 descending from above, and twinkling like stars in the 

 sun, so as to draw the attention of the most incurious. 

 The flakes of the web on this occasion hung so thick 

 upon the hedges and trees, that baskets-full might have 

 been collected. No one doubts, he observes, but that 

 these webs are the production of small spiders, which 

 swarm in the fields in fine weather in autumn, and have
