Lastly, no account of the flora of the island would be complete with- 
 oitsome mention being made of the famous willow grove, a group of 
fifty or sixty magnificent trees growing in a slight hollow above the bath- 
ingbeach. These trees are probably a hundred and fifty years old, many 
of them have trunks eighteen or twenty feet in circumference, and 
- tone of them show any signs of decay. Taken as a whole, it is prob- 
ably the finest willow grove in the New England states. 
This too brief and imperfect account may serve to give some idea 
ot the fora of Cushing’s island. A botanist could wish for no better 
place in which to study the flora of the northern New England coast.
