INETEEN TWENTY-SIX is to last year, according to an extensive sur- vey among architects and builders, con- ducted by The Architectural Forum, of New York. The method used included the obtaining of confidential reports from thousands of sources, covering six geographical divisions of the country in nineteen building classifications. These reports were tabulated and correlated and the totals determined by a system of weighting. Thus the final forecast figures were established after months of The accuracy of previous reports of the same nature issued, during the past five years, by The Architectural Forum, has given to these surveys an authority throughout the building industry. In view of the fact that the Forum forecast for 1926 indicates another six billion dollar building year, probably briefly the building activity of the year 1925 in order that later comparisons may be clear. As this article goes to press, the figures for the year 1925 in- dicate that approximately 62 billion dollars were spent last year for new At the beginning of the year 1925 all conditions indicated that that year would probably equal 1924, which estab- lished a record up to that time; but no one anticipated completely the amazing volume to which the building totals have climbed. Records were broken everywhere during 1925, as will be seen by an examination of Fig. 1, which shows the total value and volume of new building in 1925 as compared with each year since 1920, and also indicates the trend of building costs, commodity PROBABLE BUILDING TOTAL FOR 1926 The accompanying table indicates the tion shows the amazing total of $5,584,- of architects and into actual construc- 1913 BASE New officers of the Pittsburgh chapter, A letter from the Kansas City Chapter, containing the resolutions adopted by that chapter, was read. After some dis- Thus it is predicted that 1926 will be another six billion dollar building year, with certain changes in the relative proportions of activity in building types and districts. There will be approximately the same relative building activity in each of the six geographical divisions of the United States during 1926 as compared with 1925 with some decrease in the Northeastern and Middle States and a considerable increase in the Southeastern States (due to activity in Florida). The probable "normal" building year of today is four billion dollars or more and on this basis it would take three or four six billion dollar years to meet the still-existing shortage! All is well with the building industry. It is going about its business seriously, contributing to the wealth and comfort of the nation. Some idea of the magni tude and importance of the construction industry may be gained from a statement recently made by Secretary of Labor Davis in which he said: "More than 11,000,000 of our people are dependent for their living upon the construction industry, and 22% of all the skilled and unskilled labor of the country is engaged in the building branch alone. Some 250,000 freight cars are required to handle the materials. Our building bill is $200 per year for each family in the United States. It is truly the chief barometer of the business of the country.

Kimball, Ο New York's Fourth Power Show VER 400 exhibitors, of whom 73 were manufacturers of apparatus and appliances used in heating and ventilating work, was the record made at the Fourth National Exposition of Power and Mechanical Engineers, now known as the Power Show, held at the Grand Central Palace, New York, November 30 to December 5. This number represents an increase of 130 over last year's total of exhibitors. The attendance increased at an even higher rate, jumping from 47,000 in 1924, to 100,000 last year. Among the lectures given, during the Power Show, in the Conference Room of the exposition hall, was one on "Recent Developments in Heating and Ventilating," by President Samuel E. Dibble, of the American Society of Heating and Ventilating Engineers. Recent Developments in Heating and Ventilation Professor Dibble divided his address into two sections, the first dealing with heating and ventilation as a mechanical device for efficiency and economy of operation, and the second, with heating and ventilation as a mechanical device for the promotion of health. STATUS OF BOILER RATING On the subject of heating boilers and the progress made in their commercial rating by the American Society of Heating and Ventilating Engineers and the Heating and Piping Contractors' National Association, Professor Dibble said: "Heating boilers of the cast-iron lowpressure type have been greatly improved, and I believe will be still further improved within the next five years. With the development of the A.S.H. & V.E. Heating and Ventilating Code, and the adoption by the boiler manufacturers of their Low-Pressure Boiler Testing Code, all cast-iron boilers are now tested for over-all efficiency. There has been some valuable work done by the Heating and Piping Contractors' National Association in its attempt to give a commercial rating to all low-pressure cast-iron boilers after they have been tested in accordance with the A.S.H. & V.E. Boiler Testing Code. EDUCATION OF PUBLIC NEGLECTED ON ENGINEERING SUBJECTS "In the heating and ventilating industry, however, we have sadly neglected one very important point, and this is typical of the entire engineering group of industries. We have highly developed our industry, and among ourselves we are thoroughly convinced and we know whereof we speak when we state that a building can be heated and ventilated according to a predetermined condition. Where we have fallen down is in the education of those who are to occupy the buildings and others. We put in a heating and ventilating system, and then we issue orders that no windows in the building shall be opened. To my mind, this is a challenge for everyone to ignore the order and open the windows at the first opportunity. We issue orders upon the completion of our heating and ventilating job that no valves and no part of the mechanism must in any way be touched. This again is a challenge for the people who receive the orders to operate the valves and the levers upon the first opportunity presented. In my mind, it would be much better if we, as an industry, instead of giving orders what not to do, would give out information stating exactly what to do and how the heating and ventilating system functions, and what it will do when it functions properly. "The time is not far distant when city homes at least will be fitted with equipment furnishing properly-filtered, properly-humidified, and properly-heated air. During the past year it has been brought to my attention very forcibly by a system which I designed for a private home, in which all the air that entered the home was cleaned by means of dry air cleaners, was humidified properly by means of a humidifying device, was heated by means of indirect radiation, and air was distributed into the rooms by means of a fan and exhausted from the rooms by means of a series of ducts. "The operation of such an equipment is not very expensive and it is not beyond our vision to expect that this industry will provide means for cleaning all the air which is discharged into buildings for ventilating purposes. "In fact, if we let our imagination play for a minute, we might even suggest that all the air that we breathe will in a short time be cleaned and "These two organizations are bending every effort to assist one another in this enterprise, and it is hoped that before long every boiler manufactured in the United States will be tested in accordance with the recognized code, and will be rated in accordance with the recognized method of rating, thus giving uni- freed from all outside contamination. form results and information to the contractor and owner which will enable them to successfully select a low-pressure boiler for a given job." What seemed impossible years ago in the cleaning, the filtering, and the purification of all the water consumed in large cities, is to-day accepted as a com mon and simple undertaking, so much so that we will even water our streets and water our lawns and gardens with water which has been treated and made pure. Why is it not just as possible to conceive of having all the air we breathe cleaned in a similar way, and thus eliminate sickness and death caused by improper and unhealthy air?"
