88 BOULDEE KEVERIES. 



A great yellow and black butterfly, the giant 

 swallow-tail, 16 goes lazily by on slow flapping 

 wing about five feet above the earth. Its early 

 life was doubtless spent in the leaves of that 

 clump of prickly-ash, which flourishes in the 

 lowland just around the bend. Its cousin, 

 the zebra swallow-tail 17 soon appears, seeking, 

 doubtless, some papaw bush on which to ovi- 

 posit. Next comes the blue swallow-tail, 18 flut- 

 tering close to earth in search of the wild ginger, 

 which grows along these shaded banks and fur- 

 nishes food for many a larva of this brilliant 

 species. Lastly appears the tiger swallow-tail, 19 

 as usual 20 to 40 feet in air, for its cradle home 

 is in the trees, ash, tulip, poplar or hawthorne, 

 on whose foliage it feeds and swings. Thus 

 each species flies low or high according as its 

 food plant is herb, shrub or tree. Four swallow- 

 tails within ten minutes ! But two other species 

 occur within the State, and they may wing their 

 way in sight before I part company with these 

 old boulders.
