trees are worth miles to see. It lias been stated 
(and denied) that the fireflies in Java all blink at the 
same time on any particnlar tree. In the Philippines they 
have no co-ordination, but very often a large number 
happen accidentally to blink at the same time, and give 
the impression of a rhythmic alternation of luminescence 
and darkness. Luminescence is also possessed by a com- 
mon centipede, which is consequently greatly feared.
