The Furnace-Room, where Carborundum is Made 131 "A great, dingy brick building, open at the sides like a shed." Taking Off a Crust of the Furnace at Night 135 The light is so intense that you cannot look at it without

with a crater at its summit, and blowing a magnificent
fountain of flame, lava, and dense white vapour high
into the air, and roaring all the while in a most terrifying
manner." Side View of the Solar Motor 155 Front View of the Los Angeles Solar Motor 159 The Brilliant Steam Boiler Glistens in the Centre 163 The Rear Machinery for Operating the Reflector 167 Trees Growing in Water at Professor Nobbe's

telegraphic communication. On that day there was sent by
Marconi himself from the wireless station at South Wellfleet,
Cape Cod, Mass., to the station at Poldhu, Cornwall,
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
workmen were hurrying to stow sufficient ballast to secure
it against a heavy sea, a storm forced the attending
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
