tilly clay. It diflikes much wetnefs, and will not 

 thrive long in ftagnant water. In fandy or light 

 loams, it thrives beft, and becomes mod valuable. 

 In loam mixed with chy-fchiftus on whinftone 

 rock, (as at Alva), it becomes a very large tree 

 within a century. On colder, differ foils, (as at 

 Panmure, Forfarflnre, and at Arniflon, Edin- 

 burghfhire), it grows flowly, but arrives at a good 

 fize. On the banks of a river, in a loamy foil, 

 incumbent on rock, (as at Kippenrofs, Perthshire), 

 it attains to a very great fize. * On rotten rock, 

 and in an exceedingly expofed fituation, (as at 

 Prior-Letham in Fifeshire) ; it grows, as a fmgle 

 tree, to a very large fize. f

Dr Walker mentions an oak, at Loch Arkeg in Lochaber, 

 which measured twenty-four feet six inches, at the height 

 of four feet from the ground. 



* The Plane-tree (sycamore) of Kippenross, belonging 

 to John Stirling esq. is truly a noble tree ; and Nattes, in 

 hisj* Scotia depicta, ' has given a representation of it. He 

 states it to have been, in 1801, 28 feet 9 inches in girth, 

 with a stem of SO feet. He must have measured its cir- 

 cumference at the ground, as, at breast height in 1798, its 

 g?rth was only 22 feet 6 incues. In 1809, this tree was in 

 full health and beauty. Its head is very large and spread- 

 ing. T 1 ^re are also some very fine Sycamores at Newbot- 

 tle in M J -Loth? an. 



f 'he Pnor-Letham Plane measures in circumference, 

 at the surface of the ground, 21 feet 8 inches, and at the
