Duct Tape & Onwards

An old man is sitting on his porch when he sees a young boy walking down the street dragging something behind him. He calls out to the boy, "Hey son, what you got there?" to which the boy replies, "It's duct tape, I'm gonna go catch me some ducks." The old man laughs and he calls out, "You fool, you can't catch ducks with duct tape!" The little boy laughs and continues on his way, returning a few short hours later, and behind him, he is dragging 8 ducks, all wrapped up in the duct tape. The old man can't believe his eyes.

The next day, the old man is sitting on his porch again and along comes the little boy dragging something behind him. When the old man asks what he's got this time, the boy replies, "It's a spool of chicken wire, I'm going to catch some chickens in it." Well the old man begins to laugh quite hard, telling the boy, "You fool, you can't catch chickens with chicken wire." The boy laughs himself, and says back, "That's what you said about the duct tape," and he continues on his way, with the old man laughing like crazy. A few hours later the old man is surprised to see the boy coming back, and even more shocked to see that behind him he is dragging 10 chickens, all tangled up in the chicken wire, he can't believe his eyes again.

The next day, the old man is sitting there wondering what the little boy will be up to next, and sure enough he sees him coming down the street with something in his hand. He calls out to the boy, "Hey son, what you go there today?

" The boy responds, "It's a pussy willow." The man then replies, "Hang on son, I'll get my hat!"

Transpacific cable

In 1903, the first cable across the Pacific Ocean between Hawaii, Midway, Guam and Manila was completed and spliced at Manila, Philippine Islands. After testing, the first official message was sent the next day. The first section of the cable across the Pacific Ocean between San Francisco and Hawaii had already been established at the beginning of the same year, with its first official message sent on 1 Jan 1903. That technological event ended Hawaii's isolation by connecting it to the mainland U.S. and the rest of the world. The cable was a mainstay of communications into the early 1950s when newer technology rendered it obsolete. (The 1902 all-British telegraph line from Canada to Australia and New Zealand was the first line to cross the Pacific Ocean.)
