgun in North Amer¬ 
ica. 
Illustrated, cloth. About 575 pages.

(continued from page 43) 
At daybreak we sighted four bears, and 
from a prone position using the battle 
sight on my Springfield (too dark to use 
the peep) I fired five deliberate shots at 
the biggest fellow and scored a perfect 
miss. The point blank range of the battle 
sight is, as you know, 540 yds. On the 
rifle range with the same sight at 500 and 
600 yds. I easily score 44 to 46. Please tell 
me why I scored all misses under the above 
conditions. I held below the bear so I 
could just see under him. We could not 
locate a shot. 
Ans.—You made the error that causes 
probably more misses in shooting up or 
down hill than is caused by all other errors 
combined. You did not hold under 
enough. If the point blank range of the 
battle sight is 540 yds. (this is HORIZON¬ 
TAL), at an angle of 60 degree inclina¬ 
tion it is nearly 1,080 yds. The inclined 
point blank range is always greater than 
the horizontal point blank range, and is 
readily determined as follows: For 30 de¬ 
grees inclination multiply the horizontal p. 
b. r. by 8/7; for 45 degrees multiply the 
h. p. b. r. by 7/10; for 60 degrees multiply 
by 2; for 75 degrees multiply by 4; and for 
90 the p. b. r. is the maximum vertical 
range of the bullet. The inclined p. b. r. 
in your case was about 1,080 yds. and the 
height of the inclined trajectory at 500 
yds. is about 7)4 feet. See pages 76, 77 
and 78, B & D’s Practical Interior Ballis¬ 
tics.) You should have held below the 
bear, then, about 7 feet. 
Would suggest that you use a peep not 
less than 1/10 or 1/12 of an inch in diam¬ 
eter. It is far better to adjust the sight 
for the distance than to make allowances 
in holding. However, in shooting up or 
down hill the sight should be lower than 
for the same horizontal range. The great¬ 
er the angle of inclination, the lower the 
sight should be set. The following rule, 
which is applicable to any rifle, is easily re¬ 
membered :— At an angle of 30 degrees 
the sight should be set for % of the same 
horizontal range, at 45 degrees the sight 
should be set for 7/10 of the game hori¬ 
zontal range, for 60 degrees it should be 
set for )4 the same horizontal range, for 
75 degrees for )4 of the same horizontal 
range, and at 90 degrees the sight should 
be set at zero. If you could have set your 
rear sight, it should have been set for J4 
of 540 yds. or 270 yds. If the first bullet 
could not be located, you should have held 
lower and lower until a bullet was located. 
Another cause for misses in shooting up 
or down hill is the vital zone plane of the 
animal is decreased by its obliquity. 
S. J. H., Colorado Springs, Colo.: 
I know three boys who are interested in 
rifle shooting. Can we four organize a 
rifle club? 
Ans.—It is too bad you cannot find more 
boys who will join with you as boys seem 
to be quite plentiful everywhere and it is
