chestnuts that were unfit for food aggregating 493 bags and 280 barrels 
were seized under the Pure Food and Drugs Act and either condemned and 
destroyed or returned under bond to claimants for reconditioning, 
Tn many cases the shipments were seized because they consisted in part of 
‘filthy animal and vegetable substance, to wit, worms, worm excreta, 
_worm-eaten chestnuts, and decayed chestnuts. Subsequent to 1916 seizures 
of wormy chestnuts in interstate shipments have continued, but these 
have been made chiefly by city and State food officials and the Bureau 
of Chemistry does not have the records of such seizures. 
"IG, F. Gravatt, of the Bureau of Plant Industry, who is conducting 
investigations in chestnut blight control in a chestmit orchard at Bell, 
_Md., states that injury from weevils is so extensive in the orcherd as to 
interfere seriously with experiments undertaken. In many instances valuable 
hybrid nuts produced in attempts to secure blight-resisting varieties have 
been so injured by weevils that they would not germinate.! 
"In central West Virginia the ground beneath beech trees (Fagus 
-emericana) is often found strewm with medium-sized branches which have 
broken off and dropped as a result of girdles made by larvae of the 
_ cerambycid species Xylotrechus gquadrimaculatus Hald. The girdles are made 
in the summer and the branches usually drop during the succeeding autumn, 
hen they are heavy with foliage and maturing nuts. Quite often young 
“beech trees are severed within a few feet of the ground. Attempts to 
destroy the insect by gathering and burning the fallen branches are only 
“partially successful, since only about 50 per cent of the larvae drop and 
‘pupate in the branches. The others remain in the stump to complete their 
transformation." 



















Experiments with paradichlorobenzene for the peach borer reported 
by O. I. Snapp, Fort Valley, Ga., substantiate those of 1921 and 1922 
as indicating that a dose of 3/4 of an ounce can be used with safety 
over an exposure period of 28 days on three and four year old peach trees 
in the latitude of central Georgia. 
4 W. D. Whitcomb, who is assisting Mr. H. K. Plank, in charge of 
camphor scale investigations at New Orleans, La., has just reported on 
nis trip of inspection ror the camphor scale. Certain nurseries of 
southwest Louisiana and southeast Texas were visitel in company with 
TPorbert Slack, Inspector, Louisiana Department of Agriculture and 
Inn gration, and R. F. Campbell, Inspector, Texas Department of Agriculture, 
The insect was found in small numbers on camphor at Lake mine aie La., 
nd on the site of a former extensive nursery at Alvin Texas, Despite 
the abundance of camphor trees at this place, the insects had not developed 
to a very large extent. Mr. Whitcomb was unable to ascertain definitely 
at factors were responsible for keeping the insect reduced, aside perhaps 
Beer: heavy winds, intense heat, and storms.
