As for the vines and trees inside the enclosures of country-houses, structures or fences; as to the fences, which the commissioners after due process have exempted their owners from tearing down, and on which have been inscribed or carved the names of the commissioners who gave the permission — as to all these, nothing in this enactment prevents their remaining.

The square digit is larger than the round digit by 3⁄14 of its own size, while the round is smaller than the square by 3⁄11 of its size, obviously because the corners are cut off.61. 85 Tables showing his adjustments, and a second set of tables, prepared by Herschel on the basis of Bücheler's figures, are given at the end of the book. The aggregate of what was lost either between the intake and the reservoir or downstream from the reservoir, was 2,499 quinariae, the diversion of which, as in case of the other aqueducts, we discovered at several places. "The consuls, Quintus Aelius Tubero and Paulus Fabius Maximus, having made a report that some private parties take water directly from the public conduits, and having inquired of the Senate what it would please to order upon the subject, it has been resolved that it is the sense of this body: That it shall not be permitted to any private party to draw water from the public conduits; and all those to whom the right to draw water has been granted shall draw it from the reservoirs, the water-commissioners to direct at what points, within the City, private parties may suitably erect reservoirs for the purpose of drawing from them the water which they had received at the hand of the water-commissioner from some public reservoir; and no one of those to whom a right to draw water from the public conduits has been granted shall have the right to use a larger pipe than a quinaria159 for a space of •fifty feet from the reservoir i.e. at the point of its entrance into the City. The 40‑pipe: 7 digits plus 1⁄12 plus 1⁄24 plus 3⁄288 in diameter; 22 digits plus 5⁄12 in circumference; it has a capacity of 32 quinariae plus ½ plus 1⁄12. The water-commissioners, present or future, in any place which is now enclosed about any springs, arches, walls, channels, or conduits, are authorized to have removed, pulled out, dug up, or uprooted, any trees, vines, briars, brambles, banks, fences, willow-thickets, or beds of reeds, so far as they are ready to proceed with justice; and to that end they shall possess the right to bind over, to impose fines, or to restrain the offender; and it shall be their privilege, right, and power to do the same without prejudice. Dr. Rushkin's explanation is written for the layperson: it has a few simple equations, and a couple of diagrams, but couldn't be clearer. But our water-men,36 failing to practise the same restraint, have always claimed a part of it to supplement Julia, not, however, thus increasing the actual flow of Julia, since they habitually exhausted it by diverting its waters for their own profit. 33 side-hills 20 Misled apparently by his understanding of "fungantur", he takes the passage to mean that the water commissioners cumulate the offices of street (ambiguously and/or) grain distribution commissioners. "A quinaria was about 5,000 or 6,000 A Roman historian: he died in 21 A.D. 24 Frontinus's reckoning is as follows: The capacity of a 20‑pipe is 167⁄24 quinariae (cf. 46); the capacity of the 100‑pipe is 8165⁄144 quinariae (cf. 62); the capacity of five 20‑pipes, therefore, practically equals that of one 100‑pipe.

How large an amount of water has been stolen in this manner, I estimate by means of the fact that a considerable quantity of lead has been brought in by the removal of that kind of branch pipes. 5b The 12‑pipe: 3 digits in diameter; 9 digits plus 5⁄12 plus 3⁄288 in circumference; it has a capacity of 5 quinariae plus ½ plus 3⁄12 plus 3⁄288; is not in use.
