' We know, that of all foils this is the moll fa- 
yourable to beech, white-beam, juniper, viburnum, 
traveller’s-joy, and to many of the herbaceous tribe; 
tiiOLigh not only fuch, but many foreign plants, will 
increafe alfo in foils that are not the moll fuitable 
to them. 
In the woods here*, and at a diftant place, I find, 
not unfrequently, feedlings of the Scotch-pine (which 
whether indigenous of Scotland, or not, may be 
doubtful), fpruce-fir, horfe-chcfnut, walnut, and 
perhaps more than I can at this time recolledl. Of 
the four kinds mentioned, fome trees, notwith- 
fianding the tread and the browfing of cattle, now 
grown to a confiderable height, I am certain were 
not planted. Of the three firft there are many not 
far off, that were planted, and probably may in moft 
feafons bear perfedl feeds : but of the walnut I do 
not know that there is, or has been, within half a 
mile of the firfi-mcntioned woods, a tree that has 
produced a nut mature enough for vegetation. It is, 
however, cafy to conceive, that the nuts may have 
been brought from a much greater difiance by- birds, 
or other animals, and dropped accidentally, or 
hoarded and forgotten, or perhaps not needed. 
In a fhrubbery, many years left to nature, I have 
obferved very numerous progenies of various foreign 
fhrubs, both from the feeds and roots ; and it is well 
known to gardeners, that many of' their once choice 
flowering herbs are apt to multiply in the way 
of fuckers, while the feeds of others fow themfelves 
fo plentifully, , as not eafily to be kept within 
bounds. .
