stevens 5 the final lacrosse championship game was played on saturday on the st george cricket grounds ajfc hoboken between lehigh and stevens and resulted in a victory for the latter this being the first championship game that stevens has won during the past four years johns hopkins again holds the inter-collegiate championship of the united states with stevens second and lehigh third the coaching of mr kirk was seen in the play of the stevens team both in the attack and de fense their tipping was quick and snappy and their shots for goal swift and well directed our attack although they had the ball as often as their oppo nents were unable to score this was partly due to the work of the stevens goal keeper who made several pretty stops and to the bunching of the stevens de fense in front of their goal and partly to the inaccurate shooting of our attack several clear shots going wild the game was called at 3.30 and for the first ten minutes the play was very even the ball going from one end of the field to the other finally the stevens attack by a series of quick passes sent the ball into the net for the first goal dur ing the next ten minutes lehigh had the ball most of the time and made three shots at goal all of which were stopped by the stevens point and goal keeper stevens then got the ball and after an un successful attempt at goal lost the ball which went to lehigh's at tack but it was quickly returned and stevens scored their second goal a few minutes before the half closed score stevens 2 ; lehigh 0 in the second half lehigh played a faster.game and her attack were very successful in passing the ball on the sides of the goal but lost it whenever they attempted to work it in front of the goal the defense although they played a hard game allowed three more goals to be scored making the final score stevens 5 lehigh 0 the lineup follows : lehigh positions stevens starkey goal layat wor thidgton point campbell symington cover point wuchter maeder first defense scamell reese second defense sanders gummere capt third defense . mcdonald capriles centre jennings rovelo third home scott abbott second home meyers young first home brooks digby out home clarke martin in home devine referee martin stevens 93 judges of goals symington lehigh robinson stevens time two thirty-fly minute halves timekeepers rittenhouse lehigh bar low columbia goals scott 2 clarke 3 divine «. baseball psi u vs sigma x today college lecture the last of the series of college lectures was delivered saturday morning in the physical labora tory by professor franklin he spoke on " wireless telegraphy " in part as follows : telegraphy consists in producing a physical disturbance at a point and then the disturbance passes to to another point where some form of receiving instrument reproduces it in telegraphy by means of wires the disturbance is confined to a certain path and the loss in intensity is therefore very slight this is not the case however in wireless telegraphy the dis turbance at the sending station passes out in all directions through the agency of air water or lumini ferous ether and with increase of distance the intensity fa ls off very rapidly necessitating a great amount of energy at the point of disturbance to communicate through long distance the mechanical means of pro ducing signals at distant stations — stress motion and rotary effect are analagous to the electrical means employed in all these the intensity varies inversely as the cube of the distance in the periodic disturbance producing longer wavtf motion the variation in den sity is inversely as the square of the distance when wave lenghths from a dis turbance are small they are easily broken up by the mist and particles of dust hence it is of the greatest importance that the waves be suf ficiently large hertz waves vary in length from six inches to five feet the simplest means of wireless telegraphy is the pnssingof a cur rent through a coil of wire pro ducing a magnetic field in the whole surrounding space and re producing it at a distant station by some receiving apparatus the intensity here varies also inversely as the cube of the distance it has been estimated that a coil of sufficient intensity to tele graph across the atlantic oc-an would need to be one hundred miles in diameter and a coil to receive the communication at the other end would have to be just as large in making use of water in the transmission of the disturbance as from one ship to another the following method is employed : bach ship has a buoy in circuit with it trailing behind the message is sent from the ship to its buoy and the lines of force pass out in all directions and strike the buoy of the other ship con veying a reproduction of the origi nal disturbance to that ship the method generally employed is the production of stress at a point in the ether and the reproduction by a receiving apparatus at another point for long distance the longer wave form of disturbance is l/h«rilijrrl ulnlvlikoll 1 south bethlehem pa tuesday may 23 189 no 57 the brown and white vol vi calendar thursday may 25 baseball le high vs manhattan on lehigh field friday may 26 at 7.15 p m meeting of the civil eng.neer ing society in the physical laboratory at 4.80 p m choir rehears al in the chapel saturday may 27 at 3p m lacrosse lehigh vs toronto on lehigh field sunday may 28 at 6.15 p m meeting of the christian asso ciation in christmas hall tuesday may 30 — at 3 p m r baseball lehigh vs univer sity of pennsylvania on le high field lacrosse lehigh vs college of the city of new york at new york notices analytical chemistry the organic and quantitative laboratories will be closed for the year on saturday may 27 at 6 p m the qualitative laboratory will be closed the day following the last examination in qualitative analysis class day orators at a meeting of the senior class held on wednes lay morning the following men were selected as class dij orators : prophet j w grace poet rainey ;

lehigh 43 the second annual track and field meet between lehigh and lafayette held last saturday on lehigh field resulted in a victory for the lafayette team by a margin of two points all of the eleven events were well contested and were with few exceptions very close ; in no event did either of the teams get first second and third places by taking the first two places in each of the two hurdles lafayette scored fourteen out of a possible sixteen points and this more than anything else perhaps explains lehigh's defeat in the running broad jump lehigh made seven points and likewise in the half-mile run ; in the balance of the events the honors were more or less evenly distributed first place counted for five points second tor two and third for one in the sixteen-pound hammer event butler of lefoigh made a throw of ninety-five feet and thus broke the lehigh record made by c h detweiler in 1890 by one foot and seven inches james in the running broad jump came within three inches oi the lehigh record made in 1895 by g l yates ot 97 the 100 yards dash and the 120 yards hurdle were made in very fast time no time is given in the mile run for the reason that owing to some mis understanding the race lacked one lap of being a mile the event however was allowed to stand as it was run in individual work ely of lafayette and grubbe of lehigh each with two firsts and two seconds to their credit did the best chidsey and carey of laf ayette and tobleman and lindley of lehigh all secured a first and a second place 1 the fine work and excellent form of grubbe cannot be too heartily commended after taking second place in the 220 yards dash he finished first in the half mile run which immediately followed and which was one of the best races of the meet tobleman is also deserving of special mention for the remarkably strong finishes which he made in the mile and half-mile events considering the state of the weather the crowd which turned out was a fair one the games occupied in all about three hours following is a list of the starters and winners in each event together with the officials of the meet : summary op events 100-yard dash lehigh — j j reamer w b grubbe a lindley lafayette g w hagney e s ely w h peters won by ely 10 1-5 sec grubbe second ilagney third continued on second page
