dow experiencing the annoyance of 

 glare. But, as suggested earlier, if the 

 observer might step around lo the side 

 of the window and view it through a 

 hole knocked in the wall, there would 

 be glare a-plenty and a view of the 

 light sources themselves, too. The rea- 

 son is obvious. When the observer 

 stands before the glass in front of the 

 window, the direction of vision cor- 

 responds to the direction in which the 

 light travels from its ^sou^c'o to the* 

 goods. But when the observer steps 

 round to the side of such a windo"- f- '' 

 views it through a hole in the wall, the 

 direction of vision is across that of the 

 line of light travel. Also, if the ob- 

 server's position be far enough around 

 to the side, the line of vision then is 

 almost directly into the light sources.

That is, in effect, the condition which 

 obtains with regard to the corner win- 

 dow; the condition is, if anything, even 

 more extreme. With the regular win- 

 dow it frequently is to be observed 

 that the light travel is all from one 

 general direction, from above the win- 

 dow, whereas the corner window cannot 

 be acceptably lighted unless there be 

 light coming from at least two direc- 

 tions, because the display in tlie corner

window is set up to face two ways. 

 That is to say, part of the display 

 faces one window and the rest faces the 

 other window. Obviously, both halves 

 of such a display cannot be adequately 

 illuminated by a light coming only 

 from one direction.

That can be understood by imagining 

 two objects placed in a eorner window^
