CATERPILLARS BY THE QUART. Saratoga, N. Y., has hit upon a novel 

 but apparently effective method of exterminating the caterpillars which 

 had started out to destroy the street shade trees. The village authorities 

 offered to pay so much a quart for all catterpillars brought to them to be 

 burned or buried alive. One day three hundred people, residents and 

 visitors, brought the pests in pails and pans and received twenty cents a 

 quart for them. Nearly $200 was paid out in one day. This method is 

 found to be much more effective than spraying the trees. Neit'spaper.
