In the center of the ring of stamens are the five style-branches, which are united at the base into a short hairy column; the column is borne on the ovary, which is sunken deep into the receptacle or stem (Fig. 4). It is down these style-branches that the pollen-tube passes on its way to the ovules or embryo seeds. The top of the style is expanded into a cupped stigma on which are many glutinous points. One can observe the browning and ripening of the stigma after pollen has been deposited by wind, bees or other agencies. When the ovules are fertilized, the forming fruit enlarges regularly unless it meets with misfortune or is crowded out for lack of room and nourishment. If one cuts across the ovary or embryo fruit below the recurving sepals, one will see under a lens that it is neatly five-celled (Fig. 5). In each cell are two ovules; these, if all goes well, will ripen into ten seeds. These five cells comprise most of the diameter in the cross-section: but as the ovary enlarges and the young fruit grows, one may see that the inner part comprising the cells begins to have a character of its own and to be differentiated from the surrounding flesh. [Illustration: 5. Cross-section of the ovary.] The "blossom" falls. In reality only the petals fall. What is left is well shown in Fig. 6. Here remain the upstanding stamens with the empty anthers, and in the center one could see the five styles if the specimen were in hand. Here also are the calyx-lobes, widely spreading and even recurved. The photograph for Fig. 6 was taken May 3. On May 17 another cluster was photographed from the same tree (Fig. 7). Three of the flowers have produced sturdy young apples. The stems or pedicels have become stouter, and they begin to spread. Note that the calyx now is closed, the old stamens protruding, a circumstance that will have special significance when we become acquainted with the codlin-moth. Note also that one flower has failed, and remains as it was two weeks earlier; it will soon fall. The young apples begin to take shape. They show a glow of red on the cheek. They are fuzzy all over. One of them is already injured on one side, having been stung by a curculio or other insect: there are keen senses about the apple-tree. [Illustration: 6.
