thoroughly sprinkled with Paris green in water, 1 lb. to 150 gal- 

 lons of water, should be spread upon the ground and left a few 

 days. The worms will crowd to the surface for food, eat of the 

 poisoned grass and die. 



This same treatment has been successfully tried for cut-worms 

 in corn fields or other crops planted in rows, the poisoned grass 

 or c'over being scattered in small bunches between the rows. If 

 the lawn has not been destroyed so that re-seeding is necessary, and 

 it is desired to treat it without disturbing the sod, then we would 

 advise the use of Kerosene Emulsion. This has been successfully 

 used for grubs in lawns at the Department of Agriculture, Wash- 

 ington, D. C. 



You wnl find an account of the Experiments in Insect Life, Vol. 

 1, No. 2, page 48. (This journal is published by the Department of 

 Agriculture and you can no doubt get a copy by addressing the 

 Secretary of Agriculture.) You will find a formula for the prep- 

 aration of Kerosene Emulsion in Dep't of Agriculture Report, 1884, 

 page 331, and also some other information on the subject that will 

 be instructive. Other articles on the treatment of cut-worms will 

 be found in Insect Life, Vol. 3, No. 5, page 247 ; U. S. Agricul- 

 tural Report 1885, page 270; Prof. Fletcher's Report, Central 

 Expt. Farms, Ottawa, Canada, 1889 ; Canadian Entomologist 

 1889, Sept. or Oct., also in the writings of Prof. Cook and other 

 entomologists to the Experiment Stations. 



As the above cut-worm goes into the chrysalid state in July, its 

 depredations are probably over for this season and it is more than 

 probable, it apparently being confined to the lawn in question, 

 that it will not give so much trouble next season. The chrysalids 

 hatch into moths in the latter part of August or September and 

 they will scatter to lay their eggs. Cut-worms are apt to be badly 

 preyed upon by parasites and thus destroyed. Should they begin 

 work again next Spring I would advise the grass trap or Kerosene 

 Emulsion treatment. Should you need any more detailed informa- 

 tion than I have given, write again. 



Yours truly,

 Entomologist for the Station,
