exposed, and which, when affected, appear as if operated 
upon by worms. . . . Timber affected in this way is 
denominated by raftsmen, ‘ pecky.’ ’’ 
Sargent * says of the cypress: ‘It is often injured, 
especially west of the Mississippi river, by a species of 
Daedalea not yet determined, rendering it unfit for lumber.”’ 
Farlow,} writing in Sargent’s Silva, notes that «a species 
of dry rot in living timber often diminishes its value, and 
in Louisiana and Mississippi is said to affect at least one- 
third of all the trees.’ Rather recently Roth t mentions 
its occurrence in the South, and briefly describes its appear- 
ance. Beyond these few notes, nothing appears to have 
been said of the disease. 
OCCURRENCE. 
Taxodium distichum is now found from South Carolina 
to Florida (some trees occur as far north as New Jersey §) 
thence to Louisiana and northward as far as southern Indiana 
and southeast Missouri. Wherever the cypress grows to 
any size, it shows the ‘ pecky ’’ disease, the prevalence of 
which appears to be very variable. The exact percentage is 
difficult to ascertain as it varies materially with the locality. 
Roth (1. ¢.) says that 30% of the entire cypress supply is 
damaged by this disease. As a rule one may say that 
wherever the cypress grows, one will find it ‘* pecky,’’ and 
that there are no regions where all trees are sound. As 
for particular localities, Roth mentions a tract of land in 
Florida, which had to be abandoned entirely on account of 
‘* pegginess.’’ In the Mississippi Valley by actual count it
