The trimming and mounting are what seem most to perplexthe worker who is making his first acquaintance with stereo-scopy. If the negative was taken with a pair of lenses on asingle plate, the prints must be cut apart and transposed be-fore mounting; the right-hand print of the pair being mountedon the left, and the left-hand print on the right. If they aremarked in pencil on the back before cutting no confusion canoccur.
