The Life of the Spider 



my find corresponds with the Cross or Diadem 

 Spider (Epeira diadema, Walck.). 



When the sun reaches this part of the en- 

 closure, one of the two groups falls into a 

 great state of flutter. Nimble acrobats that 

 they are, the little Spiders scramble up. one 

 after the other, and reach the top of the stem. 

 Here, marches and countermarches, tumult 

 and confusion reign, for there is a slight 

 breeze which throws the troop Into disorder. 

 I see no connected manoeuvres. From the top 

 of the stalk they set out at every moment, 

 one by one; they dart ofi suddenly; they fly 

 away, so to speak. It is as though they had 

 the wings of a Gnat. 



Forthwith they disappear from view. Noth- 

 ing that my eyes can see explains this strange 

 flight; for precise observation is impossible 

 amid the disturbing influences out of doors. 

 What is wanted is a peaceful atmosphere and 

 the quiet of my study. 



I gather the family In a large box, which I 

 close at once, and instal it in the animals' 

 laboratory, on a small table, two steps from 

 the open window. Apprised by what I have 

 just seen of their propensity to resort to the 

 heights, I give my subjects a bundle of twigs.
