Of course, the preserving of the health and vigor of the nation’s Chief Execuive far transcends in importance the experiment in the Philadelphia Zoo. Nevertheless, it is upon the weekly bulletins which record the progress of the two baby primates that the ey of science are focussed. The weather which will be manu- factured for President Hoover will differ greatly from that to be supplied to the lower anthropoids. Man works best in a temperature ranging be- "1} of dust and dirt which are suspended in it. Then there are cold pipes, con- trolled by the thermostats, over which the air passes in the cooling process. The task of conditioning air for humans is comparatively simple, since we are familiar with our own requirements. When scientists try to reproduce ideal jungle conditions, however, the task is more difficult. It was about two months ago that “Maggie,” the orang-utan, gave birth to her second offspring. Just about the same time “Marianne,” the chim- panzee, gave birth to her second, too. The baby of ‘“Maggie” was only the second orang ever born in captivity in the United States, and only the third in the world, And births of chimpanzees in cap- tivity have been rare events. The first-born of both Maggie and Marianne — born about two years ago —lived only a IF “WISTFUL EYES” LIVES, HE'LL BE UNIQUE One of the Most Unusual Photographs Ever Made of a Baby Orang-utan.

All of them seemed to grow happier immediately, and since they were transferred none of them has contracted any ailments. “Bamboo,” a gorilla, which was born three years ago, and given a little chimpanzee for a playmate, seems particularly well pleased with the new arrangement. Most important of all, however, is the fact that at the time of this writing the two little babies have shown noth- ing but vigor and playfulne; Specially adapted machinery draws in the air, which is either warmed or cooled, as desired, by passing it over a system of pipes, controlled by ther- “Maggie's’ ' Two- Philadelphia Society Matron, Shown Holding Julius, Little Chimpanzee Which Lived Only Six Months in Spite of the Greatest Care.

This dry condition often pre- vails in a heated house in the Winter- time, and exists to a lesser degree on the Sahara Desert. Experts know now how much hu- midity the human body needs in order to maintain the maximum condition of health. Because of this knowledge the weather conditioning apparatus in the White House executive offices was installed with a certainty that the working conditions of President Hoover could be improved.

In the President’s office these con- ditions will be supplied. In the monkey house, however, a much higher temperature, with 50 per cent humidity, has to be maintained.

But science is determined to save the lives of these two new baby anthropoids. Zoologists call them “the most valuable babies in -America.” Curator C. Emerson Brown is con- fident of success. The last baby orang-utan died just after his first birthday from a complica- tion of ases. Marianne’s little chimpanzee caught cold, contracted spinal meningitis and died when he was only six months old. ““They were exposed to air to which they were not accustomed,” said emi- nent zoologists, ‘“and to bronchit; laryngitis a n d pneumonia breathed into the air by spectato: So Curator Brown and his assistant, Jimmy McCrosson, built glass cages in the monkey house.

Then an electric fan expels the conditioned air into the room or cage. The aim of air-con- ditioning is threefold: To regulate the temperature, to regulate the humidity and to remove, in the washing proce: the carbon and other particles sus- pended in the atmosphere. The attempt to produce ideal air conditions for President Hoover and his successors is in line with the coun- try’s long established policy of supply- ing safeguards against possible sickness of its Chief Executive. It will be inter- esting to observe the result of this move. The chances are, however, that the results of air-conditioning on human beings will be too general to be no- ticed. The race has gradually become immunized to many of the dangers of defective air, although it may have suf- fered in the meantime. But certainly, people living in our great cities have proved themselves capable of surviving ork in His Surroundings. under present conditions. With the higher primates, how- ever, it is different. The air of the jungle is alternately washed by rains and sterilized by the rays of the sun. Almost no carbon specks are suspended in the jungle atmos- phere, That a species of animal which has been accustomed for generations to such ideal condi- tions, should find death lurking in the millions of pounds of soot and dust which are continually suspended over every American city is not surprising. It is in the orang-utan, then, and the chimpanzee, the gorilla and ba- boon that the results of air condition- ing will show, if at all. And, if true, “jungle weather” can be consistently reproduced behind glass walls, and feeding can be accomplished with suf- ficient care, there seems to be no rea- son why the little babies of “Maggie” and “Marianne,” and their successors, should not survive in this country. One of the factors in the evolution of the science of making “synthetic weather” is the importance of humid- ity. All of us have said or heard someone say, “It's not the heat; it's the humidity.” When science began to work on the plan of improving hu- midity conditions the way paved for improvement in indoor air. First, science concluded that there are two extremes to humidity. One is evident on a day when we say the 3,000,000 POUNDS OF SOOT Professor H. H. Sheldon, New York University Physicist, Analyzing Dirt, Soot, Dust and Germs E. racted from the Air by a “Weather Machine” in a New York Theatre.

The other extreme is evident when, although the thermometer registers a fairly high degree of heat, we have a Science feels that it knows what proportion of humidity orang-utans chimpanzees and the rest of the mon keys need to maintain_their health And this is why Curator Brown and the rest of the nation’s zoologists reali; expect to raise Philadelphia’s two mos famous babies to maturity. 7 PN AN WA e s 3 | “Thar’s Gold in Them Thar Hills,” Said the Forty-Niner—It Took a Boy to Find It | HE gold rush of '30 is on! ‘Dig- gins” long since deserted are being reopened in the Mother Lode country of California.
