raised under cloth grew faster and reached the desired size for trans- 
planting one week before the seedlings in the check [untreated] 
area. The screened sets were seasoned by the removal of the cover- 
ing diirteen days before the time of replanting, and showed no more 
wilting when transplanted than did the check seedlings." 
"The screened bed was entirely free of maggots, and produced 
50,000 sets, which were replanted. The check bed. of more than

three times the size, yielded only 30,000 desirable plants. The cab- 
bage maggots were generally very destructive to unprotected seed- 
lings." 
The total cost for material was approximately 40 cents for each 
1,000 plants. The screens not only protect the plants from maggots, 
but also from the flea-beetles, which often do much damage to young 
cabbage. 
For the destruction of maggots at the time zvhen seedlings are to 
be transplanted , roots not too badly infested for use should either 
be washed off with water before resetting them, in order to remove 
the maggots, or, as Professor F. L. Washburn suggests,* they may 
be dipped in a decoction of white hellebore — one part of the powder 
to tw'o parts of water. The latter treatment is preferable, for while
