B'TS Bees belong to the order of lnsects called Hymenoptera Cgauzed, wlngedl They are the most ingenious workers of all the insects and they stand at the head of the lnsect series Over five thousand specles of bees are known They live ln hives and may be found ln all part f the world, especlally in the troplcs The two most common kind of bees are the Soclal Bees, and the Honeyb csCBumblebees and the stingless Honeybees of the troplcal zone! The Solltary Bees include the leai cutting bees and carpenter bees The Honeybees are noted for their skill 1n maklng honey whleh lS made from the pollen and nectar of flowers The nectar lS stored up ln waxed cells which are present ln every hlve An ordlnary hlve of bees make as much as two hundred pounds of honey ln a day, whlch proves that bees are the most efflclent devlce used in turning nectar into honey Bees use honey for food and lt In each hive of bees there may be found three K1ndS of bees They are The workers or undeveloped female, queen, a fully developed female, and the drone, or male bee Each of these bees has its own special work to do, therefore, all work together for the good of the hive The queen acts as the mother of each bee 1n the hive, which numb rs from 10,000 to 100,000 bees Che also lays all the eggs of the hlve, which may be as many as three thousand a day The worker bees gather all the nectar and pollen from flowers, fill all the combs, and care for the young or baby bees These worker bees work very hard because their stomachs are only about as large as the head of a pln, therefore it must flll and empty lts stomach more than flfty times to get a half thimble full of nectar The drones are incapable of gathering nectar and serve only one purpose whlch 1S of fertllizing the young queens As soon as the mating season is over, the drones are shoved out of their hives and allowed to starve The queens live as long as five years, the drones during one season, whlle the workers live only about five weeks Bees cause the cross pollinatlon of many plants The Honey bees whlch gather nectar for honey are the most important carriers of pollen They have two tiny cups on their hind legs to take pollen to the hive, but some cllngs to their bodles and is carrled to other flowers The nectar stays in the flowers to which it has been taken, thus causing cross pollination which is merely the transfer of nectar from one plant to the stamen of the other plant, then the new seeds develop in the new plant Bees are also often necessary for the production of a good crop Phyllis Maxwell '47 Biology an . . . . .

CHEMISTS Amadeo Avogadro, an Italian scientist, was born in 1776 and died in 1856, whlle he was professor of Physics in Turin He enun ciated the law that bears his name and thus laid the foundation for determining the number of atoms in a molecule of an elementary gas Avogadro showed the relation between the law of Gay Lussac and the atomic hypothesis of Dalton He assumed that the molecule of an elementary gas could be composed of smaller units, and that the relative densities of gases agree with the values determined by experiment Ernest Solvay C1839 19227 was born in Belgium He made prec tical a process for obtaining the carbonates of sodium directly from common salt by a precipitation method His scientific achiex ments brought him many honors and great wealth which he used gen erously in phllanthrooic and educational work He was promlnentln the political life of his country and was a member of the Belgian Senate Edward G Acheson, is the inventor of many important processes associated with the graphite and carbon compounds He is famous chiefly as the dlscoverer of carborundum, artificial graphite, and deflocculated graphite In connection with these industries he h s had a great deal to do with the development of electric furnaces He invented graphltized anodes, which are much more durable than carbon electrodes in electrolytic furnaces To meet the need for a highly refractory material he invented siloxlcon, a compound of temperatures He was awarded the Perkins Medal of the Society of Chemical Industry in January, l9lO Sir William Ramsay fl852 19167 was born in Glasgow, Scotland He was known as a remarkably, skillful experimenter He shared with Rayleigh the honor of the discovery of argon This element, although present in the atmosphere to the extent of almost one per cent, had escaped detection because of its chemical inactivity Further works by Ramsay indicated the presence of other previously undiscovered gases in small amounts, in the atmosphere, and showed that helium, formerly known only as a constituent of the sun, was given off by certain minerals With Soddy, he found that hellum lS one of the discomposition products oi radium Ramsay was awarded the Nobel Prize in 190A Robert W Bunsen 11811 18997 was born in Gottingen and edu cated in its university He was professor in several German Un1 versities At Heidelberg he had a career of nearly fifty years as a great teacher and brllliant investigator His researches led to the acceptance of the idea of radicals existing in com ounds Many of his simple and efficient laboratory devices, are in use today, notably the Bunsen burner Bunsen may be regarded as the founder of modern gas analysis His greatest vork was the invention, with Klrchhoff, of the spectroscope This instrument is useful in the detection of known elements, and has led to the discovery of new ones By its means Bunsen found calclum and rabidium ' ll I 1 . 1 .
