composed chiefly of members of the faculty and upper classmen heard the lecture delivered by dr a e kennelly of philadelphia before the electrical engineering society on friday evening the lec ture was beautifully illustrated ap propriately worded and admirably suited to a clear understanding of the audience after the introduction of the speaker and the announcement of the subject " long distance trans mission of power by alternating electric currents dr kennelly proceeded with his lecture a few well chosen sentences set forth the importance of the subject from a financial point of view from this time the lecture was clearly illustrated by stereopticon views which contributed largely to the ease of explanation as well as ease of understanding the open ing view showed the niagara falls as they now appear in their grandeur wasting the energy of nearly seven million horse-power by the fall of about 275,000 cubic feet of water through a distance of 216 feet in one second the great est part of this energy is now being lost but it is hoped that at some time it may all be utilized illustrations followed showing niagara river suspension bridge and the location of the tunnel through which the water flows at the rate of twenty miles per hour the tunnel which is lined through out with the best hard burned brick will carry an amount of water at a sufficient speed to develop one half million horse power the power house arrangement capacity and vol 111 no 2 the brown and white lehigh university thur dec sday frii dec ay . 13 satu dec jtday i 14 !
