The Missouri Poultry Experiment Station, T. C. Patteeson (Breeder's Gas., 

 69 (1916), No. 7, pp. 367, 368, figs. 10).— A discussion of the situation, equip- 

 ment, and work of the Missouri State Poultry Experiment Station, at Mountain 

 Grove, Mo. 



From observations for several years of egg-laying contests the author 

 believes that more depends on the strain than on the variety, for it is not 

 uncommon with two pens side by side of the same variety for one to average 

 perhaps 180 eggs per hen, while the other pen averages only 80 or 90 eggs. 

 The difference seems to be that one man has carefully selected and bred for 

 egg production, while the other has not. Another point of importance is the 

 uniformity of size, shape, and color of the eggs. The strain seems to influence 

 this as much as the number of eggs produced.
