relative to competitions for school houses
at Woodland and Sacramento, of which
the membership was aware throughthe
notice sent out and that it was hoped in
the case of the Sacramento school house
that the program would be inodified to
conform to the institute code.

Mr. Faville, for the civic improvement
committee, reported that there had been
no meeting of the committee, but ex-
pressed satisfaction at the appointment
by the mayor of a civic center commis-
sion, consisting of Messrs. Howard, John
Reid and Meyer.

Mr. Mullgardt, chairman of the com-
mittee on architectural league and educa-
tion, advised the members regarding the
postponement of the convention of the
architectural league of the Pacific Coast
at Los Angeles to April, and stated that
the drawings to be submitted for the
traveling scholarship would be exhibited
in- San Francisco.

Mr. Bakewell, of the housing commit-
tee, stated there was to be a conference
regarding the tenement house law, at the
board of public works, and suggested that
a special committee other than the hous-
ing committee be present.

The following communications were
ordered received and placed on file: from
Mr. Chas. T. Mott, his resignation from
the Chapter, owing to his return East:
from Mr. A. F. Rosenheim, president, and
Mr. Fernand Parmentier, secretary, of
the Southern California Chapter, A. L A.,
regarding the postponement of the Archi-
tectural League convention until the an-
nual meeting of the State Board of
Architecture in April, and inviting the
members to Los Angeles at that time;
from the General Contractors' Associa-
tion, regarding contract forms; from the
Michigan Chapter, .\. L A., copy of min-
utes of annual meeting of January 16.
1912, and from Mayor James Rolph, Jr.,
in regard to meeting of the board of
public works to consider the tenement
liouse law.

On motion made, seconded and car-
ried, the chair was empowered to appoint
a special committee to consider the mat-



ters contained in the commimication from
the General Contractors' .Vssociation.

The secretary called the Chapter's at-
tention to the report submitted by the
building laws committee at the meeting
of February IS, and which was amended
at that meeting, and stated that no action
had been taken regarding the appoint-
ment of a committee to submit the pro-
posed ordinance to the proper authorities.
On motion made, seconded and carried,
the matter was left in the hands of the
original committee for proper action.

Mr. Howard expressed the appreciation
of the Chapter at having present the dis-
tinguished gentlemen who were to be of
the advisory council of the Panama-
Pacific International Exposition, and called
on Messrs. Hastings, Richardson, Bacon
and Farquhar, of the commission, all of
whom made remarks appropriate to the
occasion and appreciative of the architec-
tural opoortunities afforded by the site and
scope of the 1915 Exposition.

At the conclusion of the remarks^ the
gentlemen mentioned above were given a
rising vote of thanks by the Chapter.

Form Partnership

Messrs. William Wilde and Erwin
Schaefer have formed a copartnership
for the practice of architecture and have
taken offices in the .-Mbany block, Oak-
land. Mr. Wilde was formerly with
Henry F. Starbuck, now of Fresno. The
new firm has quite a little work under
way, including a $15,000 city hall at Mar-
tinez, a brick store building in San Fran-
cisco, a store and apartment house for
C. S. Kelson in Oakland, and several resi-
dences.

•Messrs. William Coates and Harry
Traver have formed a partnership and
have taken a suite of offices in the Head
building, San Francisco. Both young
men have had considerable experience in
following their profession and should
make a success of their business venture.
Coates was formerly State Architect,
while Traver has for some time been
connected with the City .Architect's office.
Before coming to San Francisco, Traver
was a member of the drafting force in
the State .Architect's office at Sacramento.

New Certificated Architects

The following have been granted cer-
tificates by the State Board of .Architec-
ture for the practice of architecture in
California: Richard D. King, 1647 Mid-
dleton place, associated with Architect
Edward Cray Taylor, 528 Consolidated

Annual Meeting of Oakland Architect-
ural Association

The Oakl'ind Architectur.il Association
held its second annual banquet in February.
The principal speakers were Mayor F. K.
Mott. Harry Anderson, commissioner of
public works ; Walter J. Mathews, C. W.
Dickey. J. J. Donovan and Louis S. Stone.
C. W. Childs, who is connected with the
board of education in Oakland, displayed
some interesting pictures and photographs
of the modeling work of the new city hall,
while Donovan discussed entertainingly the
designs and models as they were thrown
upon the screen. Pictures were also shown
which were readily understood by those
present to represent local people and condi-
tions. Those present were : Hon. F. K.
Mott, H. S. Anderson, W. J. Mathews, C.

The following officers were elected for
the ensuing year : Louis S. Stone, presi-
dent ; C. W. Dickey, vice-president ; D. V,
Deuel, secretary-treasurer. There were five
new members elected. The association is
increasing its membership rapidly.



Architects Parker and Kenyon Busy

.Architects Parker and Kenyon are busy
with considerable high class country
work. They have a $20,000 bank building
at Princeton, a brick library building at
Dixon and a $30,000 Elks building for
Nevada City. Walter Parker, a member
of the firm of Parker & Kenyon was
done an injustice in the January number
of this magazine by a misleading caption
beneath the full page cut of a bank and
office building on page 94. Mr. Parker
designed the structure and not Mr. F.
W. Fitzpatrick. We are glad to make
this correction for Mr. Parker whose
ability as a designer is recognized.



Phelan to Build Hotel

James D. Phelan will build a seven-
story $90,000 hotel on Market- street, near
Seventh. San Francisco, from plans now
being prepared by William Curlett &
Son. Phelan is having built in Los Gatos
a beautiful Italian villa, also from plans
by Curlett & Son.



Los Angeles Architects Meet

"Ceramics and the History of Clay
Products in -Art and Architecture" was
the subject of an interesting paper by
Mr. William ^^'ade before the architects
at the January meeting of the Soutlicrn
California Chapter of the American Insti-
tute of .Architects. Mr. Wade is the
senior member of the firm of J. & W.
Wade Company, which has been engaged
in the manufacture of tile and other clay
products at Burslem. England, since 1867.
The speaker traced the history from the
time of Babylon and Egypt to the present
day and showed how the diffusion of
knowledge in the art followed in the
wake of the conquering armies as each
nation rose and fell. The height of per-
fection attained bv some of the ancient
peoples cannot in many respects be
equaled in the present age. although some
of the lost art is continually being re-
gained.

.An important matter that was thor-
oughly discussed at the business session
was the ordinance, which has been passed
bi' the council and is awaiting action bv
the mayor, providing for the elimination
of the chemical tests from the require-
ments of the cement testing section of
the city building ordinance.

.Architects Cunningham & Politeo. of San
Francisco, announce the removal of their
office from the Chronicle to the First Na-
tional Bank building. This firm has just

Richard Martin, Jr., following the ex-
ample of E. M. Lazarus, William Travis,
and other prosperous Portland architects

incidentally load uo with new ideas and
other inspirations, by taking a year's
tour through European countries. May
Brother Martin have a fine trip and
"homeward fly" at its close.



Architects Welsh & Carey Busy

.Among the San Francisco architects
who have been exceptionally busy since
the beginning of the new year are Messrs.
Welsh and Carey. They have let con-
tracts aggregating more than $200.0(X) in
the last three months, and at the present
time are working on plans for a pic-
turesque private hotel at Stockton, a con-
vent at Livermore. an apartment hotel
and several smaller structures. This
firm made the plans for an apartment
house now under construction for the
Sheeby Estate, also a warehouse and a
church.

An Eastern contractor who has
had considerable experience in con-
crete construction,
has raised an inter-
esting point for the
architect and en-
gineer to decide. He
contends that it is the duty of the
man who designs a concrete build-
ing to conceive the form work as
well. Occasionally, just as he will
now design some especially import-
ant bridge falsework, the engineer
prepares form plans for some special
concrete structure, but, generally
speaking, the falsework is designed,
prepared and erected by the con-
tractor. This prevailing practice,
says Engineering and Contracting,
has come about perhaps from two
principal causes. The first is that
the engineer has conceived form
work as being solely temporary con-
struction plant like a staging for
brick work, and therefore a problem
which did not concern him beyond
the point of seeing that the objects
sought, namely, safetj^ and certainty
during construction and a completed
structure of acceptable quality and
character, were reasonably well as-
sured. The second cause has been
the great development, particularly
in reinforced concrete building work,
of engineering-contracting organi-
zations or firms which assume all
problems of design and construction
guaranteeing an acceptable product.
Incidentally, in the work of these
firms we do have examples and about
the only ones of form work con-
sidered as a definite part of the en-
gineer's designing problem. Else-
where as already stated it is con-
sidered usually as purely a contrac-
tor's construction problem. Whether
or not this is the logical viewpoint,
it is the prevailing one. Should it
remain so?

Form design is a problem which
without question, is worthy of the
best engineering talent. The prob-.
lem is not a simple one. It is not
merely in any specific case a prob-
lem of designing a structure which
will shape to dimensions and sup-



The Architect and Engine

port safely a certain volume and
weight of concrete. It is rather the
problem of designing a set of moulds
for repeated use in forming and sup-
porting successive similar units com-
posing a complete structure. This
involves much more than a mould
which will properly shape and safely
sustain one beam or bracket or col-
umn ; it involves the making of a
mould which can be erected, taken
down, moved and re-erected many
times, with the greatest speed and
the least labor, to shape and support
in succession a large number of
beams or brackets or columns. It
involves, too, not only the economic
use of material by careful design but
also economic consumption by de-
sign which will insure as high a sal-
vage value as may be. Forms are
not temporary structures in the
sense that staging or falsework are,
they are rather operating construc-
tion plant in almost the same sense
as is a concrete mixing and handling
plant.

Keeping in mind what has just
been said the question is : Is it bet^
ter that the engineer^ should design
form work or is it better that the
contractor should? The answer is
that it depends upon who the en-
gineer is and who the contractor is,
An engineer with an intimate knowl-
edge of construction work and costs
may easily be the best possible de-
signer of form work. On the other
hand an engineer lacking this special
knowledge may just as easily be
about the poorest one imaginable to
design form work. The extremes in
ability between contractors are al-
most as far apart. On the whole tha
contractor's training is more im-
portant to the task than is the en-
gineer's. The contractor may fall
short as compared with the engineer
in knowledge of statistics but the en-
gineer seldom has the contractor's
knowledge of practical operating
conditions and costs. Frankly, we
believe that on a cost basis the aver-
age contractor will prove a better



designer of form work than will the
average engineer. If this be so then
it is the better engineering practice
that the contractor should be the de-
signer.

This inquiry is heard on all sides.
With one year gone and but three

remaining, the an-
WHY IS EXPOSI= nouncement that the
TION WORK AT beginning of con-
A STANDSTILL? struction work will

be delayed until
October comes like a solar-plexus
blow to both commercial and build-
ing interests in San Francisco. The
contributors have paid their money
with the expectation that it would
be utilized, not hoarded. Large
numbers of mechanics have been at-
tracted to the city by the Exposition
announcements and these are idle
and in many cases without funds.
Other projected buildings are wait-
ing for the Exposition wheels to
start. When these move, then the
machinery will hum all along the
line. At present the money remains
without interest (or at least no in-
terest is shown in the credits on the
Exposition statements). Why keep
it tied up in a napkin when its use
would mean security for the Exposi-
tion and prosperity for San Fran-
cisco?

Then, too, from October, barely
two years will remain for a vast
amount of construction work. When
we consider, for instance, that one
small structure like the Hearst
building, began four years ago, is
not yet completed, is not the entire
Exposition jeopardized by further
postponement, especially in view of
possible delays on account of non-
arrival of materials, labor strikes,
etc. With our early start it was
hoped that the Panama-Pacific Ex-
position would offer an example of a
World's Fair that was complete
when the gates were opened and not
the usual complex, congested and
confused assortment of unfinished
buildings and incomplete exhibits.

similar manner. No automatic tempera-
ture control was installed, and none has
been found necessary. An even tempera-
ture of the water is attained by maintain-
ing a steady fire and regulating the flow of
water by hand.

As a matter of precaution against a leaky
pool the water pipes were installed so that
they do not pass through the waterproofing
of the wall of the pool below the water
line. This was accomplished by installing
the pipes horizontally under the floor of the
pool room and dropping branches to the
proper depth in the pool between the water-
proofing and the brick lining. All concealed
water pipes are brass ; other pipes are gal-
vanized iron.

The pool, which may be considered an
experiment, has been so satisfactory that
Mr. Coppell has ordered built a much
larger pool, 44 feet long by 26 feet wide,
with the addition to his house and the
equipment for the new pool has been de-
signed on the same principles as the one
described.

Ventilating Moving Picture Halls

A committee representing New York
Chapter of the American Society of Heating
and Ventilating Engineers reports the fol-
lowing recommendations for the compul-
sory ventilation of moving picture audito-
riums:

Floor Area Per Occupant. — A minimum
of S square feet of floor space per occupant,
exclusive of passageways, shall be provided
in the audience hall.



Cubic Space Per Occupant. — A minimum
of 90 cubic feet of air space per occupant
shall be provided in the audience hall.

Quantity of Outdoor Air. — A positive
supply of outdoor air from an uncontam-
inated source shall be provided the audience
hall at all times while the show place is
open to the public, and the quantity of this
positive supply of outdoor air shall be
based on a minimum requirement of 20
cubic feet per minute per occupant.

Temperature. — The temperature of the
air in the audience hall shall be maintained
throughout at the breathing line (persons
being seated) within the range of 65 de-
grees F. to 70 degrees F.. and the tempera-
ture, distribution and diffusion of the sup-
plied outdoor air shall be such as to main-
tain this result without uncomfortable
draughts.

Direct Heat Sources. — Any good heat
source which does not contaminate the air
will be accepted to supplement the warmed
outdoor air supply. Gas heaters or coal
