Fill a large-mouthed 2 -quart jar with selected eggs and pour the liquid 
over them to fill the jar. Fill with a little sterilized water if necessary. 
Seal and label properly. After this has remained at the school long 
enough to make its impression, allow the pupil furnishing the eggs to 
take them home. Make a chart by copying figure 13 on large manila 
paper. 
Correlations. — Make arithmetical problems out of the following 
data, substituting local prices if it is desired. April eggs average 20 
cents a dozen, May eggs 18, June and July eggs 16, August eggs 20. 
October sales quoted 25 cents, November 30, December 35, January 
40, February 35. One quart of water glass costing about 25 cents 
will make 10 quarts when diluted and will preserve as many as 12 or 
15 dozen of eggs. Find saving if May eggs preserved as suggested 
are used in December. Preserve 10 dozen eggs in May, 20 dozen in

dwarf Essex rape, and other green crops may be sown in one yard 
while the flock uses the other. (See p. 28). 
(2) Field and garden crops to be fed to poultry. Buckwheat
