The cabbages were examined on September 4. Plats 1 and 5 
were found to have nearly perfect foliage, with no living cabbage 
worms and but few loopers; the inner leaves of the cabbages on 
Plats 2 and 3 were badly riddled by worms of both species. Plat 
4 was practically free of the cabbage worms, but showed many 
loopers.» The plats were resprayed on the day of examiuation, 
no change being made in applications. Upon subsequent exam- 
ination, September 21, the results of the different treatments were 
about the same as at the first examination. The work of the 
worms on Plats 2 and 3 was more marked, the cabbages on these, 
as well as on the check plats, being worthless. Many worms were 
also found on Plat 4, but none on Plats 1 and 5. ; 
Salt.— On August 31st the owner of the field treated an acre of 
cabbage adjoining the sprayed plats with salt. When inspected 
on September 4 not a dead cabbage worm could be found on the 
whole acre; instead, plenty of living specimens were found with 
salt adhering to them and apparently not injured in the least.° 
8 The condition of Plat 4 indicates that the resin mixture used alone does 
not carry enough Paris green to kill the cabbage looper. So many of the 
cabbage worms were pupating at the time that accurate conclusions as to 
results could be drawn. 
9This brood of the cabbage worm commenced to pupate or enter the 
chrysalid stage a few days after treatment with the salt. As the worms com- 
menced to disappear soon after the salt treatment the owner of the crop 
decided that salt had laid them out, while in reality the worms were simply 
crawling away to hiding places to transform into the chrysalid stage. Too 
many such tests of salt, flour, road-dust, fertilizers, and similar nostrums 
seem to yield good results when used against caterpillars’ or worms, if used
