Estimates and preparatory studies for canals (1014. 1015).
CANAL.
The canal which may be 16 braccia wide at the bottom and 20 at the
top, we may say is on the average 18 braccia wide, and if it is 4
braccia deep, at 4 dinari the square braccia; it will only cost 900
ducats, to excavate by the mile, if the square braccio is calculated
in ordinary braccia; but if the braccia are those used in measuring
land, of which every 4 are equal to 4 1/2 and if by the mile we
understand three thousand ordinary braccia; turned into land
braccia, these 3000 braccia will lack 1/4; there remain 2250
braccia, which at 4 dinari the braccio will amount to 675 ducats a
mile. At 3 dinari the square braccio, the mile will amount to 506
1/4 ducats so that the excavation of 30 miles of the canal will
amount to 15187 1/2 ducats.
