" The Bees shall loathe the flow'r, and quit the hive. 

 The ^aUflJ^iS on boggy ground shall cease to thrive. 

 Ere scornfu' queans, or loss o' worldly gear. 

 Shall spoil my rest, or ever foi-ce a tear." — Allan Ramsay.

 On a bank overhanging the inn at Abbey St. Bathans. In the Snail's 

 Clengh amidst the Lammermuirs ; and the name of the ravine, which 

 divides Berwickshire from E. Lothian, is probahly derived from 

 its former wooded character, to which this tree, to judge from the 

 scions that remain, must have mainly contributed. Common in plan- 

 tations. — " I 'm trembling a' o'er like an aspen leaf," is a familiar 

 comparison with our common people. The constant tremulous motion 

 of the leaf is produced by the peculiar form of the foot-stalks, and 

 is so familiar a phsenomenon as to have attracted general attention : 



" his hand did quake. 



And tremble like a leafe of SiSptn greene." — Spensek. 



" Her tongue still chats of this and that. 

 Than aSjlute leaf it wags more fast ; 

 And as she talks she knows not what. 



There issues many a tnithless blast." — H. Gifford. 



A legend, originating in reverential awe, ascribes the trembling of the 

 leaf to a cause which Mrs. Hemans has prettily versified : 



" Oh ! a cause more deep. 

 More solemn far the rustic doth assign 

 To the strange restlessness of those wan leaves. 

 The Cross, he deems, the blessed Cross, whereon 

 The meek Redeemer bow'd His head to death. 

 Was form'd of aSpcn wood : and since that hour 

 Through all its race the pale tree hath sent dovm 

 A thrilling consciousness, a secret awe 

 Making them tremulous, when not a breeze 

 Disturbs the airy thistle-down, or shakes 

 The light lines of the shining gossamer."
