sistibly drawn to the striking and diversified geological fea- 
tures before him. For he has a view of nearly all the sec- | 
ondary region, extending from New-Haven about 110 miles 
northerly ; and he sees a vast extent of primitive on its 
borders. As he casts his eye over this extensive tract, he 
perceives many of those grand characteristics of the differ- 
ent rock formations, which are not derived from their com- 
diluvian stream. He may be pointed also to the South- 
ampton vein of lead ore in its whole extent; and to the 
localities of the beautiful beryls, sappars, tourmalines, &ce. 
of Haddam and Chesterfield. 
‘This geologist cannot but perceive that the extensive val- 
le , north and west of Ho yoke, must, at some remote pe- 
riod, have been covered by the waters of the Connecticut, 
ere the passage between Holyoke and Tom was worn 
through—And_he will also conclude, that another similar, 
but much larger lake, must have existed in the extensive ba- 
sin south of Holyoke, before the waters of the Connecticut 
had forced a passage through the mountains below Middle- 
town. Hence he will be led to speculate upon the pe- 
riod. when these waters began to subside, and upon the 
ume requisite to wear away such immense masses of rock : 
and ere he is aware, his thoughts will be led back to the 
period, when the cataract of Niagara began its seven mile
