shipments of infested trees would never have reached the valley. As it is they will have to be followed vigilantly in the field with reference to their en- durance of the present summer and due precautions taken against further i'm portations in the future"
 Before he left for the coast Mir. Nor Till said that he has not yet completed his examination of the orchards of this valley. He has been over about five sections of the citrus belt and found no scale which has attained to such proportions in California; nor did he find any evidence of the white fly of Florida.
 "The only pests here, if they can be called pests,' he said, are those minor importance and destructability. They are not of sufficient importance to justify the expense of spraying. They are, first, the thrip which is generally distributed The thrip destroys new foliage to some extent but is not dan ecrous The thrip fluctuates from year to year and next year the valley might be entirely free from them. No investigation has ever been made of this bug nor is there at present perhaps need for it. l shall look up the thrip in California and see if l can identify it as of the same species as this one Next to the thrip comes the grasshopper and the red ant found almost everywhere in the southwest. In the strict sense of the word none of these may be called citrus pests"

 Pursuant to the plan of operations adopted by the Commission at its meet ing Of March 90. spraying operations for codling moth were begun in early April in the apple orchards of Dis trict No 1. This work was begun with the assistance of Prof J. J. Thornber of the Experiment Station. who has been effectively followed by MT R. F.. l.. Wixom, Quarantine Inspector for the District.
 In the course of the season ending June 90, 1903, MT. W1Nom has inspected practically all of the orchards of his district, about 275 in number. Mir. Wixom reports the following insect pests and plant diseases as generally prevalent throughout the district:
 l. Woolly aphis. This insect is caus- ing serious damage in many orchards, and must be vigilantly combated, es- pecially in late fall or early spring when it is more easily reached
 9 Cooling Moth. During the season 275 owners in the district have sprayed a total of 33.922 trees. Most of the trees were sprayed two and three times and will receive yet another spraying before the close of the season. Lead arsenate has been chiefly employed.
 3. Root-rot. This disease is quite widely prevalent. but little understood. It especially affects apple trees.
 4 Red Mite. The work of this min ute creature is recognized. usually first on the lower limbs. by the rusty ap- pearance of the foliage. which finally
