By the Associated Press. | CAMBRIDGE. Mass., July 6.—Inven- | tion of a mechanical brain whose gray | matter is mostly light was announced today by the Massachusetts Institute of ‘Technology. | The brain is a calculating machine, which makes use of light by a trick almost as simple as the cutting out of paper dolls. It performs in & few min- utes mathematical problems which by | human brains and hands require any- | thing from hours to days. Citizens Will Spy On Rum Violators In Atlanta Drive By the Associated Press. ATLANTA, July 6—A com- mittee of citizens to report law violations, particularly prohibition offenses, that come to their at- tention is being formed here as a result of the dry agitation against Mayor James L. Key for char- acterizing the eighteenth amend- ment as “a failure.” Leaders of the new organiza- tion, which s known as “The Greater Atlanta Prohibition and Law Enforcement Club,” include John A. Manget, a prominent capitalist and veteran reformer, and C. A. Norton. Manget pre- sided at the recent rally of prohibitionists, who ~demanded the resignation of all office- holders who are critical of the dry laws. Stage Star's Father Dies.

NEW YORK, July 6—Activity in large building enterprises, although not matching that of boom years, is con- tinuing on & substantial scale, Truman S. Morgan, president of F. W. Dodge Corporation, told the Assoclated Press today in announcing million-dollar contracts awarded from May 15 to June 30. The total value of 26 of these laige { Important | work on the projects is now starting or will begin very shortly.

Mr. Morgan pointed out that these under- takings were well distributed as to. lo- ation and included a theater in New York City to cost $1,000,000, a post of- fice in Boston listed at $4,648.000, a hydroelectric dam in Arkansas to cost £13,000,000 and a city hall in St. Paul vhich will cost $3.000,000. All of these huge expenditures are | being made on structures which ex- hibit the characteristics of permanence and fire safety,” Mr. Morgan said. Other buildings and public works in- cluded in the 26 projects are offices and stores to cost $5,000,000 in New York City, a New York City apartment to| cost $1,200,000, a chapel in Cambridge, Mass,, to cost $1,000,000.

MINERAL PRODUCTION IN ALASKA FALLS OFF Gold and Coal Mining Show Gains Despite Decrease in Total Laid to Low Prices. The United States Geological Survey announced that Alaska's mineral pro- duction showed a shrinkage from $18,- 066.000 in 1929 to 313‘315.000 n :930. Gold production, however,; increased from $7,750,000 to $8.476,000 and coal mining showed a gain of more than $100,000 to $631,000. The largest loss was in_ copper production, which fell from $7,130,000 to $4,244,600. The decrease, said the survey, “is in- terpreted as being due not only to the very low prices that prevalled, but also to the deterrent effect of these new prices on new enterprises and in dis- suading operators from making even as DRUM TO PRESENT C.

Part of Graphs Transparent. The paper on which these graphs are traced is treated so that the portion below the graph is transparent. The effect is like cutting out paper dolls, leaving the figures of the dolls outlined as openings in the original card. The treated graphs. when a light is placed behind trem. quaintly resemble a lumi- nous row of mountains or the skyline of a city at sunset The amount of light coming through the treated graphs depends upon the shape. size and angles of the peaks and valleys which contain the secret of the mathematical p oblem. Measuring the volume of this light gives the essential diffcrence between any two graphs, or &ny scts of graphs. Second Light Measures First. The brain epalyzes this light—does it n two cr three minutes, with the aid of two photo c cells, The light from the graph falls upon one of these cells. Upon the other is directed a light <beam of known intensity. A crank is turned to change the inten- sity of the kn'wn beam until the photoelectric “eyes” show that its vol- the same as that from the thereby revealing how much comes through the graph. With this measurement _established, the orain completes its problem by the mathematical method known as inte- gration.
