 Respected Frietid,

 several above 30 feet girt, perfectly straight 40 or 50

 from the trunk on a straight line. Cypress are found 

 from 10 to 12 feet diameter, 40 to 50 feet to the limbs. 



In 1791 a yellow poplar grew on the lands of Charles

M'Kenzie says that in latitude 52° 23' 43'' north, are 

 cedars 24 feet in girt, and that canoes made of them 

 cai'ry from 8 to 50 persons, and that an alder was 7 1-2 

 feet in circumference and 40 feet Vvithout a branch. 



In 1785 about 2 miles from Morgan town Virginia,
