p. 372, No. 1). Whether these trees were really native in the 
county it is now impossible to decide. According to Dr. 
Joyce, the Fir tree has not given its name to many places in 
Treland, which may be taken as showing that it had become 
quite rare in very early times, and even in the few place- 
names into which it enters, it is quite open to question 
whether the living tree or bog-deal is referred to. No native 
Fir is now known in Kerry although it occurs as a planted 
tree nearly throughout the county. Several of these trees 
have attained to large dimensions, as about Mahony’s Point 
and elsewhere in the neighbourhood of Killarney, 
Seedling Firs, not much more than an inch in height, have 
several times been noted in the summer months growing 
abundantly on the damp shrunken margin of the Lower 
Lake, Killarney ; they appear, however, to be destroyed by 
the first rise of water.]

VIII. Abundant in several spots in the Lixnaw canal and in 
the River Brick, 1902-07; sparingly in roadside ditches 
about Sleveen and again one mile south of Cashen Ferry 
bridge, 1904 ; sparingly in the River Feale about Listowel, 
1897-1908, this locality extends into--IX.: R.W.S., Cyb. 1898.

This North American water-weed was first noticed in 
Treland about 1836 and spread like a plague over the greater 
portion of the country within twenty-five years. It seems 
to have taken but a slight hold in Kerry considering the 
many suitable localities the county offers. It appears, 
however, to be increasing in the stations recently examined,
