there by the powerful current of that river which sets 

 almost due south. 



That these pebbles were brought from near the pri- 

 mitive range of mountains to the east, is probable from 

 thi* circumstance. I have often, when a boy, gathered 

 the carburet of iron or black lead, in rolled masses, 

 among the stones, on this beach. 



It may be said in reply to these remarks, that they 

 are natural results, and could not otherwise be expect- 

 ed ; that where a river runs any distance through a 

 stony country, and even passes some distance through 

 an alluvial soil, the water worn pebbles will in time, 

 be carried down the stream, and be deposited at or 

 near the river's mouth. 



Let us now see whether this opinion is correct. 

 The Windsor river so called, (an auxiliary stream 

 that falls into the Connecticut river,) is composed of 

 two branches, one of which takes its rise in a primitive 

 range in the county of Litchfield, (Conn.) the other in 

 the same range in Massachusetts. The first of these 

 runs in an easterly direction until it arrives at the foot 

 of the mountain near Farming'ton, (Conn.) where it 

 takes a northerly course, until it joins the second 

 branch called Salmon brook, which comes from the 

 northward ; when suddenly turning at right angles, it 

 passes in one stream, through the mountain : from 

 thence it takes a south easterly direction, and dis- 

 charges itself into the Connecticut river on the west 

 side (as may be seen by the map of Connecticut) about 

 two miles below the mouth of the Scantic river. From
