nun be reciprocally grafted on the white beam tree. When plants are to be 

 raised from seed, the seeds should be sown as soon as the fruit is ripe; other- 

 \\ ise, if kept till spring, and then sown, they will not come up till the spring 

 following. When it is inconvenient to sow them immediately that they are 

 gathered, they may be mixed with soil, and treated like haws (see Pyrus aucu- 

 paria); and, if sown in the March following, they will come up the same 

 season. The varieties maybe propagated by cuttings, or by layering; but 

 they root, by both modes, with great difficulty. Layers require to be made of 

 the youBg wood, and to remain attached to the stool for two years. 



Statistics. In the environs of London, the largest tree is at Syon, and is 40 ft. high, with a trunk 

 8 It. in diameter, and the diameter of the head 42 ft ; one at Kew is 25 ft. high ; in Oxfordshire, in 

 the Oxford Botanic Garden, one, 30 years planted, is 25 ft. high, the diameter of the trunk 16 in., 

 ami Dt' the head 17 ft. ; in Yorkshire,' at Ilackness, 25 years planted, and 28 ft. high. In Scotland, 

 in the environs of Edinburgh, at Hopetoun House, 18 years planted, and 20 ft. high ; in Perthshire, 

 in the Perth Nursery, 4U years planted, and 32 ft. high, the diameter of the trunk 17 in., and of the 

 head 22ft. In Ireland, in Dublin, at the Glasnevin Botanic Garden, 35 years planted, and 30 ft. 

 high, the trunk 12 in. in diameter, and the head 19ft. In Sweden, in the Botanic Garden at Lund, 

 it is 4dft. high.

the base. 

 Description, 8$c. These trees bear so 

 close a resemblance to P. yf ria, as to leave 

 no doubt in our minds that they are only 

 varieties and subvarieties of that species. 

 They are found in a wild state in France, 

 Germany, and Sweden ; and perhaps also 

 in the Highlands of Scotland, where, ac- 

 cording to Sir W. J. Hooker, P. vf ria 

 varies in having the leaves more or less 

 cut at the margin. They are all well de- 

 serving of culture.

 to 30 ft. high, a native of Nepal and Kamaon, introduced in 1820. This 

 tree is remarkable for the rapidity of its growth, its long broad leaves, and 

 their woolly whiteness ; and also for being one of the very latest trees, 

 whether foreign or indigenous, in coming into leaf; being later than either 

 the mulberry or ash. The leaves are conspicuous, on their first expansion,
