The first two years of the Vineland contest: A study of the results ob- 

 tained during; the first two years at the Vineland international egg-laying 

 and breeding contest, H. R. Lewis, R. R. Hannas, and E. H. Wene (Neio 

 Jersey Stas. Bui. 338 {1919), pp. 5-96, pis. 7, figs. 5i).— The authors tabulate 

 and discuss various records secured during the first two years of the Vineland 

 egg-laying contest begun November 1, 1916, and ended three years later. Th'j 

 contest .started with 100 pens of 10 pullets each, which were trap-vested for two 

 years. During the spring of 1918 a male was added to each pen and chicks 

 were raised from the eggs. During the final year daughters of the original 

 birds occupied the pens. 



The data presented include the exhibition .scores by breeds, egg records of 

 Individual birds each year, length of molting period, body weights of birds of 

 different breeds, egg weights, feed consumption, amount of broodiness, financial 

 returns, hatching and brooding results, and mortality. The interrelationship 

 of many of the.se are shown by means of graph.s. Some of the more important 

 data have been noted from preliminary reports in Hints to Poultrymen (E. S. 

 R., 41, p. 76; 42, p. 170). The following table compares the four breeds entered 

 with respect to egg production and broodiness as pullets and as yearlings:
