              inter-class meet results promise successful season the results of the inter-class track meet held on wednesday afternoon were decidedly encour aging most of the men showed up very well and there are very good prospects this year of a track team which will do credit to the college the weather was not suited to the event and owing to the dampness of the track and a strong wind the time was not as fast as it would otherwise have been the juniors easily carried the honors with seven first places making the second consecutive year that the class of 1911 has swamped its competitors in this annual event one of the features of the meet was the pole-vault in which graham m.i took first place clearing the bar at 11 feet 1 inch all the races were close and excit ing and the way in which the men ran showed the result of hard work and training the score 1911 59 points 1910 31 points ;

some photographs of the mines and various mills taken by mr henry were exhibited the society was fortunate in se curing mr w l cumings head geologist of the bethlehem steel company to speak on " magnetic surveying mr oumings experi ence in various parts of the united states cuba and venezuela enabled him to give a very practical and interesting talk on this important branch of engineering work the general surveying in the lake superior region most of which is done not with a transit but simply with a compass was discussed in the introduction to his talk the men who do this work develop a wonderful accuracy of pacing and power of observation which makes them very desirable on the united states geology sur veying corps mr cumings brought along several compasses of the brooke type which are used in this work together with a dip needle and some magnetic ore he gave a demonstration of the method of us continued oil third page lehigh university south bethlehem pa friday may 13 1910 mining society meeting vol xvii juniors win track meet the planet lehigh i mr reynolds of the math dept works up elements of its orbit the eev joel metcalf of taun ton mass discovered by photo graphy about the first of december 1909 a minor planet its position was photographed at four dates prior to february 191.0 these positions were sent to prof ogburn and under his direction mr reyn olds of the dept of math has worked up the elements of the orbit of the newly discovered body in recognition of his work mr metcalf has kindly permitted the new planet to be called lehigh circulating about the sun in the interval between mars and jupiter there is a large number of these small bodies they range in size from 500 miles to 10 or less in diameter as lehigh is 125 magnitude at opposition that is when the earth is nearest to her she is probably not more than 25 or 80 miles in diameter and possibly smaller her year is equal to about 5.2 of our years it would readily seem as if one could travel around her on a bicycle or an automobile if there in three or four hours but such a velocity would cause one to leave the planet and go off into space on account of the cen tripetal force a 150 pound man would weigh about (> oz athletics would be wonderfully enhanced kiley would clear the bar at 1850 ft and graham would vault a full 4,000 a jump taking 11 minutes wells would put the shot around the world and wolfram would bat th<3 ball to infinity even with that his home run would be a little difficult for it would be hard to get up enough friction to carry one around the diamond a wildly pitched ball might become a moon for the planet or even go off into space and become a satellite of the sun or some distant star records in dashes would hardly be lessened since a velocity greater than 10 miles per hour would raise the runner from the surface and if by any means he could get up to more than 15 miles per hour and be re leased he would pass off on a hyperbolic orbit to infinite space many other such things might be said of this little celestial body but its chief interest lies in the fact continued on third i'agc trunk line electrification w s murray 95 addresses the electrical society the last meeting of the electrical engineering society for the college year was held in the physical laboratory on tuesday evening at 8 o'clock a large number of guests attended including john fritz dr drinker e p stevens president of the lehigh valley transit company w s murray 95 and a large number of civils and mechanicals the program was opened by w s murray chief electrical engineer of the new york new haven and hartford railroad who gave a talk on " trunk line electrifica tion by means of lantern slides mr murray described fully the construction and operation of the new haven's line and explained the many difficulties encountered in its building the power is sup plied by single-phase alternating current at 11,000 volts ; it is col lected by a shoe mounted on a pantograph which slides under the overhead wire this overhead wire is supported by a steel wire in the shape of a catenary and this in sures a level wire without sags the overhead steel bridges which take the place of poles are of a substantial nature and are built to withstand heavy strains a comparison of old and new 1 methods was made together with a descrip tion of an experimental line just completed mr murray then des cribed some of his experiences and gave some advice to college men which dr drinker highly ap proved the election of officers followed and resulted as follows : president 11 11 fithian vice president c w hendricks ;
