It will be seen how comparatlvolv safe mist be a gliip 

 with all the WHteMierht oells V, V, V. The mere pierc- 

 liiK of the outer sUell, eaffl.iient in itself to sink vessels 

 of the prosunt build, will uot injure a ship built in this 

 r. Tiie distance apart of tne inner am) outer plating 

 should be lictwccn two 

 and three feel, preferably 

 the latter. This method 

 of construction can be 

 need either for steumi'rs 

 or Biiilinir vessels, ami in 

 cither case the protection 

 is of the most perfect 

 nature which can prac- 

 tically lie used. 



Enough lias been said 

 clearly to demonstrate the 

 superiority of cellular 

 ships. Whether the dan- 

 ger menacing them be a 

 rocky coast, an approach- 

 ing vessel, or an opening 

 in I he seams of the plating, 

 so long as we have two 

 thicknesses of iron be- 

 tween us and the water 

 we rim rest in the cotu- 

 fortuble assurance that no 

 ordinary calamity can 

 cause our vessel to become 

 puiidenly unsea, worthy. In 

 advocating the adoption of 

 the cellular construction 

 for the transatlantic 

 steamers, it is not pro- 

 posed that an experiment 

 be tried, but simply that the 

 vicwsot sunn- of the most 

 eminent shipbuilders of 

 the world be adopted. 

 John Seott Russell has, 

 both in his practice and in 

 his great work on ship- 

 building, advocated most 

 strenuously the adoption 

 of double bottoms in ves- 

 sels of any considerable 

 siz". Sir William Foir- 

 bairr considers that the 

 cellular construction is the 

 only method which pre- 

 sents the maximum of 

 safety, and ho advises its 

 adoption. Others equally 

 eminent in all matters per- 

 taining to shipbuilding 

 predict that the longitudi- 

 nal framing combined 

 with an inner skin will 

 enable iron ships to meet 

 safely the dangers which 

 now are almost certain to 

 cause their destruction. 

 Haste to be rich alone delays the adoption of these im- 

 jirnvi nil-ills. The law may eventually do much, but more 

 <-an In- done In the pniilic by travelers and shippers of 

 freight not in med almve its value, by snnpiy refusing 

 to iiainiiMK those, lines which do not hold out as 

 an Inducement, at least for paeseneer traffic, the safety 



lifi'ordi-u I iv ocean steamers wilh double bottoms, which 

 Shall be a little better than egg shells. Thus can the, 

 pocket nerve he touched of those who, \\itli the light 

 of science and experience, for the sake of a saving 

 in lir.-t cost, seii'l everv year many thousands of souls 

 am..-s the broad Atlantic in ships whoso construction 

 violates the known rules of safety.
