TOM SWIFT AND HIS
ULTRASONIC CYCLOPLANE

by VICTOR APPLETON II

“There's part of Bud's wrecked plane!” Hovering in his new cyclo- plane, the SwiftStorm, in turbulent skies above the wilds of the New Guinea jungle, Tom Swift points to wreckage from his best friend's crashed jet. The area, flanked by twin volcanoes, is as forbidding as the de- serted native huts clustered in sinister shadows.
    Without the revolutionary aircraft that is Tom's latest invention, a rescue attempt would be impossible amid the relentless storms lashing the region. Leading a rescue expedition, Tom is up against  insect swarms, fierce bats, deadly snakes, quick- sand, and furtive shadowers who launch barrages of razor-sharp stone missiles.
    Tormented by crafty enemies, the searchers discover that the young pilot is a captive of unscrupulous criminal partners who have made him the victim of a weapon of evil power. Tom struggles to defeat his de- termined foes, who have discovered an ancient secret in the eerie sur- roundings of a dead city watched over by stone gods!
