FLOWING OF SAP. If the bough of a vine is cut 

 late in the spring, just before the shoots push out, it 

 will bleed considerably; but, after the leaf is out, 

 any part may be taken off without the least incon- 

 venience. So oaks may be barked while the leaf is 

 budding; but, as soon as they are expanded, the 

 bark will no longer part from the wood, because the 

 sap that lubricates the bark, and makes it part, is 

 evaporated off through the leaves. WHITE.

 stripped of their leaves by chaffers, they are clothed 

 again soon after midsummer with a beautiful foliage ;

 faced by those insects, never recover their beauty 

 again for the whole season. WHITE.

 every year ; others never seem -.to bear any at all. 

 The prolific ones are naked of leaves, and unsightly ;

bees, smelling strongly like honey. The foliage or
