Mammy Moon, herself, or fiery-eyed Mars, perhaps.

"I don't believe that Dad has slept for two nights now, thinking about
its safe return," said Pemrose to Una, as in the starless,
breeze-tickled night the two crouched together upon the mountain-top.

"Well! that little firefly, the tiny electric lamp--the 'wee bit
battery', as Andrew calls it--will guide us to finding it when it drifts
down," panted the other girl, excitement fixing that little peculiar
stand, like a golden lamp, in her dark eye.

"Yes, but--" perhaps her dream in the bungalow of Ta-te, the tempest,
was affecting Pemrose--"but suppose, oh! suppose, that the wind--there

To Pem it was as she had dreamed it would be, away back in her father's
laboratory, before the February train wreck.

Hands seemed reaching out to her from everywhere,--she the satellite
reflecting her father's light.

From the four quarters of the habitable earth eyes seemed trained upon
