THE ENGLISH SPARKOW AS A PEST. 



past summer caught 300 sparrows in six weeks. Its usefulness in a 

 city garden has already been referred to under " Localization." 



The essential parts of this trap are: (1) A half funnel leading 

 into (2) an antechamber, which ends in (3) a complete funnel lead- 

 ing into (4) a final chamber. It is made of woven-wire poultry 

 netting of f-inch mesh and is reenforced around the open end and 

 along the sides at the bottom by No. 8 or No. 10 wire, which is used 

 also arounqj the aperture for the door and around the door itself. 



FIG. 13. Pattern for first funnel of a trap to be 36X18X12 inches. 



The angles between the first funnel and the walls of the antechamber 

 are floored with netting, and the final chamber is floored with the 

 same material. The accompanying drawings will enable anybody 

 handy with tools to construct one of these traps in a few hours. 

 These plans are for a trap 3 feet long, a foot and a half wide, and a 

 foot high. At ordinary retail prices the cost of material will be 

 about 70 cents. Paper patterns for the two funnels can be made by 

 first drawing the concentric circles, as shown in figures 13 and 14, 

 and then laying off the straight lines, beginning with the longest.
