on a gravelly soil, was examined twenty-one years afterwards, viz, in 1786, and 

 the circumference of some of the best trees taken at 3 ft. above the ground. 

 The small firs had been occasionally drawn for posts and rails ; and also as 

 rafters for cottages ; for which purpose, when peeled of the bark, they will 

 last for seven years.

American Trees introduced in 1769. — In the years 1769, 1770, and 1771, I 

 subscribed to a society then established at Edinburgh, for importing seeds of 

 forest trees from Canada. I received a large quantity of seeds, which came 

 up very well ; and are now growing in my plantations, in a very flourishing 

 condition. The sorts are, the great white spruce, which, I believe, is what 

 the nurserymen call the Newfoundland spruce ; 2d, the American black 

 spruce ; 3d, the balsam fir, which is the most hardy kind, and flourishes in 

 the most exposed situations ; 4th, the great black larix ; 3th, the grey ash ; 

 6th, the red mespilus, which bore fruit three years ago ; 7th, the great white 

 mespilus ; 8th, the great black birch ; 9th, hickory walnuts ; 10th, black wal- 

 nuts. {W. M. Beverley, of Cleveland, Yorkshire, May 23. 1786, in Annals 

 of Agriculture, vol. vi. p. 333.) 



Growth of Trees at Barton, near Bury St. Edmunds. — Amongst the young 

 trees at this place are some which seem worthy of notice. In none of the 

 books of reference do we find the rapid growth of J^bies Douglasw noted as 

 having been at all equal to what has been witnessed here. Sir Henry Bun- 

 bury received from the Horticultural Society a little plant, in a pot, in March, 

 1830 J in the spring of 1831 it was planted out. It is now, as nearly as can 

 be ascertained, 33 ft. high ; the spread of its branches 13 ft., and the girt of 

 its stem, at 1|- ft. from the ground, 30 in. This summer, for the first time, this 

 beautiful tree is bearing cones. Next to the DouglaszV, Pinus Coulteri has 

 been the most rapid in its growth. But a young P. inslgnis is now growing at 

 a prodigious rate. One of the finest trees here is a Magnolia acuminata, which 

 was planted in August, 1823. It is about 331 ft. high, feathering to the ground 

 on every side. The girt of its stem, at 1 ft., is 28 in.j at 4 ft., 24 in. ; at 5^ ft., 

 23 in. A Magnoka auriculata, planted in Nov. 1823, is about 24i ft. high. 

 Some persons in the neighbourhood complain that their Levant oaks (grown 

 in a sandy soil) canker after twenty years. There are no such symptoms in 

 those growing on clay, which are in the greatest vigour and beauty. Possibly 

 in the former cases the roots have got down to hard chalk. {Gard. C/iron. 

 for 1843, p. 647.) 



Clematis Vitdlba, the common hedge clematis, in the garden of the rectory- 

 house at Shenley, Herts, has two stems, each of which is as thick as the calf 

 of a man's leg. It runs up a fir tree to the height of about 30 or 60 feet, 

 although I suppose it is not more than twenty-five years old. — T. N. Shenley, 

 Sept.^. 1843. 



DuvaitA longifolia Lindl. ; Anacardidce<E. — This species, which, like the 

 others, is an evergreen, differs from D. dependcns in its leaves not being at all 

 serrated, and decidedly narrowed, not widened, to the base ; and also in 



3d Ser. — 1843. XIL x x
