The Prickly Ash is a small tree rarely at- 

 taining the height of 40 or 50 ft. with trunk 

 12-18 in. in diameter, but visually is much 

 smaller and often shrubby. Its tendency when 

 isolated is to develop a broad rounded top of 

 iii;>ny spiny branches, and its peculiar bluish 

 gray bark of trunk is sure to attract attention. 

 This is smooth and studded with scattered 

 barnacledike corky bossess, each tipped with 

 a thick sharp spine which, however, finally 

 falls away. A fancied resemblance in these 

 spiked trunks to the club of Hercules has sug- 

 gested its specific name, and the hooked spines 

 of its branches have given it its apt collo- 

 quial names " ^Va^t'a-bit " and " Tear-blanket,'' 

 while its pungent bark has given it the name 

 "Sting-tongue " among the southern negroes. 

 This property, too, as a source of relief in 

 tooth-ache has caused it to be known as 

 Tooth-ache tree. 



Its wood is light, a cu. ft. when absolutely 

 dry weighing 31. .51 lbs., soft, close-grained and 

 of little value. Its bark, however, is highly 

 valued among the southern negroes for the 

 medicinal properties mentioned of the genus. -
