 is so big 

 and bulky 

 that a spe- 

 cial steel 

 framework 

 is necessary to keep it in shape. Turning 

 one page is like pulling up a trap door, only 

 the page is much lighter than a door. On 

 the other hand, the cover of the Bible, 

 which appears very distinctly in the ac- 

 companying photograph, is heavy. It 

 weighs as much as twenty good-sized books. 

 Twelve thousand persons have been en- 

 gaged in preparing the Bible. Perhaps a 

 hundred thousand will have helped before 

 it is completed. 



A Spring Big Enough for an Auto- 

 mobile Two Blocks Long 



AN automobile spring forty-five feet 

 l long is used by a Seattle factory as an 

 advertising sign. It is built of the same 

 materials as an ordinary spring, and the 

 workmanship is as accurate as in a spring 

 of the usual size. If put to 

 actual use the spring shown

 thousand persons have been engaged in preparing it 



ten times that of the ordinary pleasure car. 

 At the present time the spring occupies 



a position above the roof of the factory.

 it. When 

 asked for

 being made,

 "For a car 

 to carry the 

 man who 

 wore the

 boots." 



Leave the Gathering of Mushrooms to 

 an Expert Who Knows Them 



ACCORDING to specialists in the 

 ±~\ United States Department of Agri- 

 culture, there is no simple and infallible 

 test for distinguishing between edible and 

 poisonous mushrooms. The only safe mush- 

 rooms to eat are those that have been 

 gathered by a collector who knows his 

 business. 



The most common edible mushroom is 

 the Agaricus campestris. Its cap is fleshy 

 and hemispherical at first but later becomes 

 expanded and nearly flat. It is smooth and 

 light brown or white in color. The gills are 

 white at first, later pink, and finally a 

 blackish-brown. The stem is stout, smooth 

 and furnished with a ring. It is readily 

 recognized ; but before the gills turn color it 

 might be confused with the 

 Amanita, a poisonous variety.

The gills of the 

 Amanita remain 

 white. The safe 

 rule is to gather 

 only those with 

 colored gills.
