The barber's client looked depressed, so the barber told him, "Cheer up. I knew a guy who owed $5,000 he couldn't pay. He drove his vehicle to the edge of a cliff, where he sat for over an hour. A group of concerned citizens heard about his problem and passed a hat around. Relieved, the man pulled back from the cliff's edge."
"Incredible," said the client. "Who were these kind people?"

Five-needle telegraph demonstrated

In 1837, the five-needle telegraph was demonstrated by English inventors, Charles Wheatstone and William Fothergill Cooke. They ran a six-wire telegraph line 2.4-km from Euston to Camden Town along the Great Western Railway Company railway track. They successfully transmitted and received messages. Wheatstone provided the technological skill and is better remembered in the history of the telegraph while Cooke had the business acumen. This first patent (1837) was impractical because the code used simultaneous combinations of five keys, and so was rather cumbersome, limited to only twenty letters (J, C, Q, U, X and Z were omitted). By 1845, they patented the more important single-needle electric telegraph.«
