ously from the stool. The wych, or broad-leaved elm, however, is certainly of 

 natural growth in this country ; though it is more common in Scotland, and the 

 northern parts of England, than in the southern counties. For the same rea- 

 sons, he cannot allow the lime to be indigenous, though in some years the seed 

 becomes mature. The greater part of the limes, which we now see in every part 

 of England, have been planted since the time of Charles the 2d, and were intro- 

 duced by a French gardener, whose name was Le Notre, at the same time with 

 the horse-chestnut. The greater maple, or sycamore, as it is improperly called, 

 is certainly a foreign tree, though very common in Scotland, the northern coun- 

 ties of England, and some parts of Wales. He never saw the tree but in a 

 hedge-row, avenue, or clump; it must be admitted, however, that its seed 

 comes to its full perfection in almost every year. 



Mr. B. next mentions some trees and shrubs, which he had doubts whether 

 they are natives of Great Britain or not, though they are so considered by the 

 botanists ; he cannot pretend however to be so positive as in some of the former 

 articles. He never saw the yew where it grew in large masses, or appeared to 

 have been sown by the hand of nature. The most considerable numbers which 

 he has happened to meet with are on some of the Surry hills: these however 

 scarcely in any instance cover more than an acre of ground. If he should be 

 right in supposing that this tree is of foreign growth, it may then be perhaps 

 contended, that we have no ever-green tree or shrub which is indigenous, except 

 the holly, the juniper, and the ivy. Every church-yard indeed proves, that this 

 tree has been for many centuries introduced into England ; it seems however very 

 extraordinary, that we should have no accolint when, or for what purpose, this 

 so very general a practice has so long prevailed with us. To the catalogue of 

 doubtful trees, he also adds the abele, or white poplar, never having seen it grow- 

 ing according to the rules above laid down with regard to indigenous trees. He 

 has likewise his suspicions with regard to the privet and spindle tree.
