This view shows the succession of the rocks and the amount of displacement, which is 

 slightly more than the height of the man standing on the sunken block at the left : the

Figure 



-View of the Fissure about Forty Feet below the Surface 



The contact of Cleveland and Chagrin shales is shown immediately above the large 

 weathered joint plane in the Chagrin ; the dimensions of this plane are 95 by 14 feet, as 

 far as could be measured ; it is believed that this surface largely influenced the position 

 of the crack. Photograph by Frank Carney.
