is only another of the hundreds of
instances on record of the value of wireless telegraphy in saving life
on shipboard. Without Marconi's invention it is altogether probable that
the world would never have known of the nature of the Titanic's fate,
for it is only barely within the realm of possibility that any of the
Titanic's passengers' poorly clad, without proper provisions of food and
water, and exposed in the open boats to the frigid weather, would have
survived long enough to have been picked up by a transatlantic liner in
ignorance of the accident to the Titanic.

Speaking (since the Titanic disaster) of the part which wireless
telegraphy has played in the salvation of distressed ships, Guglielmo
Marconi, the inventor of this wonderful science, has said:

"Fifteen years ago the curvature of the earth was looked upon as the
one great obstacle to wireless telegraphy. By various experiments in
the Isle of Wight and at St. John's I finally succeeded in sending the
letter S 2000 miles.

"We have since found that the fog and the dull skies in the vicinity of
England are exceptionally favorable for wireless telegraphy."

Then the inventor told of wireless messages being transmitted 2500
miles across the Abyssinian desert, and of preparation for similar
achievements.

"The one necessary requirement for continued success is that governments
keep from being enveloped in political red tape," said he.

"The fact that a message can be flashed across the wide expanse of ocean
in ten minutes has exceeded my fondest expectations. Some idea of the
progress made may be had by citing the fact that in eleven years the
range of wireless telegraphy has increased from 200 to 3000 miles.

"Not once has wireless telegraphy failed in calling and securing help
on the high seas. A recognition of this is shown in the attitude of the
United States Government in compelling all passenger-carrying vessels
entering our ports to be equipped with wireless apparatus."

Of the Titanic tragedy, Marconi said:

"I know you will all understand when I say that I entertain a deep
feeling of gratitude because of the fact that wireless telegraphy has
again contributed to the saving of life."

WATER-TIGHT BULKHEADS

One of the most essential factors in making ships safe is the
construction of proper bulkheads to divide a ship into water-tight
compartments in case of injury to her hull. Of the modern means of
forming such compartments, and of t
