THE CABBAGE MAGGOT.

will kill the maggot, if the latter is in direct contact with it 

 for a long enough period, but that is where the difficutly 

 lies. When once within the stalk the pest probably is not 

 always reached by the liquid, and the hardening of the ground 

 about the plant causes much of the emulsion to flow away, 

 and distribute itself where it does but little if any good, unless 

 one goes to the expense of hollowing the earth about the 

 plant's stem.

Sawdust was mixed with glue in the proportion of Yz lb. 

 of the former in i quart of the latter. The glue was not at 

 all thick, but must represent at least 2 lbs. of hard glue in i 

 gal. of water, and the mixture had about the consistency of 

 chicken feed, though rather more "sloppy." It was applied 

 warm with the hands, about the base of the plant, put well 

 up on the stem, the diameter of the mass where it came in 

 contact with the ground being about four inches, one quart 

 was sufficient for fifteen plants. The stufif quickly hardened, 

 and tho it softened somewhat during summer rains, it did 

 not disintegrate after the rain. It was applied to twelve 

 plants on June 5th, and was still in good condition on June 

 22nd. The plants so treated made an excellent showing. A 

 man can treat six to eight plants per minute. This treat- 

 ment would be hardly practicable on large acreage.
