This experiment was to test the real existence of canals on Mars.

“Drawing 6*25 inches based upon one by Professor Schiaparelli made 1890 May 16 {La Planète Meurs, p. 474). In this experiment none of the canals shown by Professor Schiaparelli were inserted, but a number of small irregular markings were inserted at haphazard.”
