A Warning to Fishermen
W11ILI-: lisliinK ill a small Pennsylva- nia stream the l^ev. W. P. Perry was killed al- most instantly when the steel rod hi' was holdint; became entangled in high-tension transmis- sion wires over his head. He was wading in the stream at the lime and whipping tliewalerin till-
��usual way. With no thought of the live wires he made a cast with the line and there was a blinding flash. The current of twenty thousand volts leaped down the rod, coursed through his body, and killed him before he could make an outcry.
This is said to be the first instance on record of the death of a man under such circumstances. During severe winter storms it is not infrequent to hear of electrocutions, due to fallen live wires hidden in debris.
Expending Four Tons of Energy in Playing the 'Cello
ASIAIPLE air pla>ed on the \-iolon- cello calls for a total expenditure of energy equal to two and three quarter pounds per note or more than four tons of energy for the single selection. This statement is vouched for by Professor Poffenberger, of Columbia Universit>-, who made some experiments in his laboratory with the aid of the famous Dutch 'cellist Michael Penha — experi- ments made to determine the amount of sheer physical strength recjuired to play the violoncello in the style of a great artist . A special apparatus is necessary to conduct the tests. Against the surface of a revolving carbon cylinder is sus- pended a chalked point which is actuated by a slender wire attached to the musi- cian's finger. At each pressure the tension vibrates along the communicating con- nection and records the energy expended.
