THE WORLD'S ADVANCE 



quently it is clear that burglars will never 

 succeed in melting open a safe made 

 from the new steel, because, aside from 

 the great outlay of time needed for this, 

 they could not bring with them the great 

 quantities of gas, since four steel cans 

 weighing 154 pounds apiece would be re- 

 quired. 



The steel plates are very hard and can- 

 not be bored, consequently the holes for 

 the screws and rivets must be made at 



seat back, support the cushions which 

 are taken from the seats directly beneath 

 the bed. In this manner there is im- 

 provised a real spring bed which is roomy 

 enough for two people. Except for the 

 slight inconvenience of climbing into this 

 new kind of an "upper berth," this form 

 of camping out while on long trips in- 

 volves no discomfort. The bed can be 

 made up in from three to five minutes 

 and when taken down is folded into a

 lose its hardness by annealing and by 

 reason of its tenacity can be bent to a 

 certain degree. 



CAMPING OUT IN AN AUTO 



When he goes on long auto trips a 

 Washington state inventor "camps out" 

 in a bed swung from the top of his auto- 

 mobile. The bed is not merely a ham- 

 mock, but utilizes the seat cushions as 

 well. Rods, fastened over the backs of 

 the seats and extending from the top of 

 one seat back to the top of the other 



compact bundle that does not take up 

 much room in the automobile. 



A NATURAL HEATING PLANT 



It is now said that hot water provides 

 the perfect heat. The stoker of the heat- 

 ing plant, however, may now and then 

 entertain the idea that there is as yet no 

 universally perfect way of making the 

 water hot. It is of interest to know that in 

 at least one place on the earth Nature has 

 been so lavishly kind as to provide and 

 run, by her own efforts and without cost 

 to the user, a hot water plant, and that
