LIME. 
rnshly air-slacked lime has also been recommended, and eight 
! ns were thickly dusted with the powder to test its value. The 
f morning after the application of the lime, only one of the eight 
found to be at all affected, and that was still alive. 
TAR-WATER. 
spray of water that had stood for several days upon coal-tar 
next thrown upon the worms, eight nearly full-grown and two 
it half-size. Three of these which were thoroughly drenched 
i the fluid, were found dead after several hours, but none of the 
srs were affected. 
mm the preceding experiments we infer that none of the sub- 
ces tried were of any practical value except the pyrethrum and 
'Sene, and that these could be used with good effect in the field 
r early in the season, before the plants had formed a head, or 
e the worm was still small. As the butterflies lay their eggs 
sinuously for several weeks, any application, to be entirely suc- 
ful, must be several times repeated.
