32 THE CONCRETE AGE ( h 'TOBER, 1920, A. r XX ! THE ONLY SCREW HOLES IN THE WORLD a § You drive the screw holes with a hammer in any material. The screw holes are made for wood screws or machine screws to fit all sizes of screws. The head is removed and you leave a permanent screw hole. The Stine Screw Holes Co. Some of the Reasons Why Screw Holes Will Be Bought and Used and Not Become Dead Stock for Anyone. 1— They can be used without damage to receiving material. 2They enable you to standardize to wood or machine screws in all material. 3They are made of brass and will not rust undt atmospheric or moisture conditions. 4 ECONOMY—They save more time value than the holes cost. 5You get them for nothing and are paid for using them when you count time saved. 6Screw holes have been needed ever since the first screw was used. 7Special tools are NOT needed in using them in any material. 8 They can be used in any place a screw can be used. 9 —By using screw holes, screws can be used in many places, and in many materials where it is impossible to use screws without them. 10—These are the only ready-made screw holes in the world. 11 — No special screws are needed. These screw holes fit any wood screw or machine screw now in stock. 12—They make the neatest possible job in any material. 13—Every store where screws are sold must carry them in stock, because the line of screws is not complete without screw holes for them. 14—Every shop and factory where screws are used must also have these screw holes to fit the screws. 15—They are endorsed by all dealers in screws and by all users of screws. 16—Screw holes are entirely new and the world supply is yet to be furnished. 17— This is a progressive Old World of ours, and every active person in it must adopt all improved methods, and all new articles that will help him keep in the front line of progress. 18— Be among the first to stock up in screw holes if you are a dealer in screws. 19 Be among the first to install screw holes in your shop or factory, as you begin to save money soon as you use them. 20— In spite of the high cost of brass, screw holes are yet cheap. 21— We are letting the world know that screw holes can now be secured, by means of extensive advertising in all the principal Trade Journals that have the largest circulation among dealers in screws as well as users of screws. 22Do not let your customer ask you for screw holes before you have them in stock. BE A LIVE WIRE. 23 They make everlasting holes in any material. 24 They mean “Plug-No-More” screw holes. 25 They are the result of Necessity being The Mother of Invention. 26 Anyone who can drive a nail can use screw holes. 27 Send for a sample and convince yourself. 28—Mechanics who see them say, “What do you think of that?” 29 In fact there are NO REASONS why screw holes should NOT be used. Each of these reasons is enough to sell S:rew Holes. There are many other reasons.

How’s the Weather —and the Roads?

One would scarcely look for an editorial on roads in the daily Forecast Bulletin of the United States Weather Bureau, especially an editorial promoting permanent highways— yet you'll find one there from time to time just the same.

In the bulletin issued February 6 by the Lansing, Michigan, branch of the United States Weather Bureau, the condition of the highways as affected by the weather, formed the sum total of the report.

A portion of a paragraph from this report reads as follows:

‘ ‘OUT OF DETROIT : Roads in Wayne County are cleared and in good condition. ****’’

It will be remembered that Wayne County has nearly 200 miles of concrete roads.

Nnpaved roads vary with the weather—paved roads are constant. When the weather is good, dirt roads may be passable if they have been continuously dragged, but they are no roads for truck and outomobile traffic, so characteristic of the highways today.

The Highway Weather bulletin is an important and useful contribution from the Department of Agriculture, mads doubly so by recognition of the fact that the state of the roads is more important than the weather, and that you needn’t worry about the weather if the roads are paved.

War Trucks for Road Builders

One month ago the War Department had turned over to the United States Department of Agriculture approximately 24,000 motor vehicles, as provided in congressional legislation empowering the latter department to distribute this war material among the State highway commissioners for use in road building, allotments of the vehicles to be based on the amount of Federal aid for roads which the States receive. This is practically all the vehicles which the War Department has to release. If this total 12,000 have been delivered to the State. The remainder will be distributed as fast as railway cars can be secured for their transportation. Representatives of the Bureau of Public Roads, in charge of the matter, believe that within two or three months

8 THE CONCRETE AGE APRIL, 1920

all of the vehicles will have been delivered to the States. This equipment promises to be a great aid in. carrying out the large road building program for 1920.

The State highway commissioners are also interested in securing allotments of tractors, steam shovels, locomotive cranes, automotive cranes, industrial railway track, dump cars, and industrial locomotives which remain to be disposed of by the War Department. A measure known as the Kahn Bill, directing the Secretary of War to release this material for the State highway commissioners, has passed the Senate and has been reported out of committee in the House. Until the Secretary of War has been directed by Congress to turn over this equipment it is not likely that it will be available for State distribution.

Model Village for Asphalt Works

Plans have been completed by the New Trinidad Lake Asphalt Co. at Brighton, West Indies, for a model village for its own workmen and those of associated oil companies and construction work is to be started immediately.

The new village will be located on the company’s property near the asphalt lake, and will be laid out with all modern conveniences, including streets, waterworks, sanitary sewerage, and electric lighting. Houses for families will be located in one portion of the village, and each house will have a fenced yard where the family can have a kitchen garden. Separate houses with a parcel of land around each house will also be provided for the foremen. The barracks for single men will be built along sanitary linefc and will be equipped with showers. Separate apartments, with kitchens, will be built for small families or married men without children.

The houses first constructed will be occupied by the permanent employees of the company, but it is contemplated to construct quarters sufficient to house also casual workmen who may be given employment by the company.

The present system of allotting from one-half to one acre of land for a garden to those who desire to cultivate a plot of ground will be continued.

Concrete Tenement Houses for Milan, Italy.

Consul Winship reports from Milan, Italy, that in order to relieve the housing situation in that city plans for the construction of about 1,000 concrete tenement houses in addition to those under construction have been prepared. These will be built on a cottage type in separate buildings, accommodatingfour families each, in all about 5,000 persons, and occupying an area of about 400,000 square meters.

Engineering Feat 2,000 Years Old.

The Chengtu irrigation system is one of the most noteworthy examples of an early engineering feat and deserves to rank with the Pyramids. The head waters of the system are in the foothills of the Tibertan Mountains at the city of Kwan Hsien, where the Fu Kiang breaks through the northern part of the plain and makes its mad rush toward the sea. The river bed falls in level 1.200 feet during its seventymile trip along the edge of the plain. Some idea of the magnitude of the engineering task may be realized from the fact that the flow during a freshet is not far from 30.000,000 cubic feet of water a minute, approximately the flow of the Niagara River.

The irrigating water is taken from the main river just before a gap in the hills is reached and is conducted by an artificial river through a gorge cut in the mountain side. After passing the mountain barrier the artificial river is divided into three main branches which in turn are subdivided again until an irrigation ditch serves every acre of the plain. The regulation of the flow of water into the irrigation ditches is one of the most ingenious parts of the plan. First, the cut in the hill was made just wide enough so that the volume of water entering when the gauge stood at a predetermined level would fill without overflowing the ditches everywhere over the plain. A flood due to overflowing of the ditches is a rare occurrence. Second, to prevent the water from rising higher than the gauge, the artificial river is provided with by-passes before it reaches the gorge. These by-passes allow all the excess water that cannot enter the gorge to flow back into the main river. This entire section of the artificial river has banks flanked with bamboo, filled with stones— masonry and various permanent banks have been tried but given up in favor of the bamboo baskets, replaced every year during the dry season. —H. K. Richardson, in Asia.

Report of Committee on Resolutions National Conference on Concrete House Construction

The United States and Canada are now confronted with an unprecedented housing famine, so universally recognized as to need no emphasis. This originated in governmental allocation of labor, materials and capital to war needs, and has been confined and accentuated by the diversion of labor, materials and capital to the production of nonessentials. To such an extent is this true that the public demand for these non-essentials and even for luxuries, is raising the cost of housing, while the people are bidding against each other for the houses which exist.

The effect of this housing shortage is not merely to inflict hardships on the people, but to excite to higher pitch those feelings of discontent so widespread in the country since the war.

We deem it our plain duty as citizens to offer to our countrymen such advice as our professional and trade experiences qualify us to give, as to the best methods by which the problems may be solved and normal conditions restored. Only by an analysis of the factors entering into house building can we hope to arrive at an understanding of either the problem or its remedy.

Before entering on this analysis, reference must be made to the effect of the depreciation of the dollar which hangs like a cloud over the whole business horizon. To the mass of people this is still a mysterious phenomenon. It began before the war, due to great increase in gold production, and has, of course, been intensified by the inflation of the currency. While the people at large are thinking in terms of high prices they would be nearer the truth if they were thinking of lowered standards of value. The public view of this matter cannot soon be altered and we must, therefore, treat it for the present as an established fact.

The main factors with which we have to deal are more numerous than is the general belief; they involve among others, Land, Materials, Labor Finance, Transportation, Design, Legislation and Building Ordinances. Clearly relief can come only through the construction of mere houses of the right type. All building is for a profit in some form. Unless profit can be reasonably assured in residence construction the building of homes will be limited to prospective owners who are but a small fraction of the population of large communities. Houses must be provided for the great mass who can only afford to rent or to buy on long term installments.

If, as will be generally conceded, after food sup ply, houses are the most fundamental need of the people, housing supply should take precedence over all other use to which capital can be put, and that we are justified in urging that all possible steps be taken to make investment of private capital in house construction more attractive than any other form of investment. Investment can be encouraged but cannot be forced.

Private initiative has in the past always been found competent to solve the problems of the country, and with proper encouragement and incentive can be relied upon to successfully grapple with the present emergency. Federal governmental methods, even with the utmost efficiency of direction and handling, are slow, cumbersome and costly. Experience seems to show that every dollar which government puts into a competitive business, drives out $10 of private capital.

In most of the States constitutional obstacles defer the possibility of help from these sources for, at least two years. Prudence, therefore, dictates that the hope of such aid even were it desirable must be discarded from our calculations. What State governments can do, however, is to remove the obstacles which, in the form of taxation, they now place in the way of constructing new buildings.

Since the housing scarcity is the result of governmental restrictions and taxation, preferential allocation of materials and cars and governmental exemptions must be enlisted to restore normal conditions.

Land.

Taking up the related factors, we may say in general that price and availability of land at present are such as held at low figures because of the difficulty which its owners find in putting it to profitable use. This condition in reality should act as a stimulus to building.

Materials.

The widest latitude in the use of approved materials should be encouraged. Especially should this be emphasized for the purpose of relieving transportation congestion and the lowering of building costs. Because numerous sources of supply can generally be drawn upon, concrete is one of the most readily procurable building materials.

There is now a famine of houses. There is also a heavy demand for building maerials for other and less important uses. Materials needed for home construction shou'd be given preferred consideration in manufacture and distribution. Manufacturers of such materials should give priority in shipment when intended for this purpose, as opposed to other uses less

12 THE CONCRETE AGE April, 1920.

Reserve System, money, during the past few years, has been drawn away from long term investments in favor of short term loans, with the result that, while savings in the United States are estimated to have increased 200 per cent from 1913 to 1918, and the total loans and discounts of banking increased 54 per cent, the combined real estate loans of banks and insurance companies and building and loan associations increased only 28 per cent in the same period.

In view of these facts, it -appears necessary that this hitherto neglected portion of our banking system should be taken care of through adequate legislation.

One of the chief problems encountered is lack of funds to finance home building. It is desirable in the public interest that the funds now tied up in first mortgages held by the building and loan associations be made available for dwelling house construction and that the “Federal Building Loan Act,'' Bills S. 2492 and H. R. 7597 entitled “A Bill to Encourage Home Ownership and to Stimulate the Buying and Building of Homes; to Create a Standard Form of Investment Based on Building Association Mortgages; to Create Government Depositories and Financial Agents for the United States; to Furnish a Market for Government Bonds; and for Other Purposes,” be endorsed by this Conference.

Much money hitherto invested in first mortgages on dwelling houses is being diverted to non-taxable investment channels. It is desirable that exemption from income tax be granted to such investments. Bills S. 2094 and H. R. 8080, entitled “A Bill to Encourage the Building of Homes by Providing for the Exemption from Taxation of the Income from Mortgages on Real Estate’’ should be endorsed by this Conference; and we urge that members of this Conference write to their Senators and Congressmen, and endeavor to have others do likewise, urging them to support and favor the prompt enactment of these bills. There is now proposed an amendment to the Federal Reserve Act requiring that National banks maintaining savings departments shall invest all savings deposits in such forms of securities as may be directed by the Federal Reserve Board. Since the object of the proposed amendment is the adequate protection of the interests of depositors, and since its effect will be the diversion of more than two billion of dollars, now held in savings accounts, from short term loans to long term investment in construction enterprise—- a sum equal to the present combined assets of the building and loan associations of the United States—- the enactment of this measure is recommended.

Recognizing the fact that the building and loan associations of America are an important factor in financing home building and home ownership, and that these institutions confine their activities to teaching thrift and financing home ownership, we urge all organizations and individuals interested in promoting the construction of homes to affiliate ad cooperate with building and loan associations in their localities and to assist in forming such associations where they do not now exist.

As the most difficult financial obstacle to the construction of homes is that of filling the gap between the amount obtainable on first mortgages and the amount the purchaser is able to invest, this Conference commends the work of community housing corporations and employers of labor who are using their own funds or credit to relieve the urgency of the present housing shortage.

Design.

To secure results that will satisfactorily meet present housing needs, safety and economy in the construction of homes mu ;t be recognized as of paramount importance. These materials applied by the best talent in design and construction.

It is, therefore, recommended that the organizations and individuals cooperating in the National Conference on Concrete House Construction enlist the cooperation of others not yet identified with the Conference to work with them in securing designs and specifications for small houses, that will give proper recognition to the numerous advantages of concrete in its possible forms of application, and in this way help to increase and perpetuate the value of this Conference.

In order that these data may be made available to all who wish to design, build or buy a home, we recommend the institution of a National Competetion, with judges of such recognized standing as to inspire confidence necessary to enlisting best efforts of which contestants are capable, with prizes in number and value to attract such talent.

As an aid to the furtherance of this idea it is recommended that all interestedsubmit data on every method by which concrete can be applied in the construction of houses, to enable intelligent selection and application of the best in design and specifications. The conditons of the competition should be made sufficiently broad to secure the support of engineers, practical builders or any others who have developed safe and economical systems of wall, floor and roof construction or any devices that will make houses moie comfortable as a shelter, more attractive and cheerful as homes, and stimulate incentive to build houses for investment. Economy in erection, low cost of maintenance, reduction of fire risk and cost of insurnce should anticipate the use of fire resisting materials wherever practical.

It is further recommended that a Bureau or Committee of Information and Research be established to devise, promote and educate along lines conducive to more extensive use of concrete and the advancement of concrete design in home building.
