RECORDS. 



The importance of complete and correct field 

 records in systematic tick eradication can not be too 

 strongly emphasized. Without such records it is 

 practically impossible to conduct the work properly 

 during the dipping season; and at the close of the 

 season, if reliable records are not available, the tick 

 status of the herds and ranges can not be determined, 

 and the question of release from quarantine is prob- 

 lematical. 



The best and simplest method of keeping these 

 records is by use of the card-record system devised 

 by the Bureau of Animal Industry, using the form 

 known as Tick Form 48-G. This card is so arranged 

 that it furnishes all necessary information with a 

 minimum of clerical work. 



The local inspector should make a 48-G card 

 record for each herd in his territory. These indi- 

 vidual cards should be taken to the vat at every 

 dipping and proper entry made on each owner's 

 card as soon as his cattle are inspected and dipped. 

 The supervising inspector should examine these 

 records at frequent intervals to see that they are 

 correctly kept. In additional to the individual 48-G 

 record, one card, giving the total number of herds 

 and cattle, should be kept for each vat. This vat 

 record should be made in duplicate, one being kept 

 by the local inspector in conjunction with his indi- 

 vidual record, the other by the supervising inspector, 

 who will make the entries on his card from the daily 

 dipping reports rendered by the local inspector.
