After the lnvent$r had in the Dedication appeal 'd to Don 
Geron'mo de Camargo as an Experimental Judge and Eye-wit- 
nefs of the Performances of this Inftrument , and taken oc- 
cafion to celebrate the happinefsof the latter Ages upon the 
account of the Inventiom of many Excellent things , as the 
Ufe of the Loadftone <Gun-powder ; Great Ordinance > Prin- 
ting 5 the Ordering of Qaickfilver to feparatethe nobler f- om 
the bafer Metals 3 the Perfeding of Watches by Pendulums ^ 
and many more: Aker this, I fayjit isreprefented, 
Firfi, That both the Ancient and Modern H^jsbandmcn 
have cigreed , that the Perfediion of Agriculture confided in 
fetting the Plants in proportionable fpaces^ and giving fuifici- 
ent depth to tl e Roots, that they may fpread enough ^ to 
receive that nourifliment from the ground, which isneceflary 
to produce and ripen the fruit: For which reafonwefee, thac 
Plants are fet in rowes by rale and meafurc , as the Vine, Olive- 
trees, and other Truit-Tiees; and in Gardens, the Herbs, 
and Flowres are planted and fow'd with fome order and diftiniii- 
on 3 fo that their over-neariiefs andtheconfufion of their Plan- 
tation may not Linder their growth. 
Secondly, That cafe hath not been had in the practice of this 
irapoitant part of Husbandry, fince even at tWs day all forts 
of Seeds ^ of Corn and Grain , are fown by handfuls, throw- 
ing them diit by aime , lieedlefly and by chance ( counting it 
too tedious and chargeable to fet them one by one in large 
fields 5) whence we fee Corn fow*d in fome places too thick, 
inothers too thin, and the greater part of it not cover'd , nor 
deep enough , whereby it is mt oniy exposed to be eaten by 
Birds, but alfo^ in Cold Coimtrys, to be fpoylcd by Froft^and 
in Hot R egions, by t he Sun. 
Thirdly, That, iTpon thefe Confiderations , He (^"D.^^ 
feph de Lmatelioy hath, fome years fince, given himfelf to 
inventan Inftriment 5 which with great cafe , and with litlc 
charge or trouble , feis grain in order and propcx-f ion , for the 
fparing a great quantity of Seed-corn, and enriching tlieCrop; 
And that after much Experience he hath perfeded and reduced 
anto prafticc thofe ideas^ producing an Inftrument, which
