THE MONTHLY BULLETIN. 91 



if it is SO kept our orchard census cards may be added to and corrected 

 from the quarantine cards. The nursery cards may also be filled out 

 in the same way. 



A similar type of blanks may be used by the inspectors for the 

 orchard inspection and treatment reports. Copies of the inspection 

 sheets are sent to the owner as. a warnint; or reminder whenever it is 

 deemed wise to do so. In* this way several of the commissioners feel 

 that they avoid the unpleasantness of serving the legal abatement 

 notices in many instances. 



From these notes the data is at hand to fill in the orchard records for 

 the office. On the reverse side of the treatment sheet there is oppor- 

 tunity for the inspector to note the various items which go to make up 

 the county charge for the work in case the operator is the county. 

 From this the bill can be made up in the office. 



From time to time summaries may be made from the office records. 

 For instance at the close of each fumigation season a list of properties 

 treated is arranged according to rotation of orchard numbers. This 

 record is on file in the office and a copy is sent to the inspector in charge 

 of each district. By comparing this list with the numbered map and 

 total orchard list, a glance is sufficient to show just what groves were 

 and what were not treated. If these lists are available over several 

 years, the planning of subsequent campaigns will be much simplified. 

 More than that, the inspector will be in a position to say definitely when 

 any grove was treated — something which many growers do not remem- 

 ber accurately. Summaries are also sent to the inspectors from time 

 to time of all incoming stock treated or rejected anywhere in the county 

 that they may know just what pests have been found from various 

 localities or nurseries. Other summaries of similar nature are issued 

 from time to time as they are thought advisable. 



In case some special or new pest is found and is present only in 

 limited amounts or on individual trees, cross section charts may be used 

 to record the exact location of infection. In making a tree to tree 

 inspection of any district or in making a forced cleanup looking to 

 eradication of any pests, such charts are of especial value because with 

 them a given orchard can be reinspected after treatment without going 

 to everv individual tree, but simply to those marked. 



In the matter of data for experimental work, details as to form and 

 arrangement depend entirely on the particular problem under con- 

 sideration. The main requirements are accuracy, clearness, brevity, 

 and availability. Some form of the card system, with cross reference, 

 etc.. always seems to me advisable for such work, as it most easily meets 

 all these requirements. Special card forms may be devised for .special 

 cases or general notes may be entered and referred to by index. 



Certain other things of a statistical nature are usually kept on file 

 in our offices. Among these may be numbered crop yields, irrigation 

 tables, cultural data, etc. These miLst be collected and arranged accord- 

 ing to individual requirements and they hardly come under the scope 

 of this paper. 



To complete the card .system, copies of all official notices, both abate- 

 ment and lien, should be kept on file and should be indexed both by 

 orchard number and pests. Action under such notices may be noted 

 directly upon same, and of course such treatment would be listed on 

 orchard cards.
