AnOtsworthy marine inventor hiss been brouehtfor

the plan consisting In having telescope iron matches,
90 arranged that the pressure of water from below
would. in such a contingency. bind them more tightly
In their places, precludins the possibility OF the wa.
ter rising above the nrst deck, which forms q plat
form or horizontal bulkhead. preventing the ship
from hinking and water from reaching tho cargo from
above. The improved construction here involved in.
sures also moro effective ventilation. thus preventing
the cargo from heating and sweating. and, rs such
matches are capable OF being Theoretically sealed, tho
valuable advantage OF the naturalization OF nro ia
realized. II is urged tn lat the practical effect resulting
from matches Of this character viii be TO multiply
the water.tight divisions of a ship in proportion as
t~he'number OF decks are to bulkheads; a ship, for In.
stance. with eight bulkheads and three decks would
at present have only mine water.tight compartments
with wooden matches. but with the improved matches
and decks would have twenty. nve compartments.
Tho attention OF inventors has lately been emphati.
cnlly called to the necessity of greater security in tho
construction of elevators and their operative mech.
anisms, and this greater safety Ia to be considered, ac-
cordihg to the opinion of experts and of common OBJ
servation ~ we'll, from the point Of view that the
dropping OF the cage ia tho most serious as we'll rs
the most frequent form OF elevator accidents. IL 10
reasoned that the difnculty docs not lie in a deficiency
OF cable strength. II being easy 20 determine the
maximum load and the strength OF the wire strands.
Nevertheless. cables break when there IL no apparent
cause. the safety OF pnssengers being Tina dependent
upon IN 'mmeuiate action OF tine catches put on Tor
the purpose Of stopping the car at any point in the
shaft. theoretically, II ia argued by q writer in tho
Providence Journal. nothing can prevent tho throw.
