,'$2 THE OAK. 



of all trees. The painter will perhaps stop and admire 

 the stately growth of the same tree ; he will notice the 

 symmetry of its form, and watch the brilliant lights play- 

 ing about its thick foliage, but he will feel no desire to 

 transfer it to his canvas. There must be no perpendicular 

 or parallel lines about the object of his choice ; no hemi- 

 spherical evenly-shaped head ; no arms of equal diameter 

 springing from the main stem at the same angle, and ex- 

 tending to an equal distance all round. But show him a 

 veteran patriarch, whose gnarled trunk is eaten out by 

 the frost of centuries, whose knotted limbs are fringed 

 with ferns, and mottled with innumerable mosses and 

 lichens ; even if but a scanty foliage clings to branches 

 which have been shattered again and again by the tempest,

 assemblage of hoary, sapless antlers ; and you will hear 

 him exclaim, " I go no farther to-day ; this is the tree for 

 a picture ! " And move he will not, until with his pencil 

 he has produced the same image which the poet has 

 conjured up with his pen.

 "Whose foot on earth hath got but feeble hold, 

 And, half-disbowelled, stands above the ground ; 

 With wreathed roots, and naked arms, 

 And trunk all rotten and unsound." SPENSER. 



About the end of April the season for barking com- 

 mences, and to this process Oaks, both old and young, are 

 equally subjected ; those of from twenty to thirty years' 

 growth, however, being preferred. Oak bark is occasionally 

 used in medicine, and is employed also as a dye, but is 

 most valuable for the principle called .tannin, which is 

 indispensable in the manufacture of leather. Every part of 

 the tree, indeed, abounds in astringent matter, and even 

 the leaves and sawdust will tan leather, linen cloth, and
