EGG TYPES 

 James E. Rice 



Object. — To train the pupil's power of observation, especially his 

 ability to recognize differences in size, weight, form, color, and texture 

 of eggs; to familiarize him with the characteristic types of eggs laid by 

 the different species, classes, breeds, and varieties of domestic poultry; 

 to note variations from the normal eggs, and to lead the pupil to inquire 

 into the causes for those that are abnormal; to afford the pupil training 

 in accuracy of expression in the words used to describe the various 

 forms, colors, and textures of eggs. 



Materials. — 1. A collection of eggs from as many different kinds of 

 poultry as it is possible to procure. Eggs from the domestic fowl, ducks, 

 geese, turkeys, guineas, pheasants, pea fowl, pigeon, and quail, and also 

 from many different breeds and varieties of each of these kinds of poultry. 



2. One or two insect cases (Fig. 

 2). If insect cases cannot be 

 obtained, a neat box that can be 

 covered tightly will do. 



3. Several egg drills and blow- 

 pipes. These instruments are not 

 very expensive. They can be pur- 

 chased at Ward's Natural Science 

 Establishment, Rochester, New 

 York, for twenty-five cents each. Fig. i .— A specimen for the egg collection 

 The writer has known young per- 

 sons, however, who could blow the contents from an eggshell with a straw 

 without the aid of drills or blowpipes. 



4. Pot of glue. Labels, as shown in Fig. 1. 



5. Drawing paper, drawing pencils, lead eraser, and color crayons or 

 water colors to be used when pupils have had sufficient training in color 

 work. 



6. One pair of balances or scales. 



The collection of eggs can be made permanent by blowing the contents 

 from each egg and mounting the shell on a wooden block. (Fig. 1.) 

 The mounted eggshells can then be arranged in an insect case (Fig. 2), 

 each egg being properly labeled as follows: species, breed, variety, date, 

 name of breeder, and pupil who prepared the specimen. In this form the 

 eggshells may be safely kept in the schoolroom, where they make an 

 attractive and instructive collection for general observation when not 

 desired for class instruction. From time to time pupils will be able to add 

 to the collection. When eggs are brought in from the poultry house to
