214 A BUNCH OF HERBS. 



one that was so. Some seasons the sugar-maple 

 yields much sweeter sap than at others ; and even in- 

 dividual trees, owing to the soil, moisture, etc., where 

 they stand, show a great difference in this respect. 

 The same is doubtless true of the sweet-scented flow-

 violet, but, like that of the hepatica, comes nearer 

 to the odor of certain fruit-trees.

 perfumed breath falls" upon you as its cool shadow 

 does a few weeks later. 



After the Linnaea and the arbutus, the prettiest 

 sweet-scented flowering- vine our woods hold is tho
