176 LONDON TREES 



planted about the same time as the largest of those 

 on the Heath. 



Mill Hill. The rarer trees here were planted by 

 Peter Collinson when he owned the property, and are 

 of particular interest as their sizes were recorded by 

 Loudon, who visited the place in 1835. The Pencil 

 Cedar (Juniperus virginiana) is a magnificent specimen, 

 52 feet in height, the unusually large trunk girthing 

 7 feet at a yard from the ground. Thriving nicely 

 in rather dampish ground is a wide-spreading Deci- 

 duous Cypress (Taxodium distichwri), 45 feet high, the 

 well-rounded bole girthing, at 3 feet and 5 feet, 8 feet 

 and 7 feet 3 inches respectively. From London's 

 measurements the tree has increased greatly in girth 

 since 1835. One of the finest specimens of the Pin 

 or Swamp Oak (Quercus palustris) in the London area 

 is that at Mill Hill, which is 55 feet high, the branch 

 spread being 60 feet, and the stem girth, at 3 feet and 

 5 feet up, 7 feet 3 inches and 6 feet 4 inches. The old 

 and gnarled Acacia stem girths 12 feet 4 inches at a 

 yard from the ground, but dead branches are appearing 

 towards the top. The Cedars of Lebanon are usually 

 shown as the most interesting of the Mill Hill trees, 

 the largest, which stood near Collinson's house, 

 girthing, at 3 feet and 5 feet, 15 feet 6 inches and 15 feet, 

 the spread of branches extending to 66 feet. This 

 tree has been sadly damaged by the wind, some of 

 the biggest branches having been torn away. It is, 

 however, in good health, and should last for many 

 years to perpetuate the memory of Collinson, who is 

 known to have planted the tree. Two other Cedars 

 are interesting as having been planted by the Duke 

 of Richmond. They stand on each side of a path, 

 18 feet apart, the huge trunks girthing 14 feet 2 inches
