The Diamond mechanical soot blower system, manufactured by the Power Specialty Co., Detroit, Mich., consists of a permanent installation of units arranged in groups to fit the design of the various boilers to which they are attached. The units are so arranged as to effect the cleaning of the fire surfaces of the boiler, particularly the tubes, by means of steam jets. When this steam is released among the tubes at a velocity of approximately 2700 ft. per sec. (assuming a pressure of 150 lb.), a perfect whirlwind of currents is created, reaching all the nooks and crannies of the boiler, and thoroughly removing the particles of soot and fine-ash accumulation. This operation requires but a moment's time-from 20 to 50 sec. per unit¬and is performed from two to four times a day, while the boiler is under full load, using a greatly decreased amount of steam and labor as compared with the hand hose or any other system of blowing. Moreover, this cleaning is effected without admitting air, with its cooling effects, to the boiler setting. The Diamond model "G" blower consists of five principal elements as follows: 1. A head through which the steam passes from the main supply line when the valve is opened. The head is the foundation element to which the other elements are attached. 2. A wall box which is bricked into the setting. The box supports the unit, and is so constructed that the blower can be turned freely without admitting air to the inside of the setting. 3. A blower element running cross-wise of the bank of tubes, and consisting of a small header with nozzles so placed as to discharge steam between the boiler tubes. 4. A sheave or hand wheel by means of which the blower element is rotated. 5. Bearings attached to the boiler tubes which support the blower element and permit it to revolve freely. The nozzles from which the steam issues are designed on the principle of the Venturi tube, and vary in design for different pressures. The expanding walls of the Venturi nozzle increase the velocity of the steam over 200 per cent., as compared with a nozzle having a straight orifice. Thus, the velocity of the steam issuing from a straight nozzle at 150 lb. pressure is 912 ft. per sec., whereas, at this pressure the velocity of the steam issuing from a Diamond Venturi nozzle is 2795 ft. per second.

My predecessor in the office of President of the Institute started a custom of visiting the various local sections, thus obtaining their points . of view and their ideas as to how the Institute can best serve the interests of its members. Exceedingly valuable- exchange of ideas was thus brought about. I am following this custom as far as the limited amount of free time at my disposal will allow me, and I trust that my successor in office will appreciate the benefit to be derived from following the custom thus initiated and will continue the swing around the circle of the local sections. The activities of the Institute are increased by the prestige gained from large numbers and I trust that every member of this local section will consider himself a member of the committee on increase of membership and will see if he is not able during the coming year to gain at least one new member for the Institute. This is a perfectly possible proposition for, although the membership of the Institute is at present approximately seven thousand, I feel sure there are at least seven thousand more men in the United States who are interested in mining, metallurgy or geology from the metal-mining point of view who would make admirable members or associate members of the Institute. The first consideration of the Institute as a body, and of each member as an individual, is to win the war and defeat the Huns. In order to accomplish this, the Institute, as a body, has cooperated with the other national engineering societies and the great bureaus of the Department of the Interior, the United States Geological Survey and the Bureau of Mines in forming committees to study and advise the Government on pressing problems of vital importance.

Feeders and Grizzlies are links of the utmost importance in the chain of milling operations, but, hitherto, the close analysis granted to other equipment has been withheld from these machines. The development of. the self-clearing drop-bar feature, the result of many years' practical study of the problem, has made possible a machine which will

SHELBY M. HARRISON,* New York, N. Y. (written discussion ?).¬Your secretary requested a brief description of the Russell Sage Foundation, in order that members of the Institute, if they should desire to avail themselves of it, would know what type of service is offered to them through our institution. The foundation was established in 1907 by the gift of Mrs. Russell Sage of $10,000,000 as a capital fund, the income of which is to be spent for the improvement of social and living conditions in the United States. One of the lines of activity which the foundation has felt would lead toward this end is the development and promotion of community surveys; and because the scope and methods followed in these surveys are very similar to the scope and method of much of the institution's work in general, an idea of its main activities can perhaps be given best by describing one of our surveys. Incidentally, it may be pointed out that antecedent to the survey stand at least two important facts: first, the recognition. that communities are active, not static forces, that they develop, that changes in. material and human relationships occur continuously, and that with them come new social and civic problems which must, in many cases, be diagnosed and prescribed for anew; and second, the reality of scientific advances along lines which make possible at least some measure of solution of the problems. Evidences of these changes are abundant; many of them are found in the rapid growth of cities in the last few decades. Villages in agricultural districts, places where everybody knew everybody else, where the pulpit had been long the chief or only influence molding public opinion, where the air was unclouded by the smoke from factory stacks, where the water supply was not affected by pollution, where sunlight and building

EUGENE WESLEY SHAW,* Washington, D. C. (written discussion ?).-Studies of the probable future production of oil wells and fields-particularly those in the nature of the recent work by Lewis and Beal, having the object of increasing the percentage of recovery-rank, in both practical and theoretic value, very high, if indeed they do not outrank all other petroleum investigations except structural surveys. Even such surveys, although saving untold millions that might have been spent in prospecting unpromising territory, may have less ultimate value than generally supposed, for it may perhaps be argued that much if not most of the condemned territory will sooner or later be tested-some is already productive-and the most that can be rightly claimed is the recovery of cream first; also that the consumption of the richest portions first cannot be extenuated, as it might with some resources, on the ground that if the best is not taken now it will deteriorate.

The Institute maintains for the use of members (and especially for the use of out-of-town members) a reading and writing room, where all usual office facilities are available, including telephone, telegraph, receipt, forwarding and care of mail and express packages, etc. A file of current magazines is also maintained in this room, and the Institute's staff will lend its best efforts to serving the members in connection therewith. The Institute also maintains for the use of its members free dressing rooms, library research department, etc. Attention is called to these facilities at the present time in the belief. that they may be especially useful to out-of-town members in connection with the Meeting.

THE following example of the practical application of engineering geology is of interest in that it demonstrates the advantage of keeping accurate records of all wells, whether drilled by one's self or by others, together with the advantage gained by gathering such data during the process of development. The fault described was found in the autumn of 1915, during the hurried development caused by the discovery of the famous Gusher Bend pool in Red River Parish, Louisiana. The writer was at the time employed by one of the operating companies as geologist, and the example is a portion of the routine work. LOCATION The oil fields of northern Louisiana and east Texas are located in Caddo, Bossier, De Soto and Red River Parishes, Louisiana, and Marion County, Texas. A very narrow strip of the eastern portion of the latter is productive. The producing oil pools are known as the Caddo Field, in the northern part, and the De Soto-Red River Field, in the southern. The two fields are 60 miles apart. There are several gas fields between then, but no important supply of oil has been found, though there are several producing wells in the Anona chalk, locally called the chalk rock, in the Elm Grove gas field in Township 16 North, Range 11 West (see Plate 1).

AN elaborate series of experiments has been conducted during the past three years at Irvington, N. J., which has resulted in the perfection of a process for the manufacture of smokeless fuel from high-volatile coals, and for the recovery and refinement of the coal-tar products derived therefrom. These experiments have been financed by Messrs. Blair Co., of New York, and were conducted under the direction of Charles H. Smith, a member of this Institute, and the inventor of the process. The low-temperature distillation of coal has interested investigators for many years. Sporadic attempts have been made to solve the mechanical problems, but until the Smith process. was developed, they were not carried to conclusions of economic value. The present coal shortage and the increasing demand for smokeless fuels make this subject one of timely interest.

Officers of the Institute have been entertained by, members at nine meetings in different parts of the country during the months of March and April. Institute policies have been discussed by the officers and by members present at the different meetings, with the result of bringing about a better understanding of Institute policy among the members; it has also been made clear how various suggestions are viewed by members who are not all in close touch with Institute activities and with the policy of the Board of Directors. President Jennings devoted his remarks chiefly to an account of Institute activities in connection with Government service for the war, and presented an able address on the relations of labor and capital; with special relation to possible changes that may be necessary during the reconstruction period following the war. This carries forward the suggestion made by him in taking up the reins of government at the Annual Dinner on February 20, 1918, and makes available a paper which has aroused great interest at the different meetings; this address will be found on a following page. In referring to Institute activities in connection with the war, the President mentioned especially the Naval Consulting Board, the War Committee of Technical Societies, the War Minerals Committee, and the census of engineers prepared not only by the Institute in connection with the Bureau of Mines, but also by the American Society of Civil Engineers, the American Society of Mechanical Engineers and the American Institute of Electrical Engineers. He announced also the appointment of two committees, one on ferrous and one on non-ferrous metals, advisory to the Tariff Commission, and the appointment of a member of the Committee on the Excess Profit Tax, having especially to do with the question of excess profit taxes on gold mines. He also announced the appointment of a new committee known as the Committee on Industrial Organization, which will devote its energies largely to the question of relations of capital and labor and of "human engineering."

FRED TURRELL GREENE Fred Turrell Greene was born in Brooklyn, N. Y., Nov. 22, 1872. His father, William A. Greene, was born in Providence, R. I., and his mother, Angenora Semlear, was born in Brooklyn, N. Y. Fred's early school clays were spent in Boston, whence his father moved to Canada in 1882. Attending first the Collegiate Institute in Toronto, .then the High School at Berlin (now Kitchener), Ontario, where he graduated, Fred progressed to the Toronto University and the Michigan College of Mines, at Houghton, where lie graduated in 1897. He secured employment almost immediately at Butte with the engineering force of the Boston & Montana Consolidated Silver Mining Co., under Chas. S. Batterman. In 1899 he went to Rossland, B. C., where he spent more than a year as mining engineer and assistant superintendent of the War Eagle Consolidated Mining and Development Co. and the Center Star Mining Company Ltd. Returning to Butte in 1900, he acted as assistant geologist for the Anaconda Copper Mining Co. until 1906, when he filled a similar position in St. Paul with the Great Northern Railway for about two years. From 1908 until his tragic death on Christmas day, 1917, his headquarters were in Butte, where he enjoyed an excellent reputation -as consulting mining engineer, with a rapidly widening circle of clients. During the past four years he had been consulting engineer for the Elm Orlu and other mines controlled by Hon. W. A. Clark, and was in charge of underground developments and law-suit preparations for the celebrated apex case between the Elm Orlu and the Butte & Superior companies. At the time of his death he was in charge of similar work for the Utah Metals Co., in connection with their mines at Bingham, Utah. He was also for some years active in the Coeur d'Alenes, as consulting geologist for the Federal and other companies there, and was considered an authority on this as well as the Butte district. Mr. Greene was unmarried, and is survived by his parents, a younger brother, who is in the army, and one sister, Mrs. James A. Hatch, of New York. Some of the most important and valuable ideas regarding the nature and origin of copper ores have originated in Butte, since that district is not only one of the greatest examples of mineralization known in any land, but has gone through a long course of mining litigation, and was, one of the first to be studied intensively by geologists. In connection with the early investigations, as well as with the most recent in that camp, Mr. Greene played an important part. His conscientious devotion to his duties and his intelligent handling of the problems presented for solution sufficiently explain the esteem in which he was held by his employers and his professional associates.

GEORGE F. COMSTOCK,* Niagara Falls, N. Y. (written discussion?).¬I have recently had the pleasure of reading Mr. Miller's interesting paper, and would like to call attention to a reference to this subject which apparently has escaped his notice. It is an abstract of a German research on the subject of nitrogen in steel, and appeared in the Iron Age of Feb. 17, 1916, page 432. Photomicrographs of needles such as Mr. Miller found in his welds are given, and their identity is discussed. The conclusion reached is that the needles are slip lines due to the brittleness of the ferrite crystals caused by their absorption of nitrogen. The deformation necessary to develop the slips is supposed to be accomplished either in cutting or polishing the microsections or by cooling strains after welding. It seems very reasonable to expect that nitrogen would he absorbed by steel in either electric or oxy-acetylene welding, and the reference I have mentioned gives instances of many unusual structures resulting from the presence of considerable nitrogen with carbon in steel. But the nitrogen is .rapidly given off from steel by ordinary annealing in air, hydrogen or vacuum, and this would explain the disappearance of Mr. Miller's needles after annealing. I think the conclusion that the needles are cementite might well be revised in view of this German work on nitrogen.
