and bearing abundant crops of extremely small, but very luscious 
fruits, but which, from the rigorous winters of that deeply conti- 
nental city, could not rise above two or three feet from the ground, 
being compelled to take the form of straggling bushes, with long 
trailmg branches ascending at their extremities, which were pro- 
tected from the severe frosts of the climate by the joint agency 
of terrestrial radiation, and a natural covering of snow. The 
greater, and perhaps more prolonged heat of the summer at Phila- 
delphia, permits the Fig-tree to reach a height it could not attain 
in a climate less favourable to the perfect ripening of its wood. 
The most northerly point at which I have myself remarked well- 
grown Fig-trees on the Atlantic sea-board, was at Norfolk, in 
Virginia (lat. 36° 50’), where the Pride of India (Melia Azeda- 
rach) still acquires a timber-like size; but that town has quite a 
maritime climate at the mouth of the Bay of Chesapeake and it 
lies directly open to the Atlantic itself. In the gardens of Phi- 
ladelphia the common white Jessamine (Jasminum officinale) 
thrives luxuriantly ; and our European Ivy grows well as far north 
at least as Boston, being as much a favourite in America, as the 
Virginia Creeper (Ampelopsis quinquefolia) is with us. In that 
country the Ivy should be planted in a north exposure ; since it is 
extremely liable to suffer from the severe frosts that even in the 
southern states often succeed to very warm days in March and April. edi
