bands on the wire makes them come in numerical order. The 

 second .column provides space for the insertion of the adult 

 baud numbers for such of the chicks coming from the mating 

 as are kept over as adult birds, either for egg record tests or, 

 in the case of cockerels for breeding purposes. In the. third 

 column is recorded the sex of each chick as soon as it can be 

 determined. In the fourth column is placed the date of hatch- 

 ing of each chick. This column is of the proper width to take 

 the ordinary band dating stamp. 



The fifth column which is headed "Matings" on the sheet 

 is intended to contain a very important part of the pedigree 

 records. In this column are inserted the mating numbers of 

 those matings into which each individual may in its adult life 

 enter. Through the mating numbers in this column the con- 

 nection is made between the parent individuals at the top of 

 the page and all their grandchildren and progeny farther re- 

 moved. An example will illustrate how this is done : Suppose 

 that an individual having an adult band number 244 has the 

 number 622 in the column heading "Matings." This will sig- 

 nify that to look up the records of the offspring of bird No. 

 .244 one must turn to mating number 622. On . that mating 

 sheet will be found a record of all the immediate offspring of 

 this bird arising from the particular mating 622. But the par- 

 ents 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 ' li a pedigree may be followed 

 with ease, and very quickly. /he 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 mat- 

 ing number placed in the upper right hand corner.
