ASSISTANCE OF CENTRAL STATISTICAL BOARD TO BUREAU OF MINES

Mr. Scrugham. Now, I would like to ask Mr. Furness some questions.

You are chief of the so-called Statistical and Economics Branch, are you not?

Mr. FURNESS. Correct.
Mr. SCRUGHAM. What subdivisions are in your organization?

Mr. FURNESS. It is subdivided into six divisions: Coal Economics Division; Petroleum Economics Division; Mineral Production and Economics Division; Metal Economics Division; Nonmetal Economics Division; Foreign Minerals Division.

Mr. Rich. Can you advise me what aid and assistance the Bureau of Mines receives from the Central Statistical Board in compiling data that is valuable to your branch of the service?

Mr. FURNESS. I think that the main service that the Central Statistical Board renders to the Bureau is to indicate to the Bureau where there has been a duplication or where there is a duplication in statistics. They also render to us a service in this way, that when we get out our annual questionnaires, we submit them to the Central Statistical Board for criticism and advice, which we may or we may not follow.

Mr. Rich. If they tell you that the information or data that you are trying to find has been secured by some other branch of the Government, do you accept their recommendation to use that?

Mr. FURNESS. Yes; we accept it, and we attempt then to cooperate with the agency that is collecting that information, because sometimes we find that it is not a direct duplication. In other words, they will not be collecting all that we need, so that it is not a complete duplication.

Mr. Rich. But if they show you that you can get this information in other departments, you accept their advice?

Mr. FURNESS. Correct.

Mr. Rich. Have they been of any assistance to you in cutting down the expense of your Department because of the information that they have furnished you?

Mr. FURNESS. I could not say so, tangibly. Intangibly that is possible. I could not lay my finger on any item and say that they have saved us that much money.

Mr. Rich. Have they rendered you any service?
Mr. FURNESS. As I have said, I think so.

Mr. Rich. If they would notify you where you could get the data that you were trying to secure, would that not be an economy in your Department?

Mr. FURNESS. Absolutely.

Mr. Rich. That is what I am trying to get at, whether the Central Statistical Board has been of any value to you in that respect, in cutting down your own expenses.

Mr. FURNESS. I could not put my finger on anything tangible. I would say theoretically, yes, but tangibly, no.

Mr. SCRUGHAM. Mr. Furness, in the Division of Foreign Minerals, do you in any way duplicate the work that the State Department, through its consular service, is doing, or the work that the Bureau of Foreign and Domestic Commerce in the Department of Commerce is doing?

Mr. FU'RNESS. I would say in part, yes; but broadly, no. Mr. SCRIGHAM. Mr. Furness, the Guffey-l'inson coal bill organization is proposing to ask for approximately $1,000,000 for their organization which is to be devoted almost entirely to coal economics, and I think that a very careful study will have to be made to prevent an overlapping of functions.

That is all. Thank you.

FT NCTIONS OF THE MINING DIVISION
Next is Mr. C. F. Jackson, Chief of the Mining Division.

What are the functions, Mr. Jackson, of the Mining Division of the Bureau of Mines? What is its importance to the national welfare?

Mr. Jackson. Broadly, its services are designed to improve methods and practices in mining and promote conservation of our mineral resources. This is particularly important in view of the rapid depletion during the present century of our larger known de posits of high-grade ores, and the resulting danger of serious competition from foreign producers possessed of larger reserves of ores of higher grade, and who pay much lower wages. Improved technology in mining and milling is, therefore, essential to maintenance of the competitive position of our domestic producers.

Vir. SCRUGHAM. You have heard me read the duties of the Bureau of Mines, and the organic act creating the Bureau of Mines. Do not substantially three-fourths of the functions there mentioned come under the jurisdiction of the Mining Division?

Vir. JACKSON. I would not say so.
Mr. Serrgham. I will read them, specifically:

To conduct inquiries and scientific technologie investigations concerning mini. ing, and the preparation, treatment, and utilization of mineral substance was a view to improving health conditions, and increasing safety, efficiency, rconon. ? developn ent, and conserving resources through the prevention of waste in the mining, quarrying, metallurgical, and other mineral industries; to inquire 11 the economic conditions affecting these industries; to investigate explositts ar 1

peat-

Are all of those under the Mining Division?

Mr. Jackson. Only partially. As to the beneficiation of ores, that is principally under the Metallurgical Division.

Mr. SORU GIAM. How about explosires and peat, and their invenigation? Is that under the Mining Division?

Mr. JACKSOx. So, sir. There is an Explosives Division in the technologic branch.

Vir. SCRIGHAM. It goes on readin:):

ASSISTANCE RENDERED SMALL MINE OPERATORS BY MINING DIVISION

Wir. SCRUGHAM. Mr. Jackson, what does the Mining Division do to assist the great number of prospectors, particularly the small operators in mining?

Mr. JACKSON. For some years I have felt that we should stress assistance, technical assistance, to the small operators and prospectors who were obviously financially unable to employ competent technical help. The work that the Mining Division did and is still doing to some extent in the investigation of mining and milling practices at the larger mines forms the groundwork for assistance to the smaller operator.

Mr. SCRUGHAM. Will you give approximately how many men you have employed on such work?

Mr. Jackson. For small operators?

Mr. SCRUGHAM. I mean for work corresponding to the work done by the county agents under the Department of Agriculture.

Jr. Jackson. We have eight men, two of whom are devoting their time exclusively to district work, to assistance to the small operator, and the others give but part of their time.

The work that is designed to be particularly of assistance to the wall operator is of three different types. First we issue publications, prepared by the staff of the Mining Division, on subjects of special

alue to these small operators, such as Open Schedules for Gold and Silver Ores at Custom Smelters, Costs of Trucking and Packing Ore, Design of Small Wooden Headframes, Small-Scale Placer Mining Vethods, Sampling and Estimation of Ore Deposits, and Prospecting In Lode Gold and Locating Claims on the Public Domain.

Those are subjects suggested to us by the types of inquiries that we have been getting from the small operators, and we try to meet inquiries along particular lines by going into the field and making special studies to answer those inquiries.

Then, in the second place, we make studies of the different mining districts and issue publications describing the various mineral show

gs and existing development work thereon, and the methods of nining and milling employed, and giving freight, trucking and smelter harges on typical ores and concentrates from each district. These publications, giving authentic information, serve to bring the possi

ities of the districts to the attention of investors and may thus be benefit to small operators in need of financial help. Third, during visits to the various districts, engineers of the Bureau bo are experienced operators themselves and acquainted with the istest improvements in practices and methods, give, when so requested, technical advice to operators who obviously are financially "Enable to employ expert mining and ore-dressing technologists.

TALCE OF MINING DIVISION IN INVESTIGATING STRATEGIC WAR

MINERALS

Mr. SCRUGHAM. Could the Mining Division in any way contribute toward the national defense through an investigation of the strategic war-mineral situation as related to mining, and what would be the post, if that is not provided for in the Budget?

Mr. Jackson. Of course, the study of mineral deposits is the function of the l'nited States Geological Survey and we believe that the Survey is acquainted with most of the known possible sources of these minerals in the l'nited States.

Mr. SCRIGHAM. That is, the location of the mineral deposits and the character of those deposits?

Mr. Jackson. And something of their potentialities, in certain instances, are quite well known to the staff of the Geological Survey.

Now, the Mining Division might well study these deposits in considerably more detail, those that seem to justify further study, and make detailed plans for their development and extraction in readiness for a possible emergency. This should be supplemented by parallel investigations by the Metallurgical Division of methods of beneficia. tion of the ores and extraction of the metals. Thus, in the event of an emergency, complete plans for operation and schedules of equipment and personnel required would be immediately available.

Mr. SCRIGHAM. Is anything of that kind included in your budget for the coming year?

Mr. Jacksox. No, sir.
Mr. SCRIGHAM. None whatever?
Mr. Jacksox No, sir.

OBJECT OF EXPERIMENTAL TUNNEL

Mr. Scrrgham. Now, I think in item 12 of the justification you have an experimental tunnel, at a cost of $10,000. What is the purpose of this tunnel?

Mr. Jackson. In the first place -----
Mr. O'NEAL. It is an increase of $10,000.

Mr. Jackson. It is an increase of $10,000, last year there was $9,500 expended in preparation for this work.

Mr. O'NEAL. And that would mean that you would want $19,500 for the coming year? Mr. Jacksox. Yes, sir.

The object is to provide a field laboratory where research can be done on fundamental mining problems, where actual mining conditions can be duplicated, but interfering variables controlled, and which cannot be done in a small-scale laboratory nor in an operating mine.

Among the things that we desire to study are rock-drilling tests, tests of drill rods and detachable bits of different types and steel compositions, determination of best types of bits for different kinds of ground, pulling long rounds in small headings, and the like.

Another investigation urgently needed covers methods of preventing or controlling the production of dust in drilling, blasting, shovel. ing, chute drawing, and ore-cumping operations as a protection to the health of mine workers.

In that study we work in close cooperation with the Health and Safety Branch, which has already done considerable investigation along these lines, but in view of the present situation, wherein a number of our States have passed compensation law's, making silicoris a compensable disease, we must hnow more about this problem. If we are going to prevent the disease, we must prevent the dust. If we are going to prevent the dust, we must hnow what causes it, and how to eliminate it.
