The Pepo, or Melon. — Next examine a gourd, cucumber, squash, or any kind of melon, and compare its blossom end with that of the pome. Do you find any remains of a calyx, or other part of the flower 1 Examine the peduncle and observe how the fruit is attached to it. Cut cross and vertical sections, and sketch them, labeling each part. There may be some difficulty in making out the carpels, for they are not separate and distinct as in the pome, but confluent with the enlarged receptacle, which in these fruits forms the outer portion of the rind,i and also with each other at their edges, so as to form one unbroken circle, as if they had all grown together. And this is precisely what has happened. The number of carpels can easily be distinguished, however, by counting the placentas, which divide the interior into compartments called cells or loculi, corresponding in number to the num- ber of carpels. The placentas are greatly enlarged and modified, and it may be necessary to refer to the dia- gram. Figure 125, in order to make them out. How many cells, or chambers, are there in your How many placentas ? Are the seeds vertical, as in the apple, or horizontal.'
