CAPE AND PONCHO BEDS. 263 



VENTILATED PILLOWS. 



The objection to gum-elastic pillows, on account of their 

 warmth and rolling motion, is almost wholly, if not entirely re- 

 moved by the invention represented in plate xxvii., fig. 12. When 

 folded, it is used for a pillow ; when opened, as represented, 

 plate , fig. , it is designed to be used as a life-preserver 



when required. This may be considered one of the safest kinds 

 of life-preservers, especially when stuffed with cork or curled 

 hair, on account of affording protection from injuries to the 

 person. 



BEDS. 



The air bed, represented by fig. , plate , is one of the 



articles first made of the Mc Intosh manufacture ; and when 

 made of the plated fabrics, after the method described, page , 

 is the cheapest article of air beds ; although the same pattern, 

 represented by fig. , with a tube for each compartment, is 

 much more secure from being damaged, and is not much more 

 expensive. 



CAPE AND PONCHO BEDS. 



These are manufactured of the improved air and quilted 

 fabrics, described Vol. I., page 



When each row of compartments or cells in this poncho, 

 which are usually from thirty to fifty, are inflated by a separate 

 valve tube, at least two-thirds of them must be damaged before 

 the bed will be unsafe in the water.
