ing the latter part of September. If the bog is vined with a variety 
of early berries it will not be difficult to have them picked early so 
that flooding can be done at the proper time. With late berries, such 
as Howes, this treatment is not in vogue and some other remedy must 
be attempted. It is of course essential to have sufficient water in 
storage to accomplish the fall flooding, and a lack of storage water 
at this season of the year is the stumbling block which limits the 
practice of fall flooding to a very few of the New Jersey bogs. 
If the fall flowage is applied later than the first week in October 
most of the worms will not be killed, as is shown in the following 
notes made on a bog at Mays Landing, N. J.: On October 15 the 
bog was examined and was found to have been severely damaged. 
A search for larve and cocoons was made, and 30 larvee in cocoons 
and one naked larva were secured. The flowage was put on October 
22 and held until November 8, a period of 17 days. On November 
17 another examination was made, and 26 live larve and 1 dead 
larva in cocoons were collected. This treatment was therefore en- 
tirely unsatisfactory. 
At Pemberton, N. J., a newly infested bog was flooded from Sep- 
tember 19 to October 3, a period of 14 days, with the result that the 
following season no further dying of the vines occurred and no flight 
of moths was observed. This indicated very successful control: 
Fall flooding immediately after picking the crop, whether this be 
early or late, is a treatment to be commended, even though girdlers 
are not present, since it helps in the control of the yellow- 
headed fireworm (Peronea minuta Rob.), the red-striped fireworm 
(Gelechia trialbamaculella Cham.), the toad bug (Phylloscelis atra 
Germ.), the blossom worm (L£'piglaea apiata Grote), and other in- 
sects of minor importance. 
SPRING FLOODING. 
Wherever opportunity offered, examinations were made of bogs 
after the reflowage had been removed in the spring, to determine if 
flooding during the pupa stage for various lengths of time had 
killed the pupe. In the season of 1915 a bog from which the winter 
flowage had been drawn on May 10 was reflowed June 9, and a cer- 
tain area, known to be infested, was watched to ascertain the number 
of hours it was covered by the flowage. This period proved to be 
24 hours, and soon afterward two cocoons, each of which contained 
a live pupa, were found upon the bog. Moths issued from these 
pupe on June 15 and June 19. From another area on the same 
bog, which had been submerged about 30 hours, 11 cocoons were 
collected, and these yielded 10 pupe. Moths issued from these pup 
as follows: June 14, three; June 15, two; June 16, one; June 17, 
three.
