The Flowering ash (Fraxinus Ornus*) is a small tree of 

 about 20 feet, growing plen' 'fully in the south of Europe, 

 and is also found sparingly in this country. Its chief beauty 

 lies in the beautiful clusters of pale or greenish- white flow- 

 ers, borne on the terminal branches in May and June. The 

 foliage and general appearance of the tree are much like

 a good deal the Carolina Fringe tree. In Italy a gummy 

 substance called manna exudes from the bark, which is 

 used in medicine.

 the taste is in favor of geometric plantations. In Germany 

 and Holland it is a great favorite for bordering their wide 

 and handsome streets, and lining their long and straight 

 canals. " In Berlin,"' Granville says in his travels, " there 

 is a celebrated street called ' unter der Linden' (under the 

 lime trees,) a gay and splendid avenue, planted with double

 that the American kind is so little known, that it is difScult to determin* 

 whether it is a different species or only a mere variety of the European.
