SCIENTIST SEEKS MICE FOR STUDY OF MAN’S TREND • President Little, University of Michigan, Will Make * Long Trip. Bm United Press ANN ARBOR, Mich., May 6. Eager to prove to a skeptical science his theory that the tiny 'mousescourged through the ages—holds the predictive destiny of man, an unassuming young scientist will embark for Europe early in July in search of the rarest of rodents. The young scientist is Dr. Clarence Cook Little, president of the University of Michigan, whose expermits with mice in the field of genetics hajve attracted attention from the sritall circle of scientists who seek a solution to the great riddle of heredity. Dr. Little has promised nothing. He works alone with his experiments. # If hiq expectations are fulfilled, he told the United Press, he will be able to look 100 years into the future and reveal: The rate of growth of America’s population. ' *> _ The number of male and female children born to Ajnerican parents. The number of children born to each generation. The development of character in the United States. 100-Year Forecast If population has anything to do with war, the price of automobiles or the wages of labor, he believes be will be able to predict the condition of these present-day problems 100 years hence. In short, according to Df. Little, the despised mouse killed in a trap and thrown away as good riddance may prove a key to the secrets of Hie forces controlling the ebb and flow of population so that the nation will be able to bend its peoples under control. In a little laboratory at the University of Michigan here Dr. Little has been carrying on his experiments with mice for the past year. The laboratory presents a flourishing mouse farm. In eighteen months its population has grown from 400 to 10,000. Recently there have been so many mice produced that the feeding and housing problems have been acute. ‘'From experiments with the mice I have reached the conclusion that when widely distinct species are interbred the resulting generations of hybrids have a greater number of males than females,” Dr. Litttle told the United Press. “This phenomenon continues through successive generations of the species.” % • I.ike Human Race He then explained that it is an ascertained fact that the cross breeding of widely distinct races of humans shows that same majority of males in offsprings. "The conclusion to be drawn from these facts is irresistible,” he declared. “Whatever force it is that operates to produce more males from the interbreediyg of mice also works the same result in man.” It was this significant result that gave Dr. Little the broader idea he is ready to^rove. So far he has used only two species of mice In his experiments—tho com-

mon house mouse or mus musculus and the rare mouse or mus wagneri. The two are widely different. His purpose now is to find two other varieties, pure and uncrossed in their breed, that are distinct, yet not so widely different. These latter breeds, the object of Dr. Little's trip abroad, will be inter-bred and the offsprings closely observed. A comparison will be drawn between them and the hybrid offspring of the crossed house mouse and the Chinese mouse. Result Sought “The results will show whether the species from less widely dissimilar species exhibit the same tendencies toward male offsprings as I found in the case of offsprings from wWely different species,” Dr. Little said. The real test of the theory will come after the experiment with the foreign mice. Dr. Little proposes to apply the results to human society. “It has been shown that the laws of the life of mice also apply to human genetics,” he said. “During the past 175 years America has been populated, by widely dissimilar races of immigrant men and women, who have intermarried so as to produce several groups less widely dissimilar, but stiH distinct from one .another. “The big question to be answered is, what is going to happen when, during the next generations, these less widely dissimilar classes intermarry? “What works out with the mice can be expected to work out with the population of America.” In other words, the characteristics of sex, procreativeness and rate of future reproduction may be forecase in Dr. Little’s small laboratory here by the crossing of two species of mice. The second stage of the experiments will be attempted in Europe and the Faroe Islands Ibis summer. Desires Rare Specimen There the university president and scientist will seek the rare mouse known scientifically as the mus mu? ralis, which lives only upon the almost inaccessible Island of St. Kilda, near the Hebrides. With his three children, Edward, Louise and Robert, Dr. Little will sail for Scotland, where the national museum at Edinborough has promised its aid in securing the priceless j rodents. | After visiting Pldinborough he

The span is dedicated to the 100 years of peace between the United States and Canada and as a reminder that no fortifications exist on either side of the border from coast to coast.

plans to go by boat to the Danish Faroe Inlands, between Scotland and Iceland, he will seek another rkre species known as mus feroensis. These two sets of mice, according to Dr. Little, represent the required distinct, but not widely separated, species needed for the new experiments. The mice will be brought"-back to Ann Arbor and their interbreeding watched with minute care in the laboratory. “Success in these delicate experiments depends upon a number of factors, one of which is the health of the mise,” Dr. Little explained. “They must be jealously guarded." One set of the mice from St. Kilka perished before it could be gotten from that island to Scotland last year. The set was intended for Dr. Little’s laboratory. If the second stage of the experiments is successful, the hated vermin may prove itself to be a mirror in which science may see the reflection of national character fifty or a hundred years from now. $700,000 LOSS BY HAIL Icy Pellets Lie In Depth of Several Inches at Perry, Oltla. Bn United Press PERRY, Okla., May 6.—Another terrific hail storm has caused damage in Oklahoma. Chickens were killed by the dozens, wheat was driven to the ground and property damage amounting to thousands of dollars done by a storm near here. The storm lasted more than an hour and left hailstones lying to a depth of several inches after it had passed. Total damage today was estimated at $700,000.

cars and under heavy trucks, the government has tried out cement, brick, macadam, cobblestones and asphalt and is now miking a test of iron. Heavy iron plates as thick as those which protect the sides of battleships are now being laid and riveted to a concrete base. They are said to be as near wear proof as any material could be, but they have the disadvantage of growing uncomfortably hot under a bright sun. They are favored by the general slaft of the army, for as Gen. Gassouin points out, they would term a much needed reserve of iron in case a long war developed. Roads of secondary importance would be stripped of their iron and the concrete base would still serve as a roadway. Puzzles, of which the human race seems never to tire, were popular forms of amusement centuries before Christ. The oldest known puzzles date back to 1510 B. C.
