It is hoped that the attention of manufacturers will be 

 attracted to the advantage of introducing this life-saving 

 mattress into the marine service ; and that the importance of 

 its use on board ship will be generally recognised, and lead to 

 the establishment of the industry. Our river craft and sailing 

 boats more especially should be provided with it ; and in 

 these the mattresses could be utilised as cushions, and so be 

 immediately available when necessity required in case of 

 disaster.

 OF TASMANIA. 



By Lieut. C. E. Beddome, I.N.

 Tasmania than any one.
