board and box as are shown in the accompanying
tables and diagram :—

WIDTH OF BOX TEN INCHES.

WIDTH OF BOX TWENTY INCHES.

NOTE\u2014When not more than seven sluice-heads are to be
guaged, either of the above scales may be used.

10. WATER TO BE GUAGED WHEN DEMANDED.

All holders of water rights shall place a guage-
box in their respective races, within seven days after
receiving a written notice from any person entitled to
receive a supply of water from the same source; but
when the sluice-head of water allowed by Clause 8 is
required in the natural course of a stream, it shall be
the duty of the person requiring it to guage it imme-
diately above the point where the water is required.

When water is taken from one source only, the
supply shall be guaged at the source of supply; but
if the race is fed or supplied in part by any side
stream or streams, the guage-box shall be placed
immediately below the last of such side streams.

11. NUMBER OF SLUICE-HEADS ALLOWED.

The number of sluice-heads allowed for any race
shall, in ordinary cases, be one head for each person;
provided that in races not exceeding one mile in length,
it shall not be lawful for the Warden to grant any
water-right exceeding four sluice-heads, unless there
shall appear to him to be extraordinary difficulties in
the construction of the race; and that in races exceed-
ing one mile in length where a large outlay is required,
any larger number of sluice-heads may be allowed,
due regard being had to the amount of water in the
source from which the race heads, and to the probable
requirements of the persons in the neighborhood
thereof: and provided also, that there shall be en-
gaged in making beneficial use of the water at least
one person for each sluice-head.

12. WATER NOT TO BE WASTED.

Holders of rights shall not allow any water to run
to waste; but such water shall be appropriated to the
use of the next holder of a right, according to the
date of their respective registrations.

13. KEEPING RACES IN REPAIR, BRIDGING, ETC.

The holder and occupier of any race shall keep the
same in repair, and shall make an efficient bridge
where any road in ordinary use is crossed by the race.

14. USE OF TAIL-RACES.

Any person wishing to use a tail-race, may do so
on condition of first paying to the owner of such
tail-race a proportionate share of the ex-
pense of construction, and of any enlargement
that may be rendered necessary by such
use: provided that the person so using any tail-
race shall bear an equal share in any alarm or expense
incurred in clearing the same, or such portion thereof
as may be so used, whenever it shall be necessary
to do so; and provided also, that in cases of ground-
sluicing, it shall be at the discretion of the Warden
whether a party shall be entitled to use the tail-race
of another claim, and if so, on what terms.

15. CONTROL OF TAIL-WATER.

All right or control over water shall continue in the
holder of the water-right until the water leaves any
claim, channel, or tail-race to which he is legally
entitled.

XII. DAMS AND PUDDLING MACHINES.

1. NOTICE OF CONSTRUCTION TO BE GIVEN.

Any person intending to form a dam or erect a
puddling machine, shall proceed as directed by Section
X.

2. MAIN SLUDGE CHANNEL TO BE FIRST CONSTRUCTED.

No person shall be permitted to erect a puddling
machine in any locality wherein puddling operations
have not heretofore been carried on, until a main
sludge channel shall have been constructed; and in all
cases, such main channel must be constructed by and
at the expense of the person desirous of erecting
such machine.

3. MAIN SLUDGE CHANNELS TO BE APPROVED BY
   THE WARDEN.

The position and course of all main sludge channels,
and the width and depth thereof, shall be subject to
the approval of the Warden, who shall have power to
alter and vary the same whenever it shall seem to
him necessary so to do; and upon the approval of any
such main channel, the Warden shall grant a certificate
of the same to the applicant.

4. EXPENSE OF CONSTRUCTION.

The expense of the construction of such channel
shall be borne by the persons then or afterwards using
the same, in proportion to the position of each
machine relatively to the said channel, and payment
of such proportion to the person constructing the
same shall be made prior to the granting of any
Certificate of Registration.
