16. Method of catching the Tetrao Tetrix (black Grous) in 

 Russia. By N. Ozerelskovsky. P. 321. Stakes pointed at both 

 cuds are driven into the ground, approaching near each other at 

 the bottom, but diverging at the top, so as to resemble a funnel, or 

 inverted cone. To the top of each stake is tied an oat straw with 

 the grain on it. A long stake stands up in the middle of this 

 niachino, likewise crowned with oats. To this is attached a hori- 

 zontal stick, vacillating freely within the cone. The birds come to 

 eat the oats and light on this stick. It gives way and lets them fall 

 into the cone, where, not being able to use their wings, they remain 

 prisoners, till the proprietor of this singular trap comes and takes 

 them out.
