We next met our young friends in the second volume, "_The Pony Rider
Boys In Texas_." It was on these south-western grazing plains that
the lads took part in a big cattle drive across the state. This new
taste of cowboy life furnished the boys with more excitement than they
had ever dreamed could be crowded into so few weeks. It proved to be
one long round of joyous life in the saddle, yet it was the sort of
joy that is bound up in hard work. Tad's great work in saving a large
part of the herd will still be fresh in the mind of the reader. How
the lads won the liking of even the roughest cowboys was also
stirringly told.

From Texas, as our readers know, the Pony Riders went north, and their
next doings are interestingly chronicled in "_The Pony Rider Boys In
Montana_." Here the boys had the great experience of going over the
old Custer trail, and here it was that Tad and his companions became
involved in a "war" between the sheep and the cattle men. How Tad and
his chums soon found themselves almost in the position of the grist
between the millstones will be instantly recalled. Tad's adventures
with the Blackfeet Indians formed not the least interesting portion of
the story. It was a rare picture of ranch and Indian life of the
present day that our readers found in the third volume of this series.

Perhaps the strangest experiences, as most of our readers will agree,

wild part of the country the Pony Rider Boys had a medley of
adventures---they met with robbers, were lost in the great mountain
forests, and unexpectedly became involved in an accident in a great
mine. The final discovery of the strange secret of the mountains was
the climax of that wonderful saddle journey.

From the wooded Ozarks to the stifling alkali deserts of Nevada was
a long jump, but the lads made it. All of our readers remember the
rousing description of adventures that were set forth in "_The Pony
Rider Boys In The Alkali_." This trip through the grim desert with
its scanty vegetation and scarcity of water proved to be a journey
that fully demonstrated the enduring qualities of these sturdy young
men. The life, far away from all connection with civilization, was
one of constant privation and well-nigh innumerable perils. The
meeting with the crazed hermit of this wild waste formed one of the
most thrilling incidents. The whole vast alka
