SWEET GUMS AND SYCAMORES ATTACKER.

Camphor tree (Cinnamomuni camplwra). — Camphor trees which 
were abundantly punctured were observed at Gainesville, Fla., and 
at Abbeville, La., the writer was informed that two camphor trees 
planted near that town had been killed by sapsuckers. 
THE SWEET GUM FAMILY (ALTIXGIACE.E) . 
Only one species of this family occurs in the United States. It 
is vigorously attacked by sapsuckers apparently throughout its range, 
but, so far as we know, is never killed. 
Sweet gum (Liquidamhar styraciflua) . — A tree in the Agricultural 
Department grounds has a great many girdles of sapsucker pecks. 
At the Santee Club, South Carolina, almost every sweet gum tree 
bears sapsucker work, 
the bark of some being 
perforated as thickly 
as possible from top to 
bottom. At Gaines- 
ville, Fla., a large pro- 
portion of the trees are 
abundantly punc- 
tured, and the tree 
seems as much a fa- 
vorite at Abbeville, 
La.

THE SYCAMORES 
(plataxaceje) . 
Two of the three 
native species are at- 
tacked by sapsuckers, 
and although the work disfigures the smooth white bark, it is not 
known to decrease the vitality of the trees.
