1difficulty proceedeth from the waters of Fiume morto being low,
and the fields drained.
4. As to the particular of the Cauſes that you tell me men
preſs ſo much unto the moſt Serene Grand Duke, and to the
Prince, I have not much to ſay, becauſe it is not my profeſſion;
nor have I conſidered of the ſame: Yet I believe, that when the
Prince and his Highneſſe ſee the benefit of his People and Sub­
jects in one ſcale of the Ballance, and the accomodation of
Huntſmen in the other, his Highneſſe will incline to the profit
of his ſubjects; ſuch have I alwayes found his Clemency and
Nobleneſſe of minde.
But if I were to put in my vote upon
this buſineſſe, I would ſay, that the points of Spears, and the
mouths of Guns, the yelping of Dogs, the wilyneſſe of Huntſ­
men, who run thorow and narrowly ſearch all thoſe Woods,
Thickets and Heathes, are the true deſtroyers of Bucks and
Boares, and not a little Salt-water, which ſetleth at laſt in ſome
low places, and ſpreadeth not very far.
Yet nevertheleſſe, I will
not enter upon any ſuch point, but confine my ſelf ſolely to the
buſineſſe before me.
5. That Experiment of joyning together the water of Fiume
morto, and that of Serchio by a little trench to ſee what advan­
tage the Level E hath upon the Level I, doth not give me full
ſatisfaction, taken ſo particularly, for it may come to paſſe, that
ſometimes E may be higher, and ſometimes A lower, and I do
not queſtion but that when Serchio is low, and Fiume morto full
of Water, the level of Fiume morto will be higher than that of
Serchio. But Serchio being full, and Fiume morto ſcant of Wa­
ter, the contrary will follow, if the Mouth ſhall be opened to
the Sea.
And here it ſhould ſeem to me, that it ought to be
conſidered, that there is as much advantage from E to the Sea
through the little Trench opened anew into Serchio, as from E to
the Sea by the Mouth of Fiume morto. But the difficulty (which
is that we are to regard in our caſe) is, that the courſe of the
Waters thorow the Trench is three times longer than the courſe
of the Mouth of Fiums morto, as appeareth by the Draught or
Plat which you ſent me, which I know to be very exactly drawn,
for that the ſituation of thoſe places are freſh in my memory.
Here I muſt give notice, that the waters of Fiume morto determi­
ning thorow the Trench in Serchio (the waters of which Fiume
morto are, for certain, never ſo low as the Sea) their pendency or
declivity ſhall, for two cauſes, be leſſe than the pendency of thoſe
waters through the Mouth towards the Sea, that is, becauſe of
the length of the line through the Trench, and becauſe of the
height of their entrance into Serchio, a thing which is of very
great import in diſcharging the waters which come ſuddenly, as
