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 He taken off

 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. 



RENOVATION OF LEAVES. 



WHEN oaks are quite stripped of their leaves by chafers, 

 they are clothed again soon after Midsummer with a 

 beautiful foliage; but beeches, horse-chestnuts, and 

 maples, once defaced by those insects, never recover 

 their beauty again for the whole season. 



ASH-TREES. 



MANY ash-trees bear loads of keys every year, others 

 never seem to bear any at all. The prolific ones are 

 naked of leaves and unsightly ; those that are sterile 

 abound in foliage, and carry their verdure a long while, 

 and are pleasing objects.

 insinuate themselves through the thickest covert, so as 

 to surmount it all : are therefore proper to mend thin 

 places in tall hedges.
