A steady increase in business has com-
pelled the Yager Sheet Metal Works of
1006 Seventh street, Oakland, to cast
about for larger quarters. Mr. Yager has
a desirable location in view and hopes to
move within a short time. During the
past two or three years this firm has
completed some of the most important
work in the sheet metal line undertaken
in the Trans-bay cities. Architects and
contractors like to deal with Mr. Yager
because his work is done well and there
are no delays.

One of the best of the more recent
jobs of galvanized iron completed by the
Yager Works is on the Central Bank
building at Fourteenth and Broadway,
Oakland, and the one-story store build-
ing at the corner of University and
Shattuck avenues, Berkeley, designed by
Architect John G. Howard. The galvan-
ized iron cornice and balustrade and the
copper front were put up by Mr. Yager.
A photograph of the building is shown
herewith.



McWhirter & Drake.

These well-known masonry contractors
have enjoyed an exceptionally good year
from a business standpoint and 1910 prom-
ises to be equally busy for them. Their
work has been high class in every instance.
They are members of the San Francisco
Builders' Exchange, 188 Jessie street,
and may be found there during the noon
hour each day or a letter addressed to
1329 H street will reach them. They are
prepared to give estimates promptly on
all kinds of masonry work.



Asbestos Protected Metal.

Tlie P. J. Knudsen Company are the
Pacific Coast agents for Asbestos Protected
Aletal, considered one of the best, safest
and most economical roofings on the mar-
ket today. Because of superior construc-
tion its manufacturers claim it will add 100
per cent to the safety and endurance of
any structure, whether factory, icehouse,
power plant, grain elevator, garage or resi-
dence. It is also unequalled for inter'or
work, making an attractive and pleasing
ceiling or wall finish. It takes paint per-
fectly, is absolutely fire and vermin proof
and sanitary. An illustrated catalogue will
be sent to any reader of this magazine on
application to the Pacific Coast agents, the
P. J. Knudsen Company, 310 California
street, San Francisco.



Builds Fine Homes.
Louis J. Larson, the well-known Oak-
land contractor and builder, was the con-
tractor of the handsome residence, an
interior of which is shown in the adver-
tisement of E. A. Howard & Co. in this
issue of the Architect and Engineer. A.

New Building Ordinances for Los
Angeles.

THE building ordinances of the city
of Los Angeles have been re-
drafted. One of the chief changes
made is the rearrangement of the exist-
ing ordinances, the various regulations
being put in better shape for compre-
hension by the layman.

Other changes have been made in reg-
ulations, however, which will have to
be taken into account by the designer
and builder. It had been recommended
by the Chief Inspector of Buildings that
a limit of height to four stories in other
than class "A" structures for hotels, apart-
ments and rooming houses, be incorpo-
rated in the new ordinance, but sufficient
pressure was brought upon the council
to have this changed to six stories.

The recodification was done with the
advice of a committee of architects con-
sisting of Octavius Morgan, J. P. Krem-
pel and A. R. Kelly. The following syn-
opsis, prepared by Chief Inspector of
Buildings J. J. Backus, will give some
general idea of the changes:

Section 2 has been changed to require
the seal of the building department to be
placed upon drawings showing they
have been approved by said departmeni.
This is in line with the general practice
in all large Eastern cities.

The sections relative to stairways in
buildings of classes "B" and "C" have
been changed to slightly increase the
number of stairways required in a given
area. These changes are made with a
view of safeguarding occupants of build-
ings. _

A section has been added providmg
for the erection of hollow tile buildings
outside of the fire limits with six-inch
walls, provided such buildings are not
over one story in height. This was done
with a view to giving the people an op-
portunity to obtain semi-fireproof build-
ings without going to the expense of
regular masonry walls.

A section has been added requiring
that all buildings erected hereafter to be
used for hotels, apartment houses and
rooming houses be constructed class "A"
where the building exceeds six storiei
in height. This change, also, was made
with a view to safeguarding the occu-
pants.

The fire escape section has been
changed requiring that where fire escape
ladders cross windows that such win-
dows shall be constructed of metal
frames, sash and wire glass. This is to
prevent fire from breaking through the
windows and cutting off the means of
escape from upper floors.

A new section has been added re-
quiring that all hospitals hereafter
erected, which are over one story in
height, be of fireproof construction.



Gravel and Sand

Our clean, fresh-water Gravel and Sand
has been tested and is specified by the
leading engineers of the State, and has
been used by contractors on some of the
largest buildings, bridges, and on oil
macadam, asphalt macadam and rein-
forced concrete macadam roads in this
Stati-.
Our Roofing Gravel is the only

material in this market perfectly adapted
to this work and is specified by the
leading architects and used e.sclusivelv by
the best roofing contractors.

A provision has been added to the or-
dinance requiring that in the erection ot
steel frame buildings there shall be con-
structed a temporary floor in order to
safeguard the \yorkmen erecting the
steel work; .said temporary floor to be
on the second story below the point at
which work is being carried on.

The ordinance herewith presented
makes no change in the reinforced con-
crete section, nor in the sections govern-
ing existing theaters and moving picture
houses.

In addition to the changes above
noted, there are a great many through-
out the ordinance, which are more or
less of a minor character and chiefly con-
sist of transpositions of sections and
phrases to make them read more intelli-
gently, the entire ordinance has been re-
vised from a legal standpoint with a
view to making it clearer and enabling
the Board of Public Works to prosecute
any one for violation of the ordinance.



Wide Concrete Bridge.

The City Commissioners of Hutchin-
son, Kansas, have decided to construct
a single, reinforced concrete arch, with a
50-foot span, over Cow Creek, at the
intersection of Main street and Avenue
"A."

City Engineer McLane reports that
it will be possible to span the creek
with a single arch, and a rise of six or
seven feet may be secured. The bridge
will cover the creek for a distance of
over 300 feet, with an area of approxi-
mately 16,000 square feet.

Engineer McLane will prepare plans
which, after approval by the Commis-
sioners, will be submitted to the con-
tractors for bids, and City Attorney Ty-
ler will prepare the necessary resolu-
tions or ordinances so that work may
be started in the spring.

This will be the first structure of the
kind in the city, and the commissioners
have, by their decision, fixed the policy



of replacing the twelve or fifteen wooden
bridges now spanning the creek with
permanent bridges, when renewal is re-
<|uired.

Metal Staiiifing ami Corrugaliiig Coiifaiiy.



Moves to Larger Quarters.

A constantly increasing business has
compelled the San Francisco Metal Stamp-
ing and Corrugating Company to seek
larger quarters and the company has been




us' Bear of Slu-cl Metal

fortunate in securing a satisfactory lease
of the property at the corner of Nineteenth
street and Treat avenue, opposite the Mis-
sion foundry, which will be the future home
of the industry, the change of location from
296 Eleventh street, having been effected
soon after the first of the new year. Ac-
cording to Manager Theophile La Haye,
the old location was outgrown six times
in two years, that is to say. the old place
was added to and added to until there was
no more space available. Tlie company
has been exceptionally successful in the



manufacture of stamped and spun sheet
metal ornaments, statue work and art metal
ceilings.

The new factory is 50 by 100 feet and
two stories. The ground floor is taken up
with the stamping, spinning and metal
drawing machinery, two new presses hav-
ing been purchased, also the rolling ma-
chinery and drawing bench. Upstairs are
the sample and store rooms and the offices
of the company. The illustration of the
Native Sons' bear, shown herewith, is an
example of tlie company's work in sheet
metal ornamentation. The bear would, in-
deed, make an appropriate decoration for
each and every Native Sons' building
erected in the Golden State.



New Branch Office.

Robert W. Hunt & Co., engineers,
have established an office in Mexico
City, at No. 20 San Francisco street,
and Mr. Carl Holt Smith, for many years
with the National Railways of Mexico,
has been appointed Mexican and Central
.American representative nf the firm.



Death of Mr. Paul Richter.

.Mr. Paul Richter, president of the Rich-
ter Manufacturing Company, of Tenafly,
N. J., died at his home in Tenafly on De-
cemlier 6th.

African Mahogany in the San Francisco
Market.

White Brothers, the San Francisco
hardwood lumber dealers, have shipped
from their mill at Petaluma a large
stock of the species of African mahog-
any known as Gaboon. The logs from
which this lumber was manufactured
were so large that White Brothers were
enabled to saw up all clear lumber.
Gaboon is a kind of mahogany which is
little, if at all, known in this market. It
is a little lighter in color than the Mexi-
can or Honduras wood, but has the same
grain with the exception that it is more
liighly figured. Practically all the boards
have a wavy grain. Fink & Schindler,
the interior fixture firm of San Fran-
cisco, have finished up some of this
African mahogany or Gaboon and pro-
nounce it excellent, especially for a
lighter finish than ordinary mahogany.



An Enterprising Industry.

One of the newcomers in the building
field in Alameda County is Cooper's
Floor Company of Berkeley, which
makes a specialty of hard-wood floors.

The firm also sells finish material, and
carries a complete line of wax-filler, ben-
zine, oil, weighted brushes and castors.

Mr. F. E. Cooper was employed in the
hardwood floor business in Oakland for
three years. Last October he established
the present firm, of which he is the man-
aging partner.

Cooper's Floor Company, though
young in the field, has already taken
more than fifty contracts, among which
is the residence of Mr. P. E. Bowles, the
banker. This residence was built by
Kidder & McCullogh, and there are four
thousand square feet of hardwood floor-
ing in the house.



Change of Name and Address.

The Watson Roof Company, contract-
ors for the preparation and application
of "Wafsonite" flooring, and felt and
gravel roofers, have changed their name
to Watson Floor and Roof Company,
and are now located at 932 Folsom
street, where a mixing plant is in course
of construction. No change has been
made in the personnel of the company.

Among the recent contracts for "Wat-
sonite" flooring are: Anglo and Lon-
don-Paris National Bank roof; Union
Trust Company, new building roof; new
almshouse, two connecting corridors ;
Mercantile Trust Company, roof to new
addition; stable for Dr. Bricca; stable
for W. & J. Sloane Company, stable of
National Ice and Cold Storage Com-
pany.

Test of the Lindley Oil Burner.

One of the practical inventions of the
20th century is the adaptation of o-l
burners to the use of residences, as well
as to manufacturing plants. There have
been several burners invented, each of
them more or less an advance over those
that came before.

The Lindley Oil Burner, which has
been on the market in Los Angeles for
three years, seems to have attained pret-
ty near the perfection point, and is in
general use in the southern city. The
company has recently established an
agency in Oakland, Long & Long being
the northern agents.

As proof of the practicability of their
system, the report of Mr. John Wicks,
inspector for the Home Telephone Com-
pany, in whose Oakland headquarters
the Lindley Burner was recently installed
is given herewith:

pany, old burner:
