ton of the proper proportion chsrgeable to the
Government A. Yes, sir.
By Mr.. Jewett: Q. That was IN existence BE-
fore you made the first column In the schedule
wasn't III A. No, cir: we got It up nrst,
think, in the spring 6iS7S.
Q. These mapsi A. Yes, SIR.
Q. Who got them upf a. Well, gentle
them.
Q. I am not speaking of the sewers. Who
By Mr.. Merrick: Q. Who made the draugh.s
Of the mapsi Who draughsed this mapai A.
This Is engraved.
Q. Bywhomi A. By Peterson & ]. Entho6er.
q. Who prepared III A. II Is prepared frou
the official plsts, as he states, and We find 10
Q. Your Judgment as TO the number Of
linear feet depends upon the correctness OF
this mapf A. Yes, SIR; Of course in any map
there may be some slight variations.
Q. You don't know that this map Is correcti
A. Well, I think It Is, as well as can judge.
There are some few errors in 1t, but very FEW.
Like any other maps, Of course BY scaling 1t
you may possibly occasionally fall short or
overrun.
Q. The party who draughted this map did It
upon certain scalef A. Yes, sir $50 feet to
the inch.
Q. Don't you know as an engineer that that
Is the least reliable Of all kinds of evidences
map prepared in that Wsyi As an engineer,
would you, under any circumstances, rely upon
map prepared in that way, as being accurate
in the measurement of distancesl A. Well,
the difference I don't think exceeds two per
cent. at the utmost, unless the map has been
very carelessly drawn.
Q. Doesn't 1t depend entirely upon the skill
of the man who makes III A. Yes, sir; IL de-
ponds q great deal upon that.
Q. And the purpose for which It Is madei
A. Yes, sir. -.-, 60,
@. AS general thing, Is Il intended to rep
resent accurately distances; isn't 1t intended
simply to represent localitiesl A. No, sir; in
this case he intended it to be as nearly correct
as possible. The size of the lots could be
scaled, and, of course, In the lots a couple of
inches or feet make quite difference. 1t was
his intention for that purpose to have the map
as accurately drawn Us this scale will allow It.
Q. State whether the correctness Of your
calculation does not depend on the accuracy of
this mapl A. Yes, sir.
Q. With the making of this you had nothing
to dol A. Of course, in the preparation of
vouchers the actual measurements of the ground
ought to have precedence always.
@. But the means you ought to have taken
you did not take-the actual measurements
A. The statement you refer to is mere COM
parative statement. The variation can be but
Slight.
By Mr.. Christy: Q. Can you, by referring to
that map, inform US whether q sewer is re-
ported to have been constructed ia front Of
square 1851 A. There Is none entered here.
Q. Do you know the fact that q charge has
been made against the property holders own
ing property upon that square for the sewer as
constructed, and bills rendered thereforl A.
do not know It from my own knowledge; that
is branch with which had nothing to do at
all.
Q. If that has been done, It is an errorl A. I
suppose it to DO an error.
Q. lift has been constructed, it would appear
on that map? A. 1t does not, fully entered up.
There are few sewers which have been con-
structed which are not entered yet, but don't
think any arc In tina. square.
BY Mr.. Stanton: Q. Have you had any
occasion to satisfy yourself as to the care with
