these should be dovetailed so as to leave no 

 cracks through which any daylight may creep. 

 If our house is wired for electricity, it is easy to 

 run a wire to this room, and it makes by far the

 any other. Otherwise we can get our light by 

 cutting a square hole in one side of the room and 

 placing a lamp upon a bracket outside of the 

 hole. This hole should be covered with several 

 thicknesses of ruby cloth and orange paper, for 

 the least white ray in the light that strikes the 

 plate will inevitably fog it. The light, by this 

 arrangement, will be sufficiently strong for all 

 practical purposes, and by keeping the lamp out- 

 side it will not heat the room as it would were it 

 inside. 



If we can have running water in the room we 

 will find it a great convenience, but it is not nec- 

 essary. A plentiful supply of water, however, is 

 requisite in order that we may have entire cleanli-
