The White Stallion — John Rose Putnam

Tom and Lacey, eager to start a horse ranch, but needing stock, instead make a dangerous pursuit across gold country to rescue a kidnapped baby. On the way Lacey nearly dies from a gunshot wound, but at last they arrive in the great valley of California. The kidnappers are close. Then a magnificent white stallion calls his mares. He would be an ideal sire to start a herd, but can they catch him and still rescue the infant? If his captors see the chase, Tom and Lacey might be killed.
