TELEGRAPH KEY USED TO MILK COWS
GAINESVILLE, Fla., July 23. Cows were milked by telegraph at the Florida experimental station here. It was another case of necessity mothering invention. The milking machine broke down. A spring in the pulsator was broken. The part had to be ordered from New York. Meanwhile there were 30 cows to be milked, then the campus electrician took an ordinary telegraph ticker and connected it with the. pulsator so that it would make and break the current that alternates the suction. By operating the ticker at a speed of 45 to 4B times a. minute, just as though he were sending a. message over the wire, lie caused the millring machine to do its morning work nicely.
