tree on any given 10 a;re orchard in the county. Where orchards are 

 less than 10 acres the diagram is cut down, and where more than 10 

 acres it is platted in 10-acre sections. Three copies of all plats are 

 made, and used as follows: One is given to the foreman of the eradica- 

 tion work and is used in locating the trees in the orchard when that 

 work is done, one copy is filed in the office of the horticultural commis- 

 sioner, and one is given to the owner of -the orchard. 



The inspector keeps the notes taken at the time the infested tree was 

 found and thus has a permanent record. By these means the identifi- 

 cation of all infested trees is made absolutely correct. The plats of 

 each orchard for the consecutive years or inspections are kept together 

 and present in each case a full brief of the course of the insects in each 

 orchard. The work of inspection is at present being fully cared for in 

 the entire 12,500 acres by six inspectors. The older part of the orchards, 

 comprising- about 5,000 acres, is inspected as near as may be once a 

 year. It is in these orchards that the pests were established when the 

 inspection began, and as most of the trees are large seedling orange 

 trees, from twenty to twenty-iive years old and 30 feet high by 20 feet 

 in spread of branches, it can be seen that an inspector must needs be 

 ex£>ert to safely inspect from 2 to 3 acres of such trees per day. The 

 younger part of the orchards comprises about 7,500 acres, and contains 

 mostly navel orange trees. These trees have all been set out since 

 the horticultural commission was established, and as every tree was 

 inspected and none allowed set out unless it was clean of insect pests 

 these orchards have grown up under good care and not to exceed 

 20 trees infested with pests have ever been found in the whole 7,500 

 acres. An attempt is made to inspect this part of the orchards once 

 in two years. The work has always been such that the efficiency of 

 the inspection was of the highest importance. In case of such pests 

 as the red scale, for instance, if an inspector should fail to find it on a 

 tree, before the routine brought the insx^ector around to the orchard 

 again not only would that tree be badly infested, but a dozen trees or 

 more perhaps in its immediate vicinity would be affected also. The 

 policy has been to use every endeavor to stamp the pests out, and to 

 that end every tree found infected has been treated. If the infection 

 was slight and only on a few leaves or one or two twigs, the branches 

 were cut out liberally and burned. This was found to be quite suffi- 

 cient in almost all of such cases, and thousands of trees have been 

 cleaned in this way by the inspectors, and have never since shown 

 infestation. By this system of reports, records, plats, etc., it is pos- 

 sible to keep track of every tree in all this 12,500 acres and find all of 

 the data in our office, and all arranged in very simple manner. A tree 

 selected at random anywhere in this valley can be taken, and the 

 records of the commission will show whether it was ever found infested 

 with pests, and what kind, also how many times, and the dates when 

 it was inspected, name of the inspector who examined it each time, 

 and if it has been found affected with pests when it was treated and 

 what with, also what variety of fruit the tree is.
