Filming of a recreation of Michelson's velocity of light experiments, Mount Wilson. An unidentified actor, dressed in a suit and hat, portrays Michelson, sitting under a tent. Three other unidentified men, two film crew members and another actor dressed in a military uniform, stand nearby. Inside the tent are a table holding a mirror, a chair and a stool. The film crew member seen in the foreground is using a camera light meter above a white tarpaulin on the ground. Trees grow behind the tent.
