It was but a few short years before plans for this southern station began to take concrete form. In June, 1908, Mr. Lamont author- ized Professor Hussey to proceed to- ward the construction of a telescope of 24 inches aperture for the study of' the double stars of the southern por- tion of the sky. He made an initial contribution of 1,000 dollars. During April, 1909, Professor Hus- sey studied the 26-inch refractor at the Naval Observatory, in order to se- cure data for the designs of the Ann Arbor telescope. Plans and drawings for the new telescope mounting were begun in 1910. A contract for a 24-inch lens was placed with Alvin Clark and Sons in 1911. A pair of discs for a 24-inch lens were ordered from a French and -? a German company in 1913, but these were never delivered. It is said that during the World War, the govern- ment of both countries seized the discs and cut them up to be used for PROF. WILLIAM J. HUSSEY field glasses for their armies. In 1915, Lundin, who had been rect the Lamont Expedition, and Dr. selected to perform the exacting op- Rossiter was ordered to continue the tical work on the lens, had died. undertaking that Professor Hussey During the years immediately follow- had so -hopefully planned.

At 20 m.p.h. the best he is able to do on a dry pavement is to halt his car after going a distance of :7 feet from the time he had his first yarning to stop. This is merely one of a set of in- teresting facts uncovered by Frank 0. Olmstead, assistant research en- gineer of the Michigan State High- way Department in a survey conduct- ed by the department in the interest of public safety. The survey, which includes results from the reaction tests given at the Engineering Open House last spring also showed that after four years experience the individual ceases to improve as a driver and that the drivers between the ages of 17 and 31 are the most alert. The results of the survey, which have not been officially published as yet, are of particular interest at this time because of the fact that the machine to test the driver's reaction to a stop light is at the Union where it will remain for the remainder of the week. The importance of split-second driving reactions is readily seen when one realzies that at 40 m.p.h. an au- tomobile travels at the rate of 57 feet per second. Mr. Olmstead found that the faster drivers have more acci- dents but since they drive more miles than the slower-moving motorist the chances of accident are equal to all motorists. Mr. Olmstead drew the conclusion from his survey that the best means of influencing drivers to drive safely is an educational program pointing out to them the need for alertness at all times. Poets Best At 25, Psychologist Finds An Ohio University psychologist has reported, after research, that writers reach their peak in literary production at forty-one, chemists are best between thirty and thirty-five, inventors at thirty-five, and astron- omers between forty and forty-five. According to Dr. Harvey C. Leh- man, poets produced their best work between twenty-five and twenty-eight and short-story writers before thirty- five. Doctor Lehman asked English pro- fessors of various universities and colleges to select what they regard- ed as the 2,000 best works in litera- ture. Taking their selections, he drew a graph showing the average number of miscellaneous publications per chronological age level per living writer. The graph showed writers' productivity ascending more rapidly before forty-one than descending af- ter. There was, however, a sharp descent after forty-four, Doctor Leh- man said.

Leaders Consider Role Of Vandenberg Half Of June Convention Delegates Are Chosen; Steiwer Also Backed WASHINGTON, April 25. - OP) - The names of Senators Vandenberg of Michigan and Steiwer of Oregon assumed increased importance in Re- publican councils this week as the personnel for the June convention became almost half complete. If a deadlock threatens between the now leading possibilities for the presidential nomination, friends of the two legislators would be in a more starategic position to advocate them at Cleveland. No suen aeadlock has been predict- ed. But observations heard at the capitol following endorsement of Van- denberg by the Michigan Republican been named convention keynoter, in- dicated party leaders had not dis- missed the possibility. A way to har- mony is the principal goal of some. Action today in Colorado brought the delegates so far named to 477 of the 1,001 total. Of these an un- usually high percentage are nomi- nally uninstructed, 376 in all. Claims by some followers of Gov- ernor Landon of Kansas, Col. Frank Knox of Illinois and Senator Borah of Idaho overlap to an extent that suggests the full story must await the actual balloting. WThether any of these three are found within striking distance of a nominating majority, or 501, at the outset may determine the course of advocates of Vandenberg, Steiwer, Senator Dickinson of Iowa or others at present talked of as "dark horses." Borah said he would decide whether to go to Cleveland as a delegate, which would be necessary for service on the committee, by the time the Idaho delegation is picked May 9. 4 Arbor. mont-Hussey Observatory was In the late summer and autumn of licly opened and dedicated. 1925 the Lamont Telescope was fully ceremonies were held under the assembled by Mr. Colliau for final of the Lamont telescope and testing and adjustment on the than 50 of the prominent towni grounds of the University's Detroit of Bloemfontein, were present.

By HOWARD W. BLAKESLEE (Associated Press Science Editor) ! BOSTON, April 26. - ()P) - A little of the heat which destroys burned papers resurrects them photograph- ically, makes black pages seemingly white, and print and writing distinct, in a new development of -infra-red photography here. The heat photography recreates the original page of any paper not crumbled to dust. The technique was worked out by Gustavus J. Es- selin, chemical consultant. Pages so coal black that neither eye nor microscope distinguishes traces of their original printing or, writing come out white to gray in the infra-red photographs. The words written on them retain their original blackness, form and clarity. Heat 'Rumples' Paper The pages might appear all white except for the fact that heat always rumples them. The white color is re- stored only at the level of perfect focus of the camera. Areas slightly out of focus appear gray or dirty. The infra-red, or heat rays, photo- graph what is left of the original structure of the paper and the print in the ash remaining after the fire destruction.

Liberty i i This new use of invisible light dif- fers from the work done with ultra- violet, which brings out things often invisible to the eye, like erased writ- ing and chemical spots. The ultra- violet rays cause the invisible sub- stances to fluoresce, that is, to give off light of their own. The Infra-red rays produce no secondary glow, but take the place of visible light in restoring to sight >omething gone beyond the reach of visible reflection. Together the two processes promise to narrow still further the crook's chances of com- pletely destroying evidence. In fires valuable papers, enclosed in filming cases where they do not blaze, are often destroyed by heat that blackens them completely with- out crumbling. Such papers turn white again on the.infra-red plates. The burned inks still appear black because they absorb infra-red to blackness the same as they absorb light.
