nes have been considered assubjects of an unusual nature, a sort of tour de force ofphotography. Yet we have here a range of views speciallysuited for the stereoscope. The pictures which produce thebest results in this instrument are those of a rather darktone, whose technique would be classed as dull or lackingin contrast. But when we examine these pictures in thestereoscope, we notice that much detail in the shadows anddark portions which would not be observed in the singlepicture, stands out with remarkable clearness, and here liesthe special adaptability of stereoscopic photography for theportrayal of night scenes.
