True to his promise, they did return the following year, carrying to Athensi a great caravan of supplies for the erection of a completely equipped radio sending and receiving station. These supplies were taken up the Niger by boat and finally across the desert by camel. But after finishing the erection of the station, the three Radio Boys set out on an exploring expedition through the heart of Africa in the interests of a new motion picture producing corporation among the backers of which were both Mr. Temple and Mr. Hampton. And the adventures which befell them upon this 5,000 mile journey through jungle wilds and in coming into contact with savage men and beasts, were numerous and varied. All will be duly chronicled in “The Radio Boys in Darkest Africa.” Until then, let us bid them good-bye. THE END.
