THE MICHIGAN DAILY Anti-Hitler Riots Greet Arrival Of German Visitor Policcien Battle Group Protesting Nazi 'Murder, And Terror' Reginie Chicago World's Fair Scheduled To Open Tomorrow I1 Scores Are Injure *1 Germaiin Representative To Exposition Quits Vessel Unnoticed NEW YORK, May 25.--IP")-Riot- ing broke out today at the North Germany Lloyd line pier in Brook- lyn in connection with the arrival in America of Hans Weidemann, rep- resentative of Adolf Hitler's German government at the forthcoming World's Fair in Chicago. A crowd of 1,000 men and women anti-Hitlerites, awaiting the arrival of the Nazi official, became enraged when it was learned that Wiede- mann and an aid accompanying him to the expositoin had been trans- ferred from the liner Columbus to a tug and taken to the battery in Man- hattan. Displaying bannersncondemning "the Nazi murder and terror re- gime," the crowds turned on the 50 uniformed police and 30 plain- clothes men, throwing bricks and bottles at them. Police engaged in hand-to-hand combat with the rioters and after a struggle arrested 13 men and women, the latter wearing red hats. The prisoners were locked up in a garage near the pier. Rioting broke out' afresh with the imprisonment of the 13. With police standing guard in front of the garage door, the crowd again charged them. Reserves were called out and in a. short time additional police forces arrived on foot, on horseback and in automobiles. Order was restored only after police drew their guns and levelled them at the crowd. During the melee more than a score were injured, including four policemen, one of whom received a fractured right arm. Physics Teachers To Ihear Goudsmit, Cork Professors S. A. Goudsmit and J.M. Cork, both of the physics department, will speak before the regular spring meeting of the College Physics Teachers of Michigan at 10 a. m. tomorrow in Ypsilanti. "Experi- ments on Nuclear Structure" is the title of the talk to be given by Pro- fessor Cork. Professor Goudsmit will address the meeting on the "Theory of Nuclear Structure." After the morning meeting in Charles Mc- Kenny Hall, a luncheon and sevcral excursions will be held. .' ,, -Associated Press Photo With all its major projects complete, "A Cenitury of Progress" exposition on Chicago's lakefront is a scene of last-minute preparations for the official opening May 27.

Five Cars In Indianapolis Race Designd By Graduate Students Five of the qualifying cars which will race at Indianapolis Memorial day have bodies designed by two University graduate students, C. L. Johnson and E. D. Palmer. All of the cars are semi-stock Studebakers and all qualified for the race at speeds ranging between 110 and 116 miles an hour. They. were driven by Cliff Bergere, Tony Gulotta, Luther John- son, Zeke Meyers, and L. L. Corrum. Since the first of the year John- son and Palmer have been conduct- ing tests in the wind tunnel of the East Engineering Building to deter- mine the most efficient body design for a car racing at Indianapolis. They encountered many practical difficulties in designing bodies for these cars because they must travel 500 miles at over 100 miles an hour on a bumpy two- and a half mile brick track that is slick with oil and shared by 41 other cars. Because an average race car travel- ling at 100 miles an hour uses about 85 per cent of its power to push air out of the way, the bodies were de- signed to approach a perfect stream- lined form, Palmer said. However, this is prevented by such practical considerations as tire changing,' which makes it impossible to cut down air resistance around the wheels. Tires can be changed in 17 seconds and mechanics resent "fair- ing"/ or any other construction that adds to this time. Another obstacle to streamlining is a ruling compelling the mechanic riding with the driver to look out behind whenever the cars rounding a turn and to signal to the driver whether the way is clear. This neces- sitates an-open space behind the me- chanic's head that sets up eddies and produces a drag on the car. The effects of cross winds, which often upset cars and cause crashes because of swerving and skidding, have been taken into account in the design of the bodies, Johnson stated. Because of varying wind conditions around the track, interfering air cur- rents make steering a complex prob- lem; but it is simplified by the appli- cation of certain body contours and features of design. Streamlining not only adds to speed by reducing the air resistance but it increases gas mileage and therefore a snaller gas tank may be; used with a saving in weight and a-gain in speed. All of the five cars are between 85 and 90 per cent stock and are con- siderably heavier than the special- ized racing jobs that they are com- peting against. In spite of their ad- ditional weight, which is an advant- age in enabling them to endure the terrific pounding, the fastest of the five was only three miles an hour be- hind the best qualifying time yet turned in. WORLEY, TAPPING RETURN Prof. John S. Worley of the trans- portation engineering department and T. Hawley Tapping, general sec- retary of the Alumni Association, are back at their desks today after hav- ing returned from Kalamazoo, where they addressed the University of Michigan Club of Kalamazoo. Detroit Trade Shows Large Gain In April Federal Reserve Bank Announces City's Sales Increase 50 Per Cent CHICAGO, May 25.-(/P')- The Chicago Federal Reserve bank in its monthly report of department store trade today said that Detroit stores, with a gain of 50 per cent in April1 sales over March, led cities of the seventh Federal"Reserve district. The report was especially favor- able, showing an average gain of 23 per cent in the month's sales against a 10-year average of only 8% per cent. Sales were only 15 per cent less than in the same month last year, representing the smallest decline in the year ago comparisons since July, 1931. Whereas Detroit enjoyed the larg- est gain it also suffered the greatest loss from April, 1932, the figure be- ing 24 per cent. In" sales of furniture and house furnishings the April total was 26 per cent greater than March in the district and comfortably over the five-year average gain of 21 per cent. Sales for the first four months of the current year as compared to the same period in 1932 were repoi;, ed lower by the following percent- ages in wholesale lines: Groceries, 16 per cent; shoes, 19 per cent; drugs, 25 per cent; drygoods and electrical supplies, 28 per cent, and hardware, 29 per cent. Auto Ban Will Be Less Rigid This Summer Modiiication Of Regents Ruling Is Announced By Assistant To Dean The Regent's regulation prohibit- ing students from using motor ve- hicles will be modified for the sum- mer session as usual, according to Walter B. Rea, assistant to the dean of students. Besides the usual permits granted for family, commuting, and business purposes, Mr. Rea said, during the summer session permits are granted for a limited recreational use of auto- mobiles. This permit enables students to carry student passengers, he said. Mixed company in an automobile after 9 p. m. will be considered a violation of the regulation, Mr; Rea stated, although women ands men may both ride in cars before that hour. In past years it has been cus- tomary to consider the grades of the applicants for driving licenses, Mr Rea said, and it has not been de- cided what policy will be followed this year on that matter. Those who have been engaged in professional work and are returning to the summer session are not re- quired to observe the automobile re- striction. Mr. Rea warned students to ob- serve the relaxation of the restric- tion as it was published in the Daily Official Bulletin, pointing out that the time when a student is permitted to drive is not determined by the time he finishes his last examination, but by the relaxation which applies to his class in his school or college. Gasses From Burning Clothes Cause Deaths NEW YORK, May 25,-(/P)-Dead- ly gases from burning clothing were disclosed today as probably the real cause of a large percentage of the 10,000 deaths which occur every year through fire in the United States. A report of the American Chemi- cal society found that burning of woolen materials gives off such dangerous gases as carbon monoxide, carbon dioxide, hydrogen salfide, hy-1 drocynaic acid, and ammonia. SCIENCE AIDS DEMOCRACY At last science has come to the aid of campus democracy. An electric voting machine guaranteed to be acid proof was displayed at the electrical engineering show at the University of Minnesota last week. It was stated that they would be used in future elections on the campus. -Associa -ed Press Photo Guy C.
