90 EYE SPY 
has been called, and the peculiar method by which 
he turns out the froth on the stem is well worth a 
little study. He makes no secret of the process. 
If we take a grass stem, remove him from his 
liquid lair, and transfer him to another stem, we 
may witness a novel method in the preparation of 
suds. And a busy little factory it is, too, when we 
consider what a continuous demand is made upon 
it, caused by the sun's evaporation through the 
long summer day. A single mass of bubbles with 
its tenant removed quickly disappears. If the 
little insect is permitted to crawl upon our hand, 
he is apt to try the new domicile. I have never 
been able to induce him to continue up to the 
suds point, but have no trouble in locating the 
place where he begins operations.
