 or compression of the seed-pods. One is often startled 

 when walking about the edges of ponds in autumn, by the 

 sudden exploding of coiling pods of snap-dragon or

 thrown about for a distance of several feet. The witch 

 hazel pod gradually closes upon its elongated seeds imtil 

 the pressure becomes so great that they are forcibly 

 ejected, sometimes to a distance of thirty feet or more.
