Harris Dickson, Old Reliable in Africa (1918)
“ It was this package which riveted the very soul of Said, a square box nearly the size of a shirt-box and quite heavy. So the Dongalawi stiffened like a pointer dog when Zack sneaked from Colonel Spottiswoode's bedroom with a box which clinked, and whispered of the metal that must be in it. Four black apparitions stalked past—natives, naked and silent—shadows coming out of the shadows, and merging into the shadows again. Zack took no chances; he lay low until the Shilluks were gone, then ventured forth again. A door creaked behind him, and Zack dived back into his hiding place. ”
