PLATE 11. 
Figure 1— Banpep Cuay, Woopsvitin, N. H. 
This view is part of that shown in Plate 1. It is shown here for comparison with the slate below. 
Figure 2,— Laminatep State, Newton Crentre, Mass. 
The contortions shown are of uncertain origin. There are no pebbles among the layers. It is 
probable that the result was effected by shearing when the sediments were in an unconsolidated con- 
dition. Whether the force which brought on the shearing was over-riding ice above, or was done during 
later diastrophic movements, it is difficult to say. Tillite does not immediately overlie this slate at 
Newton Centre. ‘
