der growth of fruit, leaves, or uppcrmoft lhoots in tops of trees, 
and yearly flioots in extreme parts. If by Obfervation this be 
verified, then hence we have a probable reafon of Suckers rob- 
bing fruit, viz. becaufetill the whole tree be filled of Sap, the 
fruit cannot be ferv'd in the uttermoft branches : wherefore not 
only Suckers, but all fuperfluous not-btaring Branches are to 
be carefully cut away before, or at the entrance of the Spring. 
Hence alfo it is to be inquired. Whether there be not fome pe- 
culiar feafons to caufe Timber, Branches and Fruit to increafe$ 
and whether the fir(i feafon of the ftirring of Sap be moll proper 
to increafe Roots, or the lafl$ and in the middleraoft feafon, 
whenit reaches the top-moft branches, propereft for Fruit i Al- 
fo, whether what they call Blafiwgi be not fometimes for want 
of fupply of Sap at thofe feafons fubjedt to blading ?. And whe- 
ther, by difcreet watering and manuring, Trees that bear only 
fome years, may be caufed to bear yearly, which fome Fruit- 
trees are obfeiv'd to do in all foils, and others in fome foils, and 
not otberfome..

diverfity of pullion, and plenty of fap therein depending, what

£u£re farther, Whether pruning the roots, by diverfifying 
the Pulfion, -tnay not alfo promote the fruitfulnefs, by taking 
of thofe that lead immediately to wood, i.e. the fbortefti and 
of the latter years (hooting, and as it were the Suckers of the 
root, and leaving andnounlhing thofe which feed fruit efpeci-

years ftiooting ? And, whether cleaving roots fo, as to caufe new 
ones to fpring from the inner part of the cleft , held open by a 
ftone, do not help fruitfulnefs for this caufe t
