fiance, which grow in Vallies, where the Ground is a 
fine whitifh Sand (and there are many fuch Vallies in 
the Ifland of Ceyhn) will in five Years Time be fit to 
have the Bark taken off: Others on the contrary, which 
fland in a wet flimy Soil,.muft have feven or eight 
Years Time to grow, before they are ripe enough. 
Again, thofe Trees are later, which grow in the Shade 
of other larger Trees, whereby the Sun is kept from 
their Roots ; And hence alfo it is, that the Bark of fuch 
Trees hath not that Sweetnefs’and agreeable Tafteob- 
fervable in the Bark of thofe Trees which grow in a 
white Sandy Ground, where with little Wet they 
fland full expofed to the Sun, but is rather of a bit- 
terifh Tafle, fomething adftringent, and fmells like 
Cam ph ire. 
For by the Heat of the Sun’s Rays the Camphire is 
made fo thin and volatile, that it rifes up -and mixes 
with the Juices of the Tree, where it undergoes a fmall 
Fermentation, and then rifing flill higher between the 
Subfiance of the Wood, and the thin inner Membrane 
of the Bark, it is at lafl fo effedually diffufed through 
the Branches and Leaves, that there is not the leafl 
Footflep of it to be perceived any where. Mean while 
that thin and glutinous Membrane, which lines the 
Bark on the Infide between it and the Subfiance of the 
Wood, attrads and fucks in all the purefl, fweetefl, 
and mofl agreeable Particles of the Juice, leaving the 
thick and grofs ones, which are pufh’d forward, and 
ferve to nourifh the Branches, Leaves, and Fruit. 
What I here mention, is conform to my own Ob- 
fervations, and I have often had Occafion to prove this 
Fad to curious Perfons by the Things themfelves. 
For if the Bark be frefh taken off, that Juice which 
remains
