BUREAU OF PLANT QUARANTINE 
[Apr.-June 
Sterilization will be done under the supervision of plant quarantine inspec- 
tors of the Bureau of Plant Quarantine. These inspectors shall at all times 
be given access to fruit while in process of sterilization. They will supervise 
the movement of the fruit from the docks to and from the sterilization rooms. 
Shipments offered for entry may be allowed to leave customs custody under 
redelivery bond for sterilization. Final release of the shipment by the col- 
lector of customs and cancelation of the bond will be effected after the in- 
spector of the Bureau of Plant Quarantine has notified the collector of cus- 
toms that the required treatment has been given. 
In authorizing the entry of fruit into the United States, sterilized in accord- 
ance with the above requirements, it should be emphasized that inexactness 
and carelessness in applying the treatment may result in injury to the fruit, 
but, in event of resulting injury, neither the Department of Agriculture nor 
its employees will be responsible.

CITRUS CENSUS OF THE LOWER BIO GRANDE VALLEY OF TEXAS AS OF APRIL 1, 1934 
In administering the provisions of the Mexican fruit-fly quarantine it is 
necessary to know from year to year the number of citrus trees planted in the 
lower Rio Grande Valley of Texas. In response to requests from the citrus 
interests of this valley and of various other interested persons, this informa- 
tion is made available to the public. 
A complete recheck of all groves was made necessary this year on account 
of the mortality among the trees as a result of the storm of September 1933. 
Included in these census figures are a total of 176,812 citrus trees which are 
considered noncommercial. 
The census is presented in two arrangements, by counties and by districts. 
The 12 districts as shown in table 2 represent divisions of the territory which 
have been made for the convenience of administration. These divisions are 
designated by the names of the towns in which suboffices of the Mexican fruit- 
fly project are located. 
In explanation of the tables the following information is given : 
Ages cf trees: In the tables the ages of trees are classified as 0, 1, 2, 3, 4, 
and 5. Trees given under classification were planted during the period from 
April 1, 1933, to March 31. 1934. Trees given under classification 1 were 
planted from April 1, 1932, to March 31, 1933. Trees given under classification 
2 were planted from July 1, 1931, to June 30, 1932. The ages of trees desig- 
nated as 3 and 4, respectively, will be understood in the light of this explana- 
tion. Trees given under classification 5 were planted previous to June 30, 1929.

darins, satsumas, sour oranges, tangelos, lemons, etc.
