Ing point Of view an undertaking of
this sort would not be alluring.
But it may be that the wreck of the
ship is not in this unpromising pre-
dlcament. How is the Denver inventor
to satisfy himself upon this point?
Mr.. Smith has planned as an auXil
larry type of submarine boat which is
to be strong enough to withstand the
deepest submergence required for the
reaching of the Titanic wreck. In this
direction the inventor is practically
celebrating on the work of the noted
Italian submarine engineer Signor
Pine.
The latter designed type of globu-
lar submarine, which, because of its
particular form and the nature of its
fabrication, would stand up under the
crushing stresses of very deep sub

According to Mr. Smiths plan,
these submarine auxiliaries will be
lowered from big wrecking steamers
and will obtain their limited propulsive1
energy from the electric power plant
Of the surface craft. Their purpose
will be two fold: That of locating and
exploring externally the shattered
wreck, and to assist in guiding and in
