THE BOTANISTS OF PHILADELPHIA. 433 



The Dundas Elm. The finest tree in the City of Phila- 

 delphia, at Broad and Walnut Streets, which is variously 

 estimated from 150 to 400 years of age. It was once a part 

 of the Vauxhall gardens. On September 8, 1819, when a 

 mob, incensed at the failure of an announced balloon 

 ascension, set fire to the garden, the flames spread to the 

 branches of the tree several times, but were promptly 

 extinguished by the firemen. For an illustration of this 

 tree see Forest Leaves, IV, p. 136. 



Bartram Oypress. This tree (see ante, page 05) still 

 standing, although dead, is seven feet in diameter, and was 

 planted about 17(39. (Forest Leaves, V, p. 120, for full-page 

 illustration.) 



The Rodman Buttonwood Tree. Standing at a place 

 called Flushing, in Bucks County, Pennsylvania, on the 

 Newportville Road, about one half-mile from Newportville, 

 and about two miles from Croydon Station, Pennsylvania 

 Railroad. Planted about 1745 by William Rodman. The 

 tree measures twenty -nine feet six inches at a point two feet 

 from the ground, and twenty-eight feet, four inches in cir- 

 cumference at a point six feet from the ground. It appears 

 to be in a perfect state of preservation (Forest Leaves, 

 VI, p. 12).
