RENOVATION OF LEAVES. 
When oaks are quite stripped of their leaves by chaffers, they 
are clothed again soon after Midsummer with a beautiful foliage : 
but beeches, horse-chestnuts and maples, once defaced by thosé 
insects, never recover their beauty again for the whole season.— 
WHITE. 
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.—WHITE. 
BEECH. 
Beeches love to grow in crowded situations, and will insinuate 
themselves through the thickest covert, so as to surmount itall: 
they are therefore proper to mend thin places in tall hedges.— 
WHITE. 
SYCAMORE. 
May 12. The sycamore or great maple is in bloom, and at this 
season makes a beautiful appearance, and affords much pabulum 
for bees, smelling strongly hke honey. The foliage of this tree is 
very fine, and very ornamental to outlets. All the maples have 
saccharine juices.— WHITE. 
GALLS OF LOMBARDY POPLAR. 
The stalks and ribs of the leaves of the Lombardy poplar are 
embossed with large tumours of an oblong shape, which by 
incurious observers have been taken for the fruit of the tree. These 
galls are full of small insects, some of which are winged, and some 
not. The parent insect is of the genus of cyzzds. Some poplars 
in the garden are quite loaded with these excrescences.—WHITE.
