Each of thefe trees bore plentifully that feafon 
though, in general, reckoned a bad year for fruit. 
This induced me, in the beginning of Auguft 
I7fp, to make the like experiments on feveral other 
young trees ; fome, that had not yet borne any fruit, 
and others, that had borne but a fmall quantity; par- 
ticularly, two young pear-trees, that never yet had 
any bloom. I treated the main arms of one of thefe 
in the manner already defcribed, and alfo feveral of 
the branches, that grew on thefe arms; likewife one 
of the arms of the other pear-tree. The firfl: of thefe 
bore a furprizing quantity of fruit laft fummer ; and 
the circumcifed arm of the other bore a moderate 
quantity, though no other part of the tree had any 
appearance of bloom. 
I made alfo the following experiments, on two 
branches of different young apple-trees, as nearly of 
the fame fize as I could find. I cut off the bark of 
thefe, as exadtly as I could by a gage ; changing 
them, and putting the bark of the branch of one 
tree on the branch of the other. I find, by the mi- 
nutes I took, that a fmall flip of wood came off with 
the bark of one, and the bark of the other had a 
leaf-bud on it ; which branch had alfo two apples 
growing on it. The bark of each of thefe healed 
perfectly, and the apples remained on, and ripened 
with the reff : the leaf-bud pufbed forth leaves, and 
both the branches bore fo very plentifully the laff fum- 
mer, that one broke down with its load; and the other 
would alfo, probably, have buffered the fame fate, 
but that I had it fupported. Thefe were both non- 
pareil apple-trees, planted in afparagus beds.
