from the particular mating 622. But the parents of bird 244 

 are given on the sheet where 244 itself appears as a chick and 

 as an adult. Hence, there is formed a direct connection in the 

 records between all the individuals in a line of descent. All 

 ramifications of a pedigree may be followed with ease, and very 

 quickly. The mating numbers inserted in the column headed 

 "Matings" are inclosed in brackets. 



In the last column headed "Remarks" are put brief notes of 

 a miscellaneous character, such as references to autopsy records 

 and the like. „ 



In addition to the mating sheet just described it is often 

 desirable to make out also for each mating on an ordinary hori- 

 zontal ruled sheet of the same size punched to go into the same 

 note books a general account of the mating with a statement of 

 the specific purpose for which this mating was made. This 

 record should include all pertinent data regarding the mating. 

 The sheet on which this record is made should have the mating 

 number placed in the upper right hand corner.

For each individual used in breeding there is made out a 

 record sheet which sets forth the data regarding this individual 

 which are regarded as of importance in the breeding work. 

 These sheets, which are of uniform size with all the other record 

 sheets, bear in the upper right hand the band number of the 

 individual. They are filed consecutively in the order of these 

 numbers. On the sheet for a particular bird are recorded, 

 besides it band number, the following data. 



1. The mating number of the mating from which the bird 

 to which the sheet pertains originated. 



2. All mating numbers of matings into which this bird as 

 an adult enters. 



3. The chick band number of the bird. 



4. A description of the bird. This will vary in extent and 

 in character with the purpose for which the bird is used as a 

 breeder. 



These records are kept on ordinary sheets with horizontal 

 rulings. No specially ruled blank form is necessary.
