90 THE MONTHLY BULLETIN. 



in the order in which performed and other notes on the particular case 

 in question are entered later as occasion may require ; third, card index 

 sj'stem, with a separate card for each shipment and each grove, on which 

 may be shown records of inspections, with pests found; records of 

 treatments, with material used, and results; and if desired, a cross 

 reference to other cards showing the same pest or treatments in other 

 cases. This system has appealed to the writer as so far superior to the 

 others mentioned that it will be presented in detail, with just this brief 

 reference to the other systems. 



For such a system there must be some method of designating the 

 orchard besides the owner's name, for especially in the citrus districts 

 property changes hands so often, that such a designation alone would 

 mean very little. In Ventura County we have adopted a plan briefly 

 as follows : The county is divided into several districts — for convenience 

 road districts may be used, numbered consecutively through the county. 

 Each of these districts is divided into zones by road boundaries and 

 these zones are numbered consecutively through the district. Every 

 grove or piece of property in the zone is numbered in rotation, follow- 

 ing as far as possible a definite direction in numbering. In other 

 words, each grove or piece of property has three numbers in our 

 records, as for instance, Patterson Ranch, Simi, 14-1-21 ; Teague Lemon 

 Co., Santa Paula, 5-7-8. These numbers are recorded on copies of 

 county maps made in our office, which are on file both in our office and 

 with the local inspector. A list of owners is kept in conjunction with 

 the maps which may be corrected from time to time from the official 

 county records or the personal Imowledge of the inspectors. While 

 there are great differences in the various localities, some such system 

 could, I believe, be used to advantage in almost every county. "We have 

 not applied this system to town work where the houses and yards may 

 be designated by house numbers, but have applied it to all parts of the 

 county Avhere there are commercial groves, and even to our bean and 

 beet fields. We have also made provision for the addition of new num- 

 bers with the subdivision of property. 



Let us turn now to a consideration of the records themselves. The 

 illustrations which I will use are not exact copies from any of the offices 

 but are a combination of ideas. 



First there is the record from the inspector to the main office, and 

 then a permanent record or summary for office filing. In all the inspec- 

 tor's notes, a form convenient to carry in the pocket seems advisable. 

 These may be made up in the form of loose leaf books, or they may 

 have perforated leaves with permanent stubs. Such a record for quar- 

 antine work includes variety of stock, amount, shipper, consignee, where 

 grown, pests and treatment, and in the case of orchard trees, where 

 planted. 



Each inspector sends in these forms every week, when they are num- 

 bered in rotation through the month and entered on the forms to give 

 the total inspections, or the number treated or rejected and the reasons 

 for same. 



In so far as possible, similar records are kept, whether the shipment 

 conies from outside the county or is grown locally. The co-operation 

 of all the nurservmen, even the small ones, and the constant alertness 

 on the part of the inspectors is essential in keeping this complete, but
