totally eaten up by them. What he adds is re- 12. 

 markable; he fays that thefe flies were brought TURNER 

 by a long-continued north-eafl wind, and that 

 the wind getting round to the fouth, there 

 was not, in a few hours, a fmgle fly to be 

 found in the piece. 



It is highly probable that thefe infedls tra- 

 vel in flights, and that they are led about from 

 place to place by the winds, or by other cir- 

 cumftances. 



To prevent or check the devaftation com- 

 mitted by the caterpillars, various devices 

 have been practifed by farmers whofe crops 

 were ailailecl by them. Some rolled with 

 a heavy roller. Some fovved lime over the 

 plants. Others employed ducks ; and others 

 women and children to pick them off the 

 plants; 



Mr. Arthur Bayfield found ducks the moft 

 efficacious ; he collected feventy or eighty, 

 and faved feveral acres of turneps through their 

 means. He fed them twice a-day with corn, 

 under an idea that "cankers," alone, would kill 

 them. 



Mr. William Barnard found hand-picking 

 anfwer his purpofe. Five women and boys 

 picked over ten or eleven acres of hoed plants 

 in one week ; about eighteen pence an acre.
