"Can't I know, mamma?" he asked, feeling sure that some joke or secret was afoot.

"Yes, dear, all in good time. Go now and see if Mr. Patterson has found the May-flowers you hung on his window."

Away went Bertie to the balcony, found the posy gone, and the room empty; so he turned about and was going back, when all of a sudden he saw something that nearly took his breath away with surprise and delight.

Now you must know that the house on the other side of Bertie's jutted out a little, and the niche thus made was covered with a woodbine that climbed up from the grass-plot below. All summer this vine rustled its green leaves above that end of the balcony; in the autumn it hung crimson streamers there, and through the winter the sparrows loved to cuddle down among the twisted stems, sunning their backs in the sheltered corner, and pressing their downy breasts against the warm bricks. Bertie used to hang great shells full of plants there, and called it his garden, but now something even more delightful and ornamental than ivy or flame-colored nasturtiums met his eye.

Up among the budding sprays stood a charming little house, with a wide piazza all round it; a white house, with cunning windows and a tiny porch, where the door stood hospitably open, with the owner's name painted on it.

When Bertie read "C. Twitters," he had to hold on to the railing, lest he should tumble over, so pleased was he with this delightful surprise. As if nothing was wanting to make it quite perfect, Cocky himself came flying up to say "Good morning;" and after a long survey of the new house went to examine it. He walked all round the piazza, sat upon the chimney to see if that was all right, popped his head into the porch, appeared to read the name on the door, and to understand all about it, for with one shrill chirp, he walked in and took possession at once.

Then Bertie danced for joy and called out, "Oh, mamma, come and see! He likes it; he's gone in, and I'm sure he means to live there!"

Mamma came, and so did Mr. P., both pretending to be much amazed at Cocky's daring to build a house so near without asking leave.

But Bertie was not deceived a bit, and hugged them both on the spot, with many thanks for this charming joke, while Cocky sat at his door and twittered, like a grateful, happy little bird, as he was.

That was only the beginning of it; for the interesting things that happened after this May-day were too many to tell. Cocky was married at once, and went to house-keeping in his new villa. Mrs. Twitters evidently liked it extremely, and began to bring in her straw furniture and feather-beds, like a busy little house-wife. Papa Twitters came too; though they had a hard job to get him there, he was so lame with rheumatism. But the vine helped the poor old dear; for after he had got safely across the street, he hopped up the woodbine, little by little, till he got to the porch, and there sat down to rest.
