She brought down thirteen more bubbles of air and then the house was filled with it. On the lower side of the open doorway there was water and on the upper side was air, and each stayed where it should. When Mrs. Spider came into her house, she always had some air caught in the hairs which covered her body, even when she did not bring a bubble of it in her hindlegs. She had to have plenty of it in her home to keep her from drowning, for she could not breathe water like a fish. "Side doors may be all right for Sticklebacks," said she, "for they do not need air, but I must have bottom doors, and I will have them too!"
After she had laid her eggs, she had some days in which to rest and visit with the Water-Boatmen who lived near. They were great friends. Belostoma used to ask the Water-Boatmen, who were his cousins, why they were so neighborly with the Water Spiders. "I don't like to see you so much with eight-legged people," he said. "They are not our kind." Belostoma was very proud of his family.
"We know that they have rather too many legs to look well," said Mrs. Water-Boatman, "but they are pleasant, and we are interested in the same things. You know we both carry air about with us in the water, and so few of our neighbors seem to care anything for it." She was a sensible little person and knew that people who are really fond of their friends do not care how many legs they have. She carried her air under her wings, but there were other Water-Boatmen, near relatives, who spread theirs over their whole bodies, and looked very silvery and beautiful when they were under water.
One day, when Mrs. Water Spider was sitting on a lily-pad and talking with her friends, a Water-Boatman rose quickly from the bottom of the pond. As soon as he got right side up (and that means as soon as he got to floating on his back), he said to her, "I heard queer sounds in your house; I was feeding near there, and the noise startled me so that I let go of the stone I was holding to, and came up. I think your eggs must be hatching."
AS SOON AS HE GOT TO FLOATING ON HIS BACK.

"Really?" exclaimed Mrs. Water Spider. "I shall be so glad! A house always seems lonely to me without children." She dove to her house, and found some very fine Water Spider babies there. You may be sure she did not have much time for visiting after that. She had to hunt food and carry it down to her children, and when they were restless and impatient she stayed with them and told them stories of the great world.
Sometimes they teased to go out with her, but this she never allowed. "Wait until you are older," she would say. "It will not be so very long before you can go safely." The children thought it had been a long, long time already, and one of them made a face when his mother said this. She did not see him, and it was well for him that she did not. He should have been very much ashamed of himself for doing it.
