 to which they may be applied, and their utility as life-preservers, 

 are alluded to in the description of one of them, fig. 4, as a pon-

 durable, and, arranged as there described, is perfectly safe as a 

 life-preserver, and also useful as a mattress, bed, or cushion ; but 

 considering its bulk, how far it may be applied or made prac- 

 tically useful for garments, in comparison with other things that 

 are hghter and more convenient as garments, is a question. 



FIREMEN'S CAPS 



Are manufactured by the combination of caoutchouc whale- 

 bone and vegetable leather, much in the same manner as the 

 mihtary caps, described in Chapter . This cap is made so 

 as to unite all the properties that are desired in firemen's caps, 

 being so constructed as to ward off accidents, without being too 

 heavy or unyielding. See plate , fig.
