(2.) Late sowing. Careful observation has shown us that for Central 

 Ontario, the third weelc in June is the most satisfactory time for sowing 

 turnips to avuid in.iury by flea-beetles. By that time the perfect insects of

 many garden flowers, may be dusted with Paris green and lime, i>r, when con-
