below it. On the page 38a, which comes next in the original MS. is
the sketch of an oval plan of a town over which is written "_modo di
canali per la citta_" and through the longer axis of it "_canale
magior_" is written with "_Tesino_" on the prolongation of the
canal. J. P. R.]

The main underground channel does not receive turbid water, but that
water runs in the ditches outside the town with four mills at the
entrance and four at the outlet; and this may be done by damming the
water above Romorantin.

[11]There should be fountains made in each piazza[13].

[Footnote: In the original this text comes immediately after the
passage given as No. 744. The remainder of the writing on the same
page refers to the construction of canals and is given later, in the
"Topographical Notes".

Lines 1-11 are written to the right of the plan lines 11-13
underneath it. J. P. R.]

[Footnote 10: _Romolontino_ is Romorantin, South of Orleans in
France.]
