bout 2 ft. high, extending to the springing line
of the dome, was then put in, and the dome forms were set up on it. The
idea was that this 2-ft. form could be knocked out piece by piece and
the weight of the dome form taken on wedges to the last 6-ft. form,
these wedges being gradually slackened down in order to allow the dome
form to settle clear of the dome. As a matter of fact, this was done,
but the dome forms, being very tight, did not settle, and had to be
pried off a section at a time. A similar method was used for slacking
down the roof forms, with similar results.

After the dome forms had been put in, the concrete was carried up
approximately to the elevation of the bottom of the rings. Small neat
cement pads were then put in and accurately leveled, and on these the
steel rings were placed, and the steel tank was erected.

In order to insure a perfectly round tank, each course was erected
against wooden templates accurately centered and fastened to the inside
scaffold. The tank is the ordinary type of light steel, the lower course
being 3/16-in., the next, No. 8 B. w. gauge, the next, No. 10 B. w.
gauge, and the remaining four, No. 12 B. w. gauge.

Work on the foundation was started on August 15th, 1908, and the tower
was not completed until April 1st, 1909. Much time was lost waiting for
the delivery of the steel, and also owing to a period of very cold
weather which caused entire cessation of work for about one month.

The tower as completed presents a striking appearance. In order to
obliterate rings due to the successive application of the forms and to
cover the efflorescence so common to concrete structures, the outside
was given two coats of neat cement wash applied with ordinary
calcimining brushes, and, up to the present time, this seems to have
been very effective in accomplishing the desired result.

SCAFFOLD FOR WATER TOWER]

Irregularities due to forms are unnoticeable at a distance of 200 or 300
ft., and the grouting gave a very uniform color.

The application of two coats of cement wash cost, for labor, $97.68, and
for material, $15.18, or $1.32 per 100 sq. ft., labor being at the rate
of $2.25 per 8 hours and cement costing $2.53 per bbl. delivered on the
work.

The tower was designed by Arthur L. Adams, M. Am. Soc. C. E., under
whose direction the plans for all the work of remodeling the water-works
system were prepared and executed. The for
