telegraphic communication. On that day there was sent by
Marconi himself from the wireless station at South Wellfleet,

England, a distance of 3,000 miles, the message—destined
soon to be historic—from the President of the United
States to the King of England. Preparing to Fly the Kite which Supported the

a Violent Storm 254 Just after the cylinder had been set in place, and while the

steamer to draw away. One of the barges was almost
overturned, and a lifeboat was driven against the cylinder
and crushed to pieces. Robert Stevenson, Builder of the Famous Bell
Rock Lighthouse, and Author of Important
Inventions and Improvements in the System
of Sea Lighting
