$1,041.62 on January 12, 1913, to $2,823.20 for the year just ending.

The report of the council stated that all of the proposed amendments recently submitted to the membership by the council had been adopted. One of the most important of these amendments is one providing for the holding of the professional sessions of the annual meeting outside of New York City, if desired.

President H. M. Hart of the Illinois Chapter read the report of that chapter calling special attention to the success of the plan adopted at the meetings of the chapter of having the subjects taken up in the form of a debate with a certain number of speakers chosen to represent each side of the question. No decisions. were rendered, he said, so that no particular systems of heating were endorsed.

The New York Chapter report was read by Secretary Scott and covered the work of the chapter during the past year. The subjects for the remaining meetings of the chapter for the season of 19131914 were given as follows:

February meeting: Fan selection. March meeting: Schoolhouse heating and ventilation.

April meeting: Hot water heating.

Following the chapter reports, the committee on standards presented the code it has formulated for testing house heating boilers. This is given in full on another page of this issue. In connection with the report, Mr. Donnelly moved for the appointment of a committee of five to develop a standard specification for a house heating boiler and, to this end, to confer with the master steam fitters association, architects and engineers generally. This motion was carried.

HEATING GUARANTEE CLAUSE ADOPTED.

The Committee on Heating Guarantees, through W. M. Mackay, chairman, presented its recommendations of last year to the effect that the designer of apparatus should be considered responsible for the results to be obtained by its use, provided it is installed and operated as designed and intended; and that the contractor should only be held responsible for the installation of the apparatus in the time agreed with material specified, in exact conformity with the design and

specification, and such materials and labor as he may furnish in placing the apparatus, and that any guarantee which the contractor may be called upon to give, covering the installation, completion and materials and labor furnished, should not extend for a longer period than one year from the time of completion and permanent operation of the apparatus.

The committee recommended that this clause be expressed in legal phraseology for use as a part of specifications for This heating and ventilating systems. was put to a vote and carried.

President Hale appointed as tellers of election R. B. Hunt, New York, chairman; E. K. Munroe, Baltimore, Md., and A. A. Kieb, New York.

THE NEW NOMINATING COMMITTEE.

The following were elected as the nominating committee for next year's officers: Frank K. Chew, New York; C. F. Newport, Chicago; P. H. Seward, New York; J. I. Lyle, New York, and John D. Cassell, Philadelphia, Pa.

Evening Session, January 20.

The evening session was opened by the presentation of a report on the work of Ventilation Division of the Chicago Health Department by E. Vernon Hill, M.D. Dr. Hill gave details of the many air tests made by the department in theatres and in street cars showing the improved conditions from a bacteria standpoint, that obtained in well-ventilated theatres. In the case of street cars, notably high dust counts were made in air taken in at or near the floor.

At this point the announcement was made by the tellers of the election of the following officers:

THE NEW OFFICERS.

President, Samuel R. Lewis, Chicago. First Vice-President, Edmund F.

Capron, Chicago.

Second Vice-President, D. D. Kimball, New York.

Treasurer, James A. Donnelly, New York.

Managers, Samuel R. Lewis, Edmund F. Capron, D. D. Kimball, James A. Donnelly, John F. Hale, John R. Allen, W. W. Macon, Frank T. Chapman, J. M. Stannard, Frank G. McCann, Frank Irving Cooper and H. M. Hart.

Following the announcement of the result of the election, a report was presented of the committee on legislation for compulsory ventilation. This consisted of a model ventilation law covering such buildings as schools, auditoriums, hospitals, theatres, moving picture shows and similar meeting places. This report was not given out for publication, as it will no doubt undergo further revision as a result of the suggestions brought out in the discussion.

The balance of the evening session was given over to a display of moving pictures illustrating the manufacture of pipe from the ore to the finished product. The pictures were described by Mr. Rowland, of the National Tube Company, and the slides shown were largely of views taken at this company's plant. The operations were shown in logical order beginning with the mining of the iron ore in the Superior district, followed by its shipment in vessels, including the methods for loading and unloading these specially designed ore boats. Its passage to the blast furnaces was portrayed and the pictures then took up the methods of manufacturing butt-weld and lap-weld pipe, including the Spellerized process. views and lecture were highly enjoyed by those present and added greatly to the interest of the meeting.

Morning Session, January 21.

The extra session called for Wednesday morning to discuss the proposed model compulsory ventilation law prepared by the compulsory legislation committee developed the fact that a considerable difference of opinion existed as to whether the society should specify the requirements only or should take up the question of methods of arranging the apparatus to fulfill the requirements. A report presented by Theodore Weinshank, chairman of the Indiana sub-committee on compulsory ventilation, advocated a code of methods which, he stated, were those comprised in a set of regulations used in Indiana which were expected to become a law within a month.

As a result of the discussion a committee of five members, consisting of S. R. Lewis, chairman: F. I. Cooper, F. L. Busey, J. D. Cassell and V. P. Hill was appointed to take up certain phases of the subject and report at a later session.

This committee handed in a report just previous to the final adjournment in which it expressed its agreement on the following points:

COMMITTEE RECOMMENDATIONS.

A positive minimum supply of outdoor air from an uncontaminated source of 30. cu. ft. per minute per occupant.

A minimum of 15 sq. ft. of floor area per occupant.

A minimum of 180 cu. ft. of space per occupant.

Temperature to be maintained at the breathing line within a range of 65 to 68 degrees Fahr.

Where relative humidity is under control it should be maintained between 40 and 50 per cent. The committee stated that it considered the elimination of dust as of special importance.

As to floor area per occupant in audience halls, a minimum of 4 1-3 sq. ft. per Occupant was advocated, exclusive of aisles and public passageways; also a minimum of 80 cu. ft. of air space per occupant.

Under the heading of "Quantity of Outdoor Air," it was recommended that a minimum positive supply of outdoor from an uncontaminated source should be provided in the audience hall at all times while the show places are open to the public, and the quantity of this positive supply of outdoor air shall be based upon a minimum requirement of 1,200 cu. ft. of air per occupant per hour where the so-called diffusion method (downward ventilation) is used. Where the so-called displacement method (upward ventilation) is used, a minimum of 1,000 cu. ft. of air per occupant per hour shall be supplied.

Under "Temperature" the recommendations were that the temperature of the air in the audience hall shall at all times, while the show place is open to the public, be maintained throughout at the breathing line (persons being seated) within a range of 62 to 70 degrees Fahr. (except when the outside temperature is sufficiently high not to require the air supply for ventilation to be heated). The temperature, distribution and diffusion of the supplied outdoor air shall be such as to maintain the temperature requirement. without uncomfortable drafts.

The committee stated that it would make recommendations regarding hospitals and factories and would forward them to the general committee.

Afternoon Session, January 21.

Two papers by A. M. Feldman of New York were presented at the opening of the afternoon session, one on "Cooling Two Rooms in a Country Residence" and the other on "A Ward Cooling Plant in a Hospital."

In the discussion of these papers Dr. Levy of Mt. Sinai Hospital, New York, spoke of the advantages of the treatment of sickness by cold air. He said that beneficial results in this direction have been secured on a large scale in the Philippines. In the treatment of typhoid fever a current of cold air blown over the patient was found better than drugs in reducing the temperature. Dr. Levy said the heating engineers had it in their power to do a work in connection with the reduction of infant mortality through the cooling of the air, that would compare with the boon of pasteurized milk.

Dr. C. E. A. Winslow, chairman of the New York State Ventilation Commission, said that he believed the time would come when there would be cool day and night nurseries located at given points in cities. He cited the papers just presented as evidence of the practicability of cooling the air on a wider scale in homes and hospitals. He also stated that he believed when the sanitarians finally decided on the requirements from a good air standpoint, it will be perfectly simple for the heating engineer to fulfill them.

At this point a report of the committee on standards on "Standardization of the Use of the Pitot Tube," was presented by J. I. Lyle, chairman. This report was accepted by the society as providing definite directions for using the Pitot tube in measuring air velocities through registers.

A paper was then read on "Coefficient of Heat Transmission in a Pressed Steel Radiator," by Professor John R. Allen. The paper contains a comparison of results secured with a cast-iron and a sheet metal radiator of the pressed steel type. In the absence of Prof. Allen, the paper was read by W. F. Verner of

The report of the activities of the Massachusetts Chapter were contained in a report read at this session.

The report stated that the chapter had been active in securing a revision of the Massachusetts laws dealing with the heating and ventilation of buildings used for public purposes. The new law has been signed by the Governor and took effect November 1, 1913. However, the chapter does not endorse the interpretation of this law as made by the Massachusetts District Police Inspection Department as to the ventilation of theatres, halls, and places of public gathering. because the law states that "the ventilation in all cases shall be taken off from near the floor level." The new laws and regulations are issued in booklet form and can be obtained upon application. The new regulations dealing with school house construction have yet to be issued, but it is understood that they are on the press. A new State law has also been passed and signed dealing with moving picture booths.

The chapter has also been active in securing new members for the society and no less than eight persons accepted for membership have been nominated by this chapter, a total of over 50% of the chapter's own enrollment.

The report concluded with the statement that the first school in the world for public health officials has been opened by Harvard University this winter under the direction of Dr. Milton J. Rosenau.

This was followed by a report of the representative of the society who attended the International Congress on School Hygiene.

For the committee on schoolhouse ventilation, Frank Irving Cooper stated that extensive experiments in connection with schoolhouse ventilation were under way. At the Massachusetts Institute of Technology the physical properties of the atmosphere were under investigation. The series of experiments on air washers, which were carried on at Harvard and Springfield during the past year, are being continued and additional tests are being made on ozone machines in connection with air purification.

As there was still some time left before the close of the session, one of the papers scheduled for the following day
