 as to catch the flies as they enter or leave through the window. It 

 is adaptable to barns which are fairly free from cracks or other places 

 where flies may enter. It may also be used on windows of buildings 

 where foodstuffs are prepared and where flies endeavor to enter 

 through the windows or escape after having gained entrance through
