Scottish ArhoricuUural Notices. 1^1 



^^ Silver Fir {A^bies Vicea). — 'The largest two noted in my book 

 are at Roseneath, measuring about 20 ft. in girth : the two trees 

 containing 1053 cubic feet. In 1829, I measured the largest at 

 Dupplin, at 3 ft. from the ground: it girthed 13 ft. 2 in., con- 

 taining 380 ft. of measurable wood. In 1832, I measured a silver 

 fir near Arniston House, and found it to girth 13 ft., and of 

 similar dimensions with the one at Dupplin. 



" Pinaster ( ^inus Pinaster). — On the estate at Gray, near the 

 church, in 1831, I measured a tree of that species; and found 

 its girth, at 3 ft. from the ground, to be 8 ft. 5^ in., with a bole 

 of 30 ft. in length, reckoned to contain 50 cubic feet. 



*' Black Italian Poplar [Populus acladesca). — One planted by 

 the burn side, at Tippermallow, near Methven, on May 5. 

 1776, contained, in 1802, 40 cubic feet ; in 1812, it contained 

 67 cubic feet, girthing 6 ft. 9 in.; in 1827, it contained 198 ft., 

 length of bole 59 ft., girth 9 ft. 8 in. ; and, in 1831, it girthed 

 10 ft. 4<|^in. One of the same species, at Barnhill, near Perth, 

 measured in girth 10 ft. 9in. ; one at MoncriefF House mea- 

 sured in girth 10 ft. 10^ in. in 1832; one at Taybank, near 

 Perth, planted in 1785, girthed 10 ft. 7 in. in 1834. 



" The Necklace-beariitg Poplar [Vopulus monilifera). — One 

 of this species, growing at Methven Castle, planted about fifty- 

 five years since, girthed 6 ft. 8 in. ; when a black Italian poplar, 

 planted at the same time, girthed 8 ft. 10 in. The proportional 

 growth of poplars I take to be thus : — Black Italian, 10 ft. ; 

 White, 9 ft. ; Lombardy, 7 ft. ; and Balsam, 4 ft. 



" Liriodendron Tulipjfera. — The largest in Perthshire is 

 undoubtedly the one at Gorthy. In 1829, it girthed 6 ft. 6 in. 

 at the smallest part of the bole. At the height of 6J ft. it 

 divides into two limbs, the largest girthing 5 ft. 3 in., and the 

 smallest 4 ft. 5 in. ; terminating in a large round top, about 

 40 ft. in height : planted between seventy and eighty years iigo. 

 In 1830, I found the tree of that species, at Pitcaithly, to girth, 

 at 1 ft. from the ground, 6 ft. 8 in." (Observe, Mr. Mitchell's 

 measurement, formerly sent, was taken at 3 ft. from the ground ; 

 and was, in 1834, 6 ft. 6 in.) " It divides into two, at the height 

 of about 16 ft. : total height, about 40 ft. 



" Foreign Birches. — At Delvin, a 5etula joopulifolia girths 

 5 ft. at 3 ft. from the ground ; unhealthy. At Methven Castle, a 

 J5etula papyracea, 4 ft. 6 in., healthy ; and a jBetula nigra, fifty- 

 five years planted, girths 3 ft. 5 in. Others, in a close plant- 

 ation, girth 2 ft. 3 in., boles 25 ft. high. 



" The largest poplar thought to be in Scotland is supposed to 

 be a white Egyptian at Kelso, girthing 23 ft. at 3 ft. from the 

 ground." (Here Mr. Bishop describes some species of the 

 genus Pinus at Hopetoun House; but as your intelligent cor- 

 respondent Mr. Smith will, likely, furnish you with accounts of
