ii'xo The Trees of Great Britain and Ireland 



trees one near the Pagoda which is divided into two main stems, and measured 85 ft. 

 by 7 ft. 9 in. in 1909 ; the other near the pond is a much more spreading and thicker 

 tree, and now measures about 55 ft. by 1 1 ft. At Arley Castle there is a healthy tree 

 free from branches to about 30 ft. up and measuring 70 ft. by 5 ft. 9 in. At Cobham 

 Park there is a fine tree of the same type 86 ft. by 8 ft. 10 in. At Croome Court, 

 Worcestershire, there is a tree grafted on the common oak, 65 ft. by 6 ft. 5 in. At 

 Nuneham Park, Oxon, another was in 1906, 60 ft. by 8 ft. 3 in. At Barton, Bury 

 St. Edmunds, a slender tree measured in 1908, 64 ft. by 4 ft. 2 in. ; at Ampton 

 Park, Suffolk, another, measured by Henry in 1909, is 40 ft. by 5 ft. 10 in. At 

 Glendurgan, Cornwall, Mr. A. B. Jackson measured a thriving tree, 40 ft. by 4 ft. 

 2 in. in 1908. In the Knaphill Nursery, near Woking, there are two specimens 

 of moderate size. I have also seen specimens at Milford House, near Godalming, 

 and at West Dean Park. 



In Scotland we know of no tree of this species ; but in Ireland, at Fota, there 

 is a thriving specimen, 45 ft. by 5 ft. 4 in. in 1907. (H. J. E.)
