daiitly with alterna tire refts every fecond or third year. The frnic 
had fcarce any core^ the kernels were very fmall, thin and empties 
oeverthcleffc the branches from the knots grew well enough t3 
replenifti aNurfcryforme. This feems to indicate the Corref- 
pondence between the Pithy part, Heart or Timber ^and the 
Seeds. And more to confirme this 5 Ayoung tree grew like a 
Sucker fiomthe only found Root of the aforefaid Apple- tre«. 
This tree grew ftraitcr then others of the fame kinde ufoally 
do 5 of whi^h I^onceive the caufe to be this : Suckers arc com- 
monly barren a pretty long time 5 and this continued barren , til 
theftem wasftrong enough to bevthe fruit which loaded the 
branches. But that, which makes to ourpurpofe, is this 5 AU 
the fruit of this young tree had fill and found Kernels ^ and though 
it was the fame fruit , growing from the Root of the fame tree 5 
yet it feem'd^not altogether fo tender, delicious and juycy, as 
thefmit oftheold tree; nor yet was the tree fo fruitful!. The 
Sap in the old tree was lefs diverted, it feems, to ftiftaine the 
life of the timber, which was now confuted ; and thereby was 
ivholy appropriated for the leaf, bloflbm, and the pulp of the 
fruit, i'or 1 do not undertake^ that the Sap yeildsno relief to 
fuftainthc life and growth of the timber #rir;Mn7y, ind whilft 
the timber is entire ; but I rather conceive , that there is a more 
immediate and peculiar relation between the Sap and Pulpous 
fruit, and the like between the Timber, or whole ftock, and 
the Hoot of the Tree , to tranfmit the fame fpirit and nature to 
the Seed of what kind foever it be. 
Some are of opinion , that there pafles into the Timber no part 
of mecr Earth to fuftain the life and growth the Plant, but 
it only feeds on the fucculent part afcendingby the Roots, and 
on the Air, and the moifture, which the Dews of Heaven , the 
Rainy feafons , and the Air afford . And if we confidcr , that 
feme lofty trees grow upon the Rocks, where little or no earth 
can be founds asalfo, how largly the Oak and Pear-tree grows 
and fprcads , and how nwny years the one bears Acorns, the o- 
ther Pears > fomtimes to the quantity of yeilding5vor 6. hogs- 
heads yearly (as I have known them do 5 )and in coraparifon
