 those heights the willows do not at present grow, and no species of willow is now found growing 

 near them. Those roots are of equal size of any that now grow in the ravines many hundred feet 

 feet below. I may add that I have heard visitors to those places make the assertion that those 

 roots are the roots of oaks. T.)
