The Spyglass was created as a result of an experiment by Malone to trap Dust. Malone created two lenses with a lacquer from plants growing in the mulefa world. By accident, Mary realised that when the lenses were covered with oil from the wheel pod trees and held a certain distance apart, she could see Dust. The mulefa gave Malone a tube of bamboo to which the the lenses were attached, keeping them the perfect distance.
