Each evening bird-lover Tom stood in his backyard, hooting like an owl. One night, an owl called back to him. For a year, the man and his feathered friend hooted back and forth. He even kept a log of the "conversation."
Just as he thought he was on the verge of a breakthrough in interspecies communication, his wife had a chat with her next-door neighbor.
"My husband spends his nights... calling out to owls," she said.
"That's odd," the neighbor replied. "So does my husband."

Alfred Brandt

Died 29 Nov 1899 at age 53 (born 3 Sep 1846).German civil engineer whose major achievement was enabling construction of the 12.5 mile (20-km) Simplon Tunnel, a major tunnel through the Alps between Italy and Switzerland. As a young engineer working onboring the St. Gotthard Tunnel between Italy and Switzerland, he learned about the difficulties involved, and the use of pneumatic drills and blasting. A hydraulic drill of his own design was used to drive theArlberg Tunnel between Austria and Switzerland. To dig the Simplon Tunnel, he innovated by driving two separate tunnels 55-ft (17-m) apart, connected by crosshatches to provide for ventilation, temperature control and a circuit for debris-removal trains. He died early in the project, from the strain of overworking himself.«[Image: Simplon Tunnel during construction, model]
