\ 5» Whether the Nature of Saps afeeodingjCr the Caufe of 
of itjbe after this manner 5 wz. That io the mciftrjjght3 the 
Roots being fpungy and foft in the extreme parts 3 draw in 
moifture and ferment it s to which the Sun by his v/armth 
gives farther fermentation in the PvootSj and a pulfion upv/ards 
into the firmer parts of the Pvoots , and theace intotheBody 
and Branches, and there digefteth it ? And whetlierby the 
fame manner^the Body and Branches warmedi, and exhaufted 
in the day by the Suns heat, digeding and expending into 
leavesjdv. according to the fesfon^ draw Sap out of the lower 
part to the extremities, fo that when Digeflionj or Su&ion ( if 
there be any iuch) exceeds Puljion, Sap runs not.cJ^ vice verfai 
1 6^ If Spungy and foft wood imitates Roots in their manner 
of fliooting frefh Roots^and in the growth.after the way above 
mentioned ? 
17. Whether more foHd wood^ as Bijys^d'-r. in molfi: and 
feafonable weather laidj and fitted, or, it were grafted in 
Willow- roosts or fticks, will fhoot Roots in Layers, and grow 
as Mulberries do? I have heard that a chip of foft wood, 
laid to the end of a^^^ flip, promotes its rooting: And th^it 
ilf/^/i'err)/ Hips are eafily propagated, fet in the latter end of 
Jannarjy or beginning of Febrptary^ in a moift fea foo, not in dry 
March^ Such flips root beft^ if they be Suckers , and taken off 
with part of the old bark ^ or if they be lall years fhoots, cut 
efTfrom Arms, taken with fome older bark from the place 
where they (hot out. I have fet many formerly, which all 
throve, ! affeft to propagate them for Pear, and other (locks, 
namely Q^uinces^ Medlars, FlumS; to turn their pulp and juyce 
redj by taking grafts from fuch Tree*?, as have been grafted on 
Mulberries. ^£re^ if bloud-red Pears and red Redftrakes 
were thus railed at firftj or may be propagated^ and to what 
advantage?] 
18. ^^^^^jif Quince- ftocks conduce to make firm the pulp 
of Applesj and alter the form of them from what the Graft na- 
turally had before ?
