“It Brings The Mark Up Close 
HIS Rifle Telescope, which has a power of about 5 diameters, is designed especially 
for the U. S. Springfield Magazine Rifle, and is equally effective on any sporting 
or repeating rifle of any make. It is set forward of the bolt so that it cannot 
possibly interfere while loading. Its over all length is 20 inches. It is regularly made 
with Pin Sight, although it is put up with cross hairs when so ordered. 
One of the best features of this Telescope is the system of mountings which are easily 
detachable and operate on dovetail blocks screwed firmly to the barrel. The I elescope 
slides in its mountings. It is adjustable for shooting of from 200 to 2,000 yards. 
All Stevens Telescopes are made in our Optical Laboratory of Precision undei the 
direct supervision of a practical optician. 
Our smaller Telescopes, those up to 314 powers, are permanently focused. 
while the high powered Telescopes have a quick slide adjustment, which is also 
p ermanently fixed after the telescope is focused to the eye. 
Write today for our new Telescope Catalog and also our complete catalog of 160 pages with 20Q illustrations.

THE JACK SERIES 
Best Books For Boys 
By GEORGE BIRD GRINNELL 
T HE solution of the parents’ problem of providing for the growing boy reading at once healthy and 
satisfying to his craving for action and adventure. In the Jack Books the longing of the normal boy 
for Western stories is gratified, the interest is absorbed and the mind is unconsciously led to phases 
of life that are ele\ iting and instructive. 
The books are the story of a young New York lad, sent to Stillwater ranch in the Rockies for his health, 
who becomes the companion of a veteran of the frontier. For each of six succeeding years he is led through 
new territory and experiences, accumulating much of the lore of plain and mountain, enriched with tales of 
the old West. 
Ranch life, travel and hunting on the lonely plains, Indian camps, mountain 
climbing, trapping and canoeing are described. There is not a dull page, and the 
author manages to put much of the spirit of the West into his books. Jack is a 
real boy, and the books are stories for live boys—not lectures in disguise.
