Trees, of both Sorts, quite through their Bark, 
and then the Juice Blues forth again, and runs into 
larger Grumes. The Quantity is often fo great that 
it flows down to the Bottom of the Tree, and there 
forming itfelf into large Maflfes, is left a Day or two 
to thicken. Afterwards it is divided into Pieces 
and dried in the Sun. This is termed Manna coafta, 
and by the Inhabitants Forzata and Forzatella , be- 
caufe it is only obtained by making a Wound in the 
Bark. Its Colour is not very white, but rather red- 
difh, and often inclining to Black, by Reafon of 
the Dirt and Impurities which are mixed with it. 
A third Sort, which is gathered upon the Leaves 
of fome Afh-T fees, is called Manna di frondo . In 
July and Auguft , about the Middle of the Day, it 
exudes fpontaneoufly from the Leaves, like fmall, 
tranfparent, liquid Drops. Thefe becoming dry 
with the Sun, concrete into white Grains, of the 
Bignefs of Millet or Wheat ♦, fo that the Leaves 
fometimes appear in Auguft as if they were covered 
with Snow. Notwithftanding this Manna was very 
much ufed formerly, it is now rarely met with in 
the Shops in Italy^ by Reafon of the Difficulty 
which attends the gathering it. 
The Inhabitants of Calabria diftinguifh the Manna 
obtained by Incifion from Trees which have yielded 
fome of their own Accord before, from that which 
is drawn from fuch wild Afh-Trees as yield none of 
their own Accord. The latter is accounted more va- 
luable, as the fpontaneous Manna of the Trunk is 
preferred to the others. Sometimes alfo, when 
they have cut the Bark, they infert Straws and 
flender Twigs in the Wounds. The Juice, as it 
runs along thefe, is infpiflated, forming long fta- 
la&ical Grumes, like Icicles. When they have ac- 
quired a proper Size, the Straws and Twigs being 
drawn out, they are laid in the Sun to dry, and af-
