10 Woman Scientists Who % Carry on Research IRork For Uncle Sam " ■> ~. t .Government Group Includes Highest Ranking Geologists in the United States—Two Paleontographic Illustrators, a Couple of Medical Bacteriologists and an Expert in Marine Invertebrates. . . BY JAMES NEVIN MILLER. rHEY stand squarely on their own feet, asking nothing at all from a man’s world of science except that their work be judged on its merits alone. Such are the women scientists at ■*' lached to Uncle Sam’s great research labora tories In Washington. All told, the genuine “topnotchers” among them total only a trifle more than a baker’s dozen. Yet all show the true qualities of leadership; they possess that which is referred to as “womanliness,” while many receive prominent mention in the annual American Men of Science, a tiny volume issued annually, containing a who’s who of those who have accomplished important scientific work in the United States. Included in this group are three geologists, two paleontographic illustrators, two medical bacteriologists, an expert on marine inverte brates, one assistant curator, an explorer, a beverage chemist, a “nematodist,” a “cytologist" and a “mycologist.” Probably the most readable “human-interest” story that might be told about any of these dis tinguished scientists is the one about three women connected with the United States Geo logical Survey—Dr. Florence Bascom, Dr. A. F. ' Jonas and Dr. Julia A. Gardner. Certainly this little group comprises the highest-ranking women geologists in the United States. Indeed, most geologists who now are prominent in commercial pursuits have spent an apprenticeship with the Geological Survey, which is admittedly the best training school for the Nation's leading experts on rock formations.

Whereupon a position was offered her, subject to the customary Civil Service regulations. Miss Bascom accepted, much to the regret of the faculty and students of Bryn Mawr. It is a coincidence that two of Miss Bascom’s most proficient students, Miss A. F. Jonas and Miss Julia A. Gardner, who were graduated a few years later, also found excellent posts with the survey. Tod?y Miss Bascom is regarded with a great Seal of affection and respect as the dean of the Nation’s women geologists. She and her two former students have published a number of authoritative scientific works on America's geological formations. Moreover, feme years ago to Miss Bascom came the honor THE SUNDAY STAR, WASHINGTON, D. C, MARCH 22, 1991. IcpiP I p. i' 1 .- & &■'.>■ jsgyj Miss Mary King Sumner at work in the laboratory of the Geological Survey. of being the first woman to belong to the dis tinguished Geological Society of America. Working hand in hand with both men and women geologists are two well known “paleonto graphic illustrators” at the Geological Survey, Miss Frances Wieser and Miss Mary King Sumner. In their chosen field these two experts rate with the foremost in the land. An im portant phase of their work consists in making drawings of fossil rock formations, dating back perhaps millions of years, and retouching photos of other specimens. A powerful microscope is usually necessary in this connection, for often times the specimens used to make such pictorial material are smaller even than the finest pin point. The dents, cracks and crevices which such drawings and pictures delineate are 6t vast im portance to State and national geologists, for they are the direction signs which indicate - where new supplies of oil, coal and valuable rock may be found, and at approximately what distances below the earth’s surface the deposits are located. If the rock specimens are tiny they are mounted on special glass slides and studied carefully under a binocular microscope which magnifies as much as 200 times. This has a • special micrometer which helps measure the magnified specimen so as to make the drawing in the desired scale. By a curious blow-pipe arrangement speci mens are sprayed with chemical solutions which whiten their surfaces so that even the most delicate lines and marks may be closely ob served. This solution also destroys any discol orations that might obscure the all-important lines, indentations and bumps. After classifi cation of fossils in this manner it is possible to establish the geologic age of every rock for mation and from this knowledge it is only one more step to a direct correlation of oil or coal producing strata. TWO bacteriologists who have made notable discoveries to aid the Government’s relent less warfare against mysterious diseases are Miss Alice Evans and Miss Sara E. Branham, both with the hygienic laboratories of the United States Public Health Service. Truly, Miss Evans is a living martyr to medical science, for again and again she has risked her life in connection with the important research work. Already she has had "Malta” or “undu lant" fever, caused usually by drinking the in- „ fee ted milk of goats or cows. The strange ailment has been a puzzle to the medical fraternity, both as to cause and possible cure. So far no cure has been found, but science now knows that a thorough pas teurization of milk will serve as a preventive. Miss Evans’ contribution to the world’s knowl edge of this mysterious disease has been of great value. As far back as 1918 she made the discovery that there is a very close relation between the organism which carries “undulant” fever to humans qnd that which causes conta gious diseases in hogs and cattle. It was found that the two organisms are indistinguishable by ordinary laboratory methods, although a slight difference can be detected by the use of a cer tain complicated and tedious test. The dis covery by Miss Evans was confirmed later by qualified investigators in the United States, Austria, Italy, The Netherlands, Egypt, Japan pjfl | "Mllß •' " ' • Bhffr, \m 1 **^ jiori '*‘^ n . .>>*,^iß ifiii y4gnes Chase, Uncle Sam’s chief woman explorer.

Her research work requires much more than • smattering of many tongues. She has eon* ' quered scientific French, in which new tongue* . twisting words are being coined virtually all the time. The only woman in the entire Smithsonian Institution who rates the important title of - curator is Miss Doris Cochran of the division of reptiles and amphibians. Every year she catalogues between 2,000 and 3,000 speci mens of creatures that rate scientifically as “cold-blooded vertebrates, with the exception of fishes, none of which achieve the steady high temperatures characteristic of mammals.” This is the second largest collection of the kind in the entire world, the largest being in the British Museum. Included are turtles, .„ crocodiles, alligators, snakes, frogs and sala manders. Ncne of these specimens is alive. But they do have in their scales, color, sise and proportions certain almost mathematically pre cise characteristics that fit into a definite formula for differentiation of species. DIOHT here is where Miss Cochran’s sci entific poet is so important. She has to classify every one of the specimens submitted to her, and this is an extremely difficult, slow and painstaking job. For not only does she have to put every type of modern reptile into Its proper scientific cubbyhole, but she like wise must piece together, correct and alter. Continued on Thirteenth Page
