HIRD'S EGGS, SUPPLIES, EFC. 73 



Always use a soft lead pencil in marking eggs. Never 

 ink. 



The well-filled data blank, as given on the preceeding. 

 page, is self explanatory : 



The No. "516" refers to the number as given in 

 Ridge way's Nomenclature, those used in this catalogue. 



Set mark "3" signifies that this is the third clutch 

 of the Killdeer, taken by the collector during the season. 



The figure, letter or character you use in marking the 

 eggs of one clutch to distinguish them from those in 

 another of the same species should always be duplicated in 

 the data blank in the space following the words, "set 

 mark. " 



When figures are used for dates, either on the blank or 

 on the egg, the month should be placed first, thus: 

 5-15-84, for May 15th, 1884.
