Egg production of virgin fowls, J. Nelson {Neiv Jersey Stas. Rpt. 1906, 

 pp. 35't-^i58, pi. /). — In continuation of earlier work (E. S. It., 18, p. 74), the 

 author found in a test covering a year that the average egg yield per hen was 

 126 in the case of a pen of 10 hens with a male bird and 118 in the case of a 

 similar lot of hens only. Eggs fi*om the two lots were stored and examined 

 at intervals to determine whether there were differences in the keeping quali- 

 ties of fertilized and unfertilized eggs. They showed large losses in weight by 

 evaporation but so far as becoming spoiled was concerned kept very well. 

 " There was no noticeable difference in the condition of the eggs derived from 

 the two pens."

 investigations reported on the cause of defects (bars) in ostrich feathers led 

 to the following conclusions : 



" There is some reason for supposing that the variations in feathers from 

 the same wing are partly associated with injuries or disturbances during 

 quilling. Whether the same feather germ will always produce the same defec- 

 tive or perfect feather yet remains to be determined.
