We may spout that water much heigher by augmenting ye height of the pipe MN.

  The beauty of spouts in their uniformity and transparantly in their going out of ye passage without scattering as well as in their height.  We have sought many ways to make ye passages, whereof there is some we prefer before ye rest for many reasons.  Ye worst are those which are made cylindricall;  for they very much stop ye height of ye spout, ye conical stop it less:  But ye best way is to pierce ye horizontal plate which stops ye end of ye pipe of ye conduit with a smooth and polished hole taking care ye ye plate be perfectly plain polished and uniform.  Here is some experiments which I made.  Having a pipe of tin of 15 foot heigh A B C and having pierced it in D with a hole of 3 lines, ye spout was perfectly beautifull and went to 14 feet:  But ye pipe having been made heigher to 27 foot, and having a hole in it of 6 lines ye spout went but to 12 feet being much scattered and separating itself into many drops, wch proceeded from thence that ye water wch maintained ye spout was with force pushed across as is seen In ye second figure which represents a portion of the pipe B C.  For ye water E D and F D wch cometh from ye sides hath a great swiftness cross wise, wch carrys it to D L and D M;  and G D is carried to D N and H D to D O, wch scatters ye spout, because the lettle water which comes directly from P in D is not sufficient to straiten it.

To avoid this fault I put in D a passage of an inch long and an inch large as is seen in ye 3d figure, where B C represents ye part B D C of ye first figure;  we pierced it with a hole of 6 lines the small upright pipe D Q M Q then ye spout was very fine, and was elevated 3 or 4 foot heigher.

Transcription Notes:
mandc: Reviewed and amended image descriptions. Note that the initial letter in the word "In" looks more like a J in a more modern alphabet. The letter J did not always exist as it was missing in the Latin alphabet and not universally adopted in English until sometime around the sixteenth century.
