10 THE NATURALIST IN BERMUDA. 
The North Rock, which lies some nine miles to the north- 
ward of the islands, is obviously the last remnant of a 
former island; the tops of the pinnacles are stratified. In 
old French charts, the North Rock is called “Les Petites 
Bermudas.” According to Williams, in his History of the 
Bermudas, this rock, or rather rocks,—for there are four 
needle-like structures,—stand ten feet above high water, 
and vary from four to about eight feet in diameter, and, 
when struck by the hand, they ring, being sonorous in a 
remarkable degree.
