Place the eggs of different sizes side by side and note how, by the 

 law of contrast, the small eggs look smaller when compared with the large 

 eggs than they do when seen in a group by themselves. It pays to produce 

 eggs of uniform size and shape, and to grade eggs carefully before mar- 

 keting them. 



(b) Color of eggs. 



Compare the variations in color of the different collections of the 

 different kinds of eggs. Represent these by giving the proper tint to the 

 eggs already drawn in outline. 



Arrange the dark-colored and the light-colored eggs in such a manner 

 that there shall be a perfect graduation and blending of colors from the 

 darkest brown to the purest white. Note the great contrast in color when 

 the brownest and the whitest eggs are placed side by side. Group the 

 tinted eggs together and note how much darker the light brown eggs appear 

 when placed by the side of the white eggs than they do when placed by the 

 side of the brown eggs. Note also how much darker the whitish eggs 

 appear when contrasted with the pure white eggs than they do when seen 

 by the side of the light brown eggs. 



Observe how much more attractive a dozen pure-white eggs and a 

 similar number of brown eggs appear when grouped alone than they do 

 when mixed together. Those who sell eggs find that it pays to provide 

 eggs that are uniform in color. 



(c) Texture of eggs. 



Note the differences in texture of the eggshells from the different kinds 

 of poultry — the glossy, the smooth, the rough, the thick, and the thin 

 shells. The differences in texture of the shell are usually breed character- 

 istics and may be used to determine the kind of fowl that laid the egg. 

 Sometimes fowls lay eggs which have abnormal shells because there 

 is a deficiency in lime due to improper feeding. In this case the eggs 

 are not likely to hatch well or to produce strong chickens if they should 

 hatch. Only those eggs that are perfect in the size, shape, color, and 

 texture characteristic of the breed should be used for hatching purposes. 

 A hen is likely to produce eggs which in every respect are similar to the 

 egg from which she herself was hatched. 



(d) The kinds of eggs laid by the different species, breeds, and varieties. 

 Cover the label which tells the kind of fowl that laid the egg and give 



each egg a number. 



Hand each pupil a paper on which to write the number of each egg 

 and the name of the fowl that laid it. The papers can then be corrected 

 by permitting the pupils to exchange papers and mark " correct " or 

 " incorrect " as the teacher holds up the egg to the class and gives the 

 name of the fowl that laid it.
