Steam-Heat the Wallpaper and then 

 Tear It off in Strips 



REMOVING old wallpaper from a room 

 is always a tedious job; but a steam- 

 heating appliance has been invented by 

 Nathan Rubenstein which does away with 

 the inconveniences of other methods. The 

 appliance, first of all, can steam 

 heat the paper to a very high 

 temperature. The steam slightly 

 moistens the paper at the same 

 time, so that an entire strip can 

 be peeled off at once. 



The steam, generated in a 

 boiler by a gasoline burner, is 

 conveyed by a hose to a sheet- 

 iron block which is brought flat 

 up against the wall. The block 

 is perforated and the holes are 

 covered by a cloth pad. Some of 

 the steam which is fed into the 

 block will penetrate through 

 the holes and slightly moisten 

 the cloth. When the hot moist 

 cloth is guided slowly over the 

 wallpaper, the heat cracks ofif 

 the glue, the moisture helping 

 the process, and the paper can 

 be readily skinned off without 

 the usual slopping. 



Measurements of the Valleys 

 of the Deep 



A MOST peculiar fact about the oceans 

 of the world is that the largest depres- 

 sions are to be found near the coastlines. 

 The three largest of these are all in the 

 Pacific, two of them being near island coast- 

 lines. The "Swire Deep," just off the 

 Philippines, measures no less than thirty- 

 three thousand feet from the surface of the 

 ocean to the bottom. This is just three 

 thousand feet deeper than Mount Everest, 

 in Asia, is high. The "Aldridge Deep" in 

 the South Pacific ranks next to this, being 

 nearly thirty-one thousand feet deep. The 

 third is the "Tuscarora Deep" near Japan, 

 which soundings indicate to be twenty- 

 seven thousand, six hundred feet in depth. 

 This would then make the bottom of the 

 Tuscarora Deep over two and three-eighths 

 miles below the average level of the bottom 

 of the ocean.

The Newest Barrel for Storing Dry 

 Stuffs Is Collapsible 



O picnic is complete without a col- 

 lapsible aluminum drinking cup. The 

 latest adaptation of the idea assumes the 

 form of a collapsible barrel or cask for pack- 

 ing or storing articles such as nails, horse- 

 shoes, vegetables, or anything that does not 

 require a waterproof receptacle. 



The barrel, when flattened out, may be 

 stored in any convenient nook or corner, or 

 on a shelf and will take up little room. To 

 open it out for use it is necessary 

 only to pull out both ends. There 

 are five sections ordinarily, al- 

 though the number of sections is 

 not arbitrarily limited. 

 These sections lock auto- 

 matically when they are 

 pulled out into position, 

 so that when the barrel is moved 

 or rolled about there is no danger 

 of their collapsing of their own 

 • accord. 



In the head of the 

 barrel is a panel which, 

 besides reinforcing the 

 head, is used to receive 

 addresses when the barrel 

 is used for shipping pur- 

 poses, or for information 

 to clerks in the shop or 

 storage house concerning 

 the contents, or for ad- 

 vertising matter.
