and inside of two hours she was in deep water. It was somewhat rough in crossing the bar 

 and, as the vessel rolled, we lost a good deal of the air, and this illustrates the weak spot in 

 the compressed-air means of expelling water. In the case of damage by collision the injury 

 usually extends both above and below the water-line, and where that is the case the com- 

 pressed air cannot be applied. Where the damage is in the bottom the system is ideal. 



Mr. Alden D. Welch suggests the use of flue gases as a protection against fire. He had 

 in mind, no doubt, Dr. Marker's system, which is very effective against fire in holds. Flue 

 gases, however, destroy life as well as fire and have been very effective against rats on ships, 

 yet the water system of fire protection must be used in living spaces, and the system I pro- 

 pose gives a splendid opportunity to confine its use to the particular six)t where a fire has 

 started without causing any alarm in other parts of the ship.
