THE ORANGE 87 
i. The position of the seeds in each segment. 
j. The two layers of color in the skin, 
k. The small, round, orange-colored bodies in the 
outside layer of the skin. 
Vertical Section 
10. Make a vertical section and notice the long, thin, 
white ine running down the middle; the even 
layer of skin. 
Look at the plate of the lemon and compare this 
even layer with layer over the lemon, particu- 
larly with the part we called the ‘ nose.” 
Notice the Jittle pit at the stem end. 
11. You must now get out one whole segment without 
breaking its delicate covering. 
Hold the segment up to the light. Are there any 
seeds in it? How many? 
Rip open the narrow edge with a pin or a knife 
point and throw back the white skin on one side. 
Do you see the little juice bags or juice sacs 
packed close together lying across the segment? 
12. Try to get out one of these juice sacs without 
breaking it. If you succeed in getting a whole 
one, lay it on your finger and prick it with a pin. 
You will find in it one drop of orange juice.
