fumigated at the rate of one ounce avoirdupois of sodium cyanide per one hundred 
cubic feet of space with a preliminary twenty-seven inch vacuum, and an exposure 
of one hour. 
Mr. L. R. Borland, the inspector in charge of the work of the Federal Horti¬ 
cultural Board at Nogales, Arizona, recently visited the ports of Lochiel, Naco, and 
Douglas, Arizona, for the purpose of conferring with the Customs Officials concern¬ 
ing agricultural impoitations at those points. 
Mr. C. C. Halbedl, who has been stationed at Brownsville, Texas for the past 
two years assisting in the examination of freight cars and passengers’ baggage, re¬ 
cently resigned from the service of the Federal Horticultural Board for the purpose 
of entering commercial work. 
Mr. J. W. O’Brien, a Plant Quarantine Inspector of the Federal Hoiticultural 
Board located in New York City, recently intercepted in cooperation with the 
Customs officials, living larvae of the European Corn Borer in stalks of broom corn 
contained in passenger’s baggage. This material was taken from the baggage of a 
thiid-class passenger arriving from Italy who proposed to take it to Missouri. Sub¬ 
sequent to this interception, Mr. O’Brien discovered a similar collection in the bag¬ 
gage of a passenger arriving from Germany. 
Professor R. W. Harned reports that the Plant Board Inspectors of Mississippi 
have recently intercepted a dozen or more different shipments of plants from New 
Orleans which were infested with the Japanese Camphor Scale, Pseudaonidia duplex 
(Ckll.). Most of these shipments were found in Parcel Post packages arriving at 
Jackson and Gulfport, although a few were taken in express shipments. In addition 
to the foregoing, Inspector PI. D. Money located at Biloxi, Mississippi, discovered a 
truck load of Satsuma oranges from Alabama, which were heavily infested with this 
insect. At the time the discovery was made, many of the oranges had been de¬ 
livered to stores, necessitating theii confiscation and destruction. 
The Federal Horticultural Board has recently completed a fumigation house at 
Laredo, Texas, which will accommodate twenty freight cars at one exposure. This 
house was placed in operation May 4, 1923 and takes the place of the one which was 
destroyed by fire July 19, 1922. This is probably the l&igest building in the world 
used exclusively for fumigation purposes. 
In a recent communication, Professor R. W. Harned reports as follows: “The 
insect that is being known as Desiantha nociva , that was first discovered in Stone 
County, Mississippi in March 1922, has now been found in five counties; Stone, 
Harrison, Jackson, Pearl River and Plancock. Last year the insect was only noted 
as injuring Irish potatoes, although found on several other plants. So far this year, 
its greatest damage has been done to turnips. It is thought that further scouting 
will show that this insect occurs in several other counties in South Mississippi, and 
probably also in Alabama and Louisiana. It has been found close to both of these 
states. 
“The Bureau of Entomology and the State Plant Board of Mississippi are making 
a desperate fight against the sweet potato weevil in Mississippi. Many conditions 
have been favorable to the increase of the insect, and although the eradication pro¬ 
gram has not progressed as rapidly as the authorities in charge had hoped would be 
the case, the insect has to a very large extent been prevented from spreading. Al¬ 
though a great amount of scouting is being done for this insect, it has so far been
