Converting an Automobile into an 

 Apartment 



YOU can go for an automobile tour 

 now and carry your apartment 

 with you in a neat-looking box-like 

 contrivance which fits on the back of 



and other comforts to be had at home. 

 The automobile-telescope apartment 

 is the invention of Gustav de Britteville 

 of San Francisco, who uses it on business 

 tours into the country. 



How To Make Spirit Photographs 



PRINT from ordinary negatives in the 

 usual manner on printing-out paper, 

 then fix the prints in a solution of i oz. 

 hyposulphite of soda and 8 ozs. of water, 

 and wash them thoroughly. While still 

 wet, immerse them in a saturated solu- 

 tion of bichloride of mercury until the 

 image disappears; then wash thorough- 

 ly. Be very careful, as bichloride is very 

 poisonous. Soak some clean blotting- 



There is very 

 little left to 

 desire in the 

 way of an 

 apartment if 

 one has this

 taken off or put on in fifteen minutes. 

 The shell or case of the telescoping 

 apartment is three feet and four inches 

 long, as wide as the automobile, but not 

 as high at the highest point as the 

 automobile top. The roof of the 

 "apartment" has a gentle slope. 



\nU) this small space are, fitted a 

 comfortable double bed in an electric- 

 ally-lighted berth with a tempting book- 

 shelf over the head of the bed; a

 bath e(iuipment which includes a ten-

 minutes b y 

 an amateur 



paper in the hyposulphite of soda solu- 

 tion and allow it to dry.

 pear, cut a piece of blotting-paper the 

 same size as the prepared print, and 

 moisten it; then hold the apparently 

 l)lank piece of pajx'r in contact with it. 

 The photograph will come out gradualy- 

 clear and plain, and if washed thorouglh
